Frequently asked questions
|
||||
--------------------------
|
||||
|
||||
Q: How much data can Flot cope with?
|
||||
|
||||
A: Flot will happily draw everything you send to it so the answer
|
||||
depends on the browser. The excanvas emulation used for IE (built with
|
||||
VML) makes IE by far the slowest browser so be sure to test with that
|
||||
if IE users are in your target group.
|
||||
|
||||
1000 points is not a problem, but as soon as you start having more
|
||||
points than the pixel width, you should probably start thinking about
|
||||
downsampling/aggregation as this is near the resolution limit of the
|
||||
chart anyway. If you downsample server-side, you also save bandwidth.
|
||||
|
||||
|
||||
Q: Flot isn't working when I'm using JSON data as source!
|
||||
|
||||
A: Actually, Flot loves JSON data, you just got the format wrong.
|
||||
Double check that you're not inputting strings instead of numbers,
|
||||
like [["0", "-2.13"], ["5", "4.3"]]. This is most common mistake, and
|
||||
the error might not show up immediately because Javascript can do some
|
||||
conversion automatically.
|
||||
|
||||
|
||||
Q: Can I export the graph?
|
||||
|
||||
A: This is a limitation of the canvas technology. There's a hook in
|
||||
the canvas object for getting an image out, but you won't get the tick
|
||||
labels. And it's not likely to be supported by IE. At this point, your
|
||||
best bet is probably taking a screenshot, e.g. with PrtScn.
|
||||
|
||||
|
||||
Q: The bars are all tiny in time mode?
|
||||
|
||||
A: It's not really possible to determine the bar width automatically.
|
||||
So you have to set the width with the barWidth option which is NOT in
|
||||
pixels, but in the units of the x axis (or the y axis for horizontal
|
||||
bars). For time mode that's milliseconds so the default value of 1
|
||||
makes the bars 1 millisecond wide.
|
||||
|
||||
|
||||
Q: Can I use Flot with libraries like Mootools or Prototype?
|
||||
|
||||
A: Yes, Flot supports it out of the box and it's easy! Just use jQuery
|
||||
instead of $, e.g. call jQuery.plot instead of $.plot and use
|
||||
jQuery(something) instead of $(something). As a convenience, you can
|
||||
put in a DOM element for the graph placeholder where the examples and
|
||||
the API documentation are using jQuery objects.
|
||||
|
||||
Depending on how you include jQuery, you may have to add one line of
|
||||
code to prevent jQuery from overwriting functions from the other
|
||||
libraries, see the documentation in jQuery ("Using jQuery with other
|
||||
libraries") for details.
|
||||
|
||||
|
||||
Q: Flot doesn't work with [insert name of Javascript UI framework]!
|
||||
|
||||
A: The only non-standard thing used by Flot is the canvas tag;
|
||||
otherwise it is simply a series of absolute positioned divs within the
|
||||
placeholder tag you put in. If this is not working, it's probably
|
||||
because the framework you're using is doing something weird with the
|
||||
DOM, or you're using it the wrong way.
|
||||
|
||||
A common problem is that there's display:none on a container until the
|
||||
user does something. Many tab widgets work this way, and there's
|
||||
nothing wrong with it - you just can't call Flot inside a display:none
|
||||
container as explained in the README so you need to hold off the Flot
|
||||
call until the container is actually displayed (or use
|
||||
visibility:hidden instead of display:none or move the container
|
||||
off-screen).
|
||||
|
||||
If you find there's a specific thing we can do to Flot to help, feel
|
||||
free to submit a bug report. Otherwise, you're welcome to ask for help
|
||||
on the forum/mailing list, but please don't submit a bug report to
|
||||
Flot.

Flot 0.7
|
||||
--------
|
||||
|
||||
API changes:
|
||||
|
||||
Multiple axes support. Code using dual axes should be changed from
|
||||
using x2axis/y2axis in the options to using an array (although
|
||||
backwards-compatibility hooks are in place). For instance,
|
||||
|
||||
{
|
||||
xaxis: { ... }, x2axis: { ... },
|
||||
yaxis: { ... }, y2axis: { ... }
|
||||
}
|
||||
|
||||
becomes
|
||||
|
||||
{
|
||||
xaxes: [ { ... }, { ... } ],
|
||||
yaxes: [ { ... }, { ... } ]
|
||||
}
|
||||
|
||||
Note that if you're just using one axis, continue to use the
|
||||
xaxis/yaxis directly (it now sets the default settings for the
|
||||
arrays). Plugins touching the axes must be ported to take the extra
|
||||
axes into account, check the source to see some examples.
|
||||
|
||||
A related change is that the visibility of axes is now auto-detected.
|
||||
So if you were relying on an axis to show up even without any data in
|
||||
the chart, you now need to set the axis "show" option explicitly.
|
||||
|
||||
"tickColor" on the grid options is now deprecated in favour of a
|
||||
corresponding option on the axes, so { grid: { tickColor: "#000" }}
|
||||
becomes { xaxis: { tickColor: "#000"}, yaxis: { tickColor: "#000"} },
|
||||
but if you just configure a base color Flot will now autogenerate a
|
||||
tick color by adding transparency. Backwards-compatibility hooks are
|
||||
in place.
|
||||
|
||||
Final note: now that IE 9 is coming out with canvas support, you may
|
||||
want to adapt the excanvas include to skip loading it in IE 9 (the
|
||||
examples have been adapted thanks to Ryley Breiddal). An alternative
|
||||
to excanvas using Flash has also surfaced, if your graphs are slow in
|
||||
IE, you may want to give it a spin:
|
||||
|
||||
http://code.google.com/p/flashcanvas/
|
||||
|
||||
|
||||
Changes:
|
||||
|
||||
- Support for specifying a bottom for each point for line charts when
|
||||
filling them, this means that an arbitrary bottom can be used
|
||||
instead of just the x axis (based on patches patiently provided by
|
||||
Roman V. Prikhodchenko).
|
||||
- New fillbetween plugin that can compute a bottom for a series from
|
||||
another series, useful for filling areas between lines (see new
|
||||
example percentiles.html for a use case).
|
||||
- More predictable handling of gaps for the stacking plugin, now all
|
||||
undefined ranges are skipped.
|
||||
- Stacking plugin can stack horizontal bar charts.
|
||||
- Navigate plugin now redraws the plot while panning instead of only
|
||||
after the fact (can be disabled by setting the pan.frameRate option
|
||||
to null), raised by lastthemy (issue 235).
|
||||
- Date formatter now accepts %0m and %0d to get a zero-padded month or
|
||||
day (issue raised by Maximillian Dornseif).
|
||||
- Revamped internals to support an unlimited number of axes, not just
|
||||
dual (sponsored by Flight Data Services,
|
||||
www.flightdataservices.com).
|
||||
- New setting on axes, "tickLength", to control the size of ticks or
|
||||
turn them off without turning off the labels.
|
||||
- Axis labels are now put in container divs with classes, for instance
|
||||
labels in the x axes can be reached via ".xAxis .tickLabel".
|
||||
- Support for setting the color of an axis (sponsored by Flight Data
|
||||
Services, www.flightdataservices.com).
|
||||
- Tick color is now auto-generated as the base color with some
|
||||
transparency (unless you override it).
|
||||
- Support for aligning ticks in the axes with "alignTicksWithAxis" to
|
||||
ensure that they appear next to each other rather than in between,
|
||||
at the expense of possibly awkward tick steps (sponsored by Flight
|
||||
Data Services, www.flightdataservices.com).
|
||||
- Support for customizing the point type through a callback when
|
||||
plotting points and new symbol plugin with some predefined point
|
||||
types (sponsored by Utility Data Corporation).
|
||||
- Resize plugin for automatically redrawing when the placeholder
|
||||
changes size, e.g. on window resizes (sponsored by Novus Partners).
|
||||
A resize() method has been added to plot object facilitate this.
|
||||
- Support Infinity/-Infinity for plotting asymptotes by hacking it
|
||||
into +/-Number.MAX_VALUE (reported by rabaea.mircea).
|
||||
- Support for restricting navigate plugin to not pan/zoom an axis (based
|
||||
on patch by kkaefer).
|
||||
- Support for providing the drag cursor for the navigate plugin as an
|
||||
option (based on patch by Kelly T. Moore).
|
||||
- Options for controlling whether an axis is shown or not (suggestion
|
||||
by Timo Tuominen) and whether to reserve space for it even if it
|
||||
isn't shown.
|
||||
- New attribute $.plot.version with the Flot version as a string.
|
||||
- The version comment is now included in the minified jquery.flot.min.js.
|
||||
- New options.grid.minBorderMargin for adjusting the minimum margin
|
||||
provided around the border (based on patch by corani, issue 188).
|
||||
- Refactor replot behaviour so Flot tries to reuse the existing
|
||||
canvas, adding shutdown() methods to the plot (based on patch by
|
||||
Ryley Breiddal, issue 269). This prevents a memory leak in Chrome
|
||||
and hopefully makes replotting faster for those who are using $.plot
|
||||
instead of .setData()/.draw(). Also update jQuery to 1.5.1 to
|
||||
prevent IE leaks fixed in jQuery.
|
||||
- New real-time line chart example.
|
||||
|
||||
- New hooks: drawSeries, shutdown
|
||||
|
||||
Bug fixes:
|
||||
|
||||
- Fixed problem with findNearbyItem and bars on top of each other
|
||||
(reported by ragingchikn, issue 242).
|
||||
- Fixed problem with ticks and the border (based on patch from
|
||||
ultimatehustler69, issue 236).
|
||||
- Fixed problem with plugins adding options to the series objects.
|
||||
- Fixed a problem introduced in 0.6 with specifying a gradient with {
|
||||
brightness: x, opacity: y }.
|
||||
- Don't use $.browser.msie, check for getContext on the created canvas
|
||||
element instead and try to use excanvas if it's not found (fixes IE
|
||||
9 compatibility).
|
||||
- highlight(s, index) was looking up the point in the original s.data
|
||||
instead of in the computed datapoints array, which breaks with
|
||||
plugins that modify the datapoints (such as the stacking plugin).
|
||||
Issue 316 reported by curlypaul924.
|
||||
- More robust handling of axis from data passed in from getData()
|
||||
(problem reported by Morgan).
|
||||
- Fixed problem with turning off bar outline (issue 253, fix by Jordi
|
||||
Castells).
|
||||
- Check the selection passed into setSelection in the selection
|
||||
plugin, to guard against errors when synchronizing plots (fix by Lau
|
||||
Bech Lauritzen).
|
||||
- Fix bug in crosshair code with mouseout resetting the crosshair even
|
||||
if it is locked (fix by Lau Bech Lauritzen and Banko Adam).
|
||||
- Fix bug with points plotting using line width from lines rather than
|
||||
points.
|
||||
- Fix bug with passing non-array 0 data (for plugins that don't expect
|
||||
arrays, patch by vpapp1).
|
||||
- Fix errors in JSON in examples so they work with jQuery 1.4.2
|
||||
(fix reported by honestbleeps, issue 357).
|
||||
- Fix bug with tooltip in interacting.html, this makes the tooltip
|
||||
much smoother (fix by bdkahn). Fix related bug inside highlighting
|
||||
handler in Flot.
|
||||
- Use closure trick to make inline colorhelpers plugin respect
|
||||
jQuery.noConflict(true), renaming the global jQuery object (reported
|
||||
by Nick Stielau).
|
||||
- Listen for mouseleave events and fire a plothover event with empty
|
||||
item when it occurs to drop highlights when the mouse leaves the
|
||||
plot (reported by by outspirit).
|
||||
- Fix bug with using aboveData with a background (reported by
|
||||
amitayd).
|
||||
- Fix possible excanvas leak (report and suggested fix by tom9729).
|
||||
- Fix bug with backwards compatibility for shadowSize = 0 (report and
|
||||
suggested fix by aspinak).
|
||||
- Adapt examples to skip loading excanvas (fix by Ryley Breiddal).
|
||||
- Fix bug that prevent a simple f(x) = -x transform from working
|
||||
correctly (fix by Mike, issue 263).
|
||||
- Fix bug in restoring cursor in navigate plugin (reported by Matteo
|
||||
Gattanini, issue 395).
|
||||
- Fix bug in picking items when transform/inverseTransform is in use
|
||||
(reported by Ofri Raviv, and patches and analysis by Jan and Tom
|
||||
Paton, issue 334 and 467).
|
||||
- Fix problem with unaligned ticks and hover/click events caused by
|
||||
padding on the placeholder by hardcoding the placeholder padding to
|
||||
0 (reported by adityadineshsaxena, Matt Sommer, Daniel Atos and some
|
||||
other people, issue 301).
|
||||
- Update colorhelpers plugin to avoid dying when trying to parse an
|
||||
invalid string (reported by cadavor, issue 483).

||||
Flot 0.6
|
||||
--------
|
||||
|
||||
API changes:
|
||||
|
||||
1. Selection support has been moved to a plugin. Thus if you're
|
||||
passing selection: { mode: something }, you MUST include the file
|
||||
jquery.flot.selection.js after jquery.flot.js. This reduces the size
|
||||
of base Flot and makes it easier to customize the selection as well as
|
||||
improving code clarity. The change is based on a patch from andershol.
|
||||
|
||||
2. In the global options specified in the $.plot command,
|
||||
"lines", "points", "bars" and "shadowSize" have been moved to a
|
||||
sub-object called "series", i.e.
|
||||
|
||||
$.plot(placeholder, data, { lines: { show: true }})
|
||||
|
||||
should be changed to
|
||||
|
||||
$.plot(placeholder, data, { series: { lines: { show: true }}})
|
||||
|
||||
All future series-specific options will go into this sub-object to
|
||||
simplify plugin writing. Backward-compatibility code is in place, so
|
||||
old code should not break.
|
||||
|
||||
3. "plothover" no longer provides the original data point, but instead
|
||||
a normalized one, since there may be no corresponding original point.
|
||||
|
||||
4. Due to a bug in previous versions of jQuery, you now need at least
|
||||
jQuery 1.2.6. But if you can, try jQuery 1.3.2 as it got some
|
||||
improvements in event handling speed.
|
||||
|
||||
|
||||
Changes:
|
||||
|
||||
- Added support for disabling interactivity for specific data series
|
||||
(request from Ronald Schouten and Steve Upton).
|
||||
|
||||
- Flot now calls $() on the placeholder and optional legend container
|
||||
passed in so you can specify DOM elements or CSS expressions to make
|
||||
it easier to use Flot with libraries like Prototype or Mootools or
|
||||
through raw JSON from Ajax responses.
|
||||
|
||||
- A new "plotselecting" event is now emitted while the user is making
|
||||
a selection.
|
||||
|
||||
- The "plothover" event is now emitted immediately instead of at most
|
||||
10 times per second, you'll have to put in a setTimeout yourself if
|
||||
you're doing something really expensive on this event.
|
||||
|
||||
- The built-in date formatter can now be accessed as
|
||||
$.plot.formatDate(...) (suggestion by Matt Manela) and even
|
||||
replaced.
|
||||
|
||||
- Added "borderColor" option to the grid (patch from Amaury Chamayou
|
||||
and patch from Mike R. Williamson).
|
||||
|
||||
- Added support for gradient backgrounds for the grid, take a look at
|
||||
the "setting options" example (based on patch from Amaury Chamayou,
|
||||
issue 90).
|
||||
|
||||
- Gradient bars (suggestion by stefpet).
|
||||
|
||||
- Added a "plotunselected" event which is triggered when the selection
|
||||
is removed, see "selection" example (suggestion by Meda Ugo);
|
||||
|
||||
- The option legend.margin can now specify horizontal and vertical
|
||||
margins independently (suggestion by someone who's annoyed).
|
||||
|
||||
- Data passed into Flot is now copied to a new canonical format to
|
||||
enable further processing before it hits the drawing routines. As a
|
||||
side-effect, this should make Flot more robust in the face of bad
|
||||
data (and fixes issue 112).
|
||||
|
||||
- Step-wise charting: line charts have a new option "steps" that when
|
||||
set to true connects the points with horizontal/vertical steps
|
||||
instead of diagonal lines.
|
||||
|
||||
- The legend labelFormatter now passes the series in addition to just
|
||||
the label (suggestion by Vincent Lemeltier).
|
||||
|
||||
- Horizontal bars (based on patch by Jason LeBrun).
|
||||
|
||||
- Support for partial bars by specifying a third coordinate, i.e. they
|
||||
don't have to start from the axis. This can be used to make stacked
|
||||
bars.
|
||||
|
||||
- New option to disable the (grid.show).
|
||||
|
||||
- Added pointOffset method for converting a point in data space to an
|
||||
offset within the placeholder.
|
||||
|
||||
- Plugin system: register an init method in the $.flot.plugins array
|
||||
to get started, see PLUGINS.txt for details on how to write plugins
|
||||
(it's easy). There are also some extra methods to enable access to
|
||||
internal state.
|
||||
|
||||
- Hooks: you can register functions that are called while Flot is
|
||||
crunching the data and doing the plot. This can be used to modify
|
||||
Flot without changing the source, useful for writing plugins. Some
|
||||
hooks are defined, more are likely to come.
|
||||
|
||||
- Threshold plugin: you can set a threshold and a color, and the data
|
||||
points below that threshold will then get the color. Useful for
|
||||
marking data below 0, for instance.
|
||||
|
||||
- Stack plugin: you can specify a stack key for each series to have
|
||||
them summed. This is useful for drawing additive/cumulative graphs
|
||||
with bars and (currently unfilled) lines.
|
||||
|
||||
- Crosshairs plugin: trace the mouse position on the axes, enable with
|
||||
crosshair: { mode: "x"} (see the new tracking example for a use).
|
||||
|
||||
- Image plugin: plot prerendered images.
|
||||
|
||||
- Navigation plugin for panning and zooming a plot.
|
||||
|
||||
- More configurable grid.
|
||||
|
||||
- Axis transformation support, useful for non-linear plots, e.g. log
|
||||
axes and compressed time axes (like omitting weekends).
|
||||
|
||||
- Support for twelve-hour date formatting (patch by Forrest Aldridge).
|
||||
|
||||
- The color parsing code in Flot has been cleaned up and split out so
|
||||
it's now available as a separate jQuery plugin. It's included inline
|
||||
in the Flot source to make dependency managing easier. This also
|
||||
makes it really easy to use the color helpers in Flot plugins.
|
||||
|
||||
Bug fixes:
|
||||
|
||||
- Fixed two corner-case bugs when drawing filled curves (report and
|
||||
analysis by Joshua Varner).
|
||||
- Fix auto-adjustment code when setting min to 0 for an axis where the
|
||||
dataset is completely flat on that axis (report by chovy).
|
||||
- Fixed a bug with passing in data from getData to setData when the
|
||||
secondary axes are used (issue 65, reported by nperelman).
|
||||
- Fixed so that it is possible to turn lines off when no other chart
|
||||
type is shown (based on problem reported by Glenn Vanderburg), and
|
||||
fixed so that setting lineWidth to 0 also hides the shadow (based on
|
||||
problem reported by Sergio Nunes).
|
||||
- Updated mousemove position expression to the latest from jQuery (bug
|
||||
reported by meyuchas).
|
||||
- Use CSS borders instead of background in legend (fix printing issue 25
|
||||
and 45).
|
||||
- Explicitly convert axis min/max to numbers.
|
||||
- Fixed a bug with drawing marking lines with different colors
|
||||
(reported by Khurram).
|
||||
- Fixed a bug with returning y2 values in the selection event (fix
|
||||
by exists, issue 75).
|
||||
- Only set position relative on placeholder if it hasn't already a
|
||||
position different from static (reported by kyberneticist, issue 95).
|
||||
- Don't round markings to prevent sub-pixel problems (reported by Dan
|
||||
Lipsitt).
|
||||
- Make the grid border act similarly to a regular CSS border, i.e.
|
||||
prevent it from overlapping the plot itself. This also fixes a
|
||||
problem with anti-aliasing when the width is 1 pixel (reported by
|
||||
Anthony Ettinger).
|
||||
- Imported version 3 of excanvas and fixed two issues with the newer
|
||||
version. Hopefully, this will make Flot work with IE8 (nudge by
|
||||
Fabien Menager, further analysis by Booink, issue 133).
|
||||
- Changed the shadow code for lines to hopefully look a bit better
|
||||
with vertical lines.
|
||||
- Round tick positions to avoid possible problems with fractions
|
||||
(suggestion by Fred, issue 130).
|
||||
- Made the heuristic for determining how many ticks to aim for a bit
|
||||
smarter.
|
||||
- Fix for uneven axis margins (report and patch by Paul Kienzle) and
|
||||
snapping to ticks (concurrent report and patch by lifthrasiir).
|
||||
- Fixed bug with slicing in findNearbyItems (patch by zollman).
|
||||
- Make heuristic for x axis label widths more dynamic (patch by
|
||||
rickinhethuis).
|
||||
- Make sure points on top take precedence when finding nearby points
|
||||
when hovering (reported by didroe, issue 224).
|
||||
|
||||
Flot 0.5
|
||||
--------
|
||||
|
||||
Backwards API change summary: Timestamps are now in UTC. Also
|
||||
"selected" event -> becomes "plotselected" with new data, the
|
||||
parameters for setSelection are now different (but backwards
|
||||
compatibility hooks are in place), coloredAreas becomes markings with
|
||||
a new interface (but backwards compatibility hooks are in place).
|
||||
|
||||
|
||||
Interactivity: added a new "plothover" event and this and the
|
||||
"plotclick" event now returns the closest data item (based on patch by
|
||||
/david, patch by Mark Byers for bar support). See the revamped
|
||||
"interacting with the data" example for some hints on what you can do.
|
||||
|
||||
Highlighting: you can now highlight points and datapoints are
|
||||
autohighlighted when you hover over them (if hovering is turned on).
|
||||
|
||||
Support for dual axis has been added (based on patch by someone who's
|
||||
annoyed and /david). For each data series you can specify which axes
|
||||
it belongs to, and there are two more axes, x2axis and y2axis, to
|
||||
customize. This affects the "selected" event which has been renamed to
|
||||
"plotselected" and spews out { xaxis: { from: -10, to: 20 } ... },
|
||||
setSelection in which the parameters are on a new form (backwards
|
||||
compatible hooks are in place so old code shouldn't break) and
|
||||
markings (formerly coloredAreas).
|
||||
|
||||
Timestamps in time mode are now displayed according to
|
||||
UTC instead of the time zone of the visitor. This affects the way the
|
||||
timestamps should be input; you'll probably have to offset the
|
||||
timestamps according to your local time zone. It also affects any
|
||||
custom date handling code (which basically now should use the
|
||||
equivalent UTC date mehods, e.g. .setUTCMonth() instead of
|
||||
.setMonth().
|
||||
|
||||
Added support for specifying the size of tick labels (axis.labelWidth,
|
||||
axis.labelHeight). Useful for specifying a max label size to keep
|
||||
multiple plots aligned.
|
||||
|
||||
Markings, previously coloredAreas, are now specified as ranges on the
|
||||
axes, like { xaxis: { from: 0, to: 10 }}. Furthermore with markings
|
||||
you can now draw horizontal/vertical lines by setting from and to to
|
||||
the same coordinate (idea from line support patch by by Ryan Funduk).
|
||||
|
||||
The "fill" option can now be a number that specifies the opacity of
|
||||
the fill.
|
||||
|
||||
You can now specify a coordinate as null (like [2, null]) and Flot
|
||||
will take the other coordinate into account when scaling the axes
|
||||
(based on patch by joebno).
|
||||
|
||||
New option for bars "align". Set it to "center" to center the bars on
|
||||
the value they represent.
|
||||
|
||||
setSelection now takes a second parameter which you can use to prevent
|
||||
the method from firing the "plotselected" handler.
|
||||
|
||||
Using the "container" option in legend now overwrites the container
|
||||
element instead of just appending to it (fixes infinite legend bug,
|
||||
reported by several people, fix by Brad Dewey).
|
||||
|
||||
Fixed a bug in calculating spacing around the plot (reported by
|
||||
timothytoe). Fixed a bug in finding max values for all-negative data
|
||||
sets. Prevent the possibility of eternal looping in tick calculations.
|
||||
Fixed a bug when borderWidth is set to 0 (reported by
|
||||
Rob/sanchothefat). Fixed a bug with drawing bars extending below 0
|
||||
(reported by James Hewitt, patch by Ryan Funduk). Fixed a
|
||||
bug with line widths of bars (reported by MikeM). Fixed a bug with
|
||||
'nw' and 'sw' legend positions. Improved the handling of axis
|
||||
auto-scaling with bars. Fixed a bug with multi-line x-axis tick
|
||||
labels (reported by Luca Ciano). IE-fix help by Savage Zhang.
|
||||
|
||||
|
||||
Flot 0.4
|
||||
--------
|
||||
|
||||
API changes: deprecated axis.noTicks in favor of just specifying the
|
||||
number as axis.ticks. So "xaxis: { noTicks: 10 }" becomes
|
||||
"xaxis: { ticks: 10 }"
|
||||
|
||||
Time series support. Specify axis.mode: "time", put in Javascript
|
||||
timestamps as data, and Flot will automatically spit out sensible
|
||||
ticks. Take a look at the two new examples. The format can be
|
||||
customized with axis.timeformat and axis.monthNames, or if that fails
|
||||
with axis.tickFormatter.
|
||||
|
||||
Support for colored background areas via grid.coloredAreas. Specify an
|
||||
array of { x1, y1, x2, y2 } objects or a function that returns these
|
||||
given { xmin, xmax, ymin, ymax }.
|
||||
|
||||
More members on the plot object (report by Chris Davies and others).
|
||||
"getData" for inspecting the assigned settings on data series (e.g.
|
||||
color) and "setData", "setupGrid" and "draw" for updating the contents
|
||||
without a total replot.
|
||||
|
||||
The default number of ticks to aim for is now dependent on the size of
|
||||
the plot in pixels. Support for customizing tick interval sizes
|
||||
directly with axis.minTickSize and axis.tickSize.
|
||||
|
||||
Cleaned up the automatic axis scaling algorithm and fixed how it
|
||||
interacts with ticks. Also fixed a couple of tick-related corner case
|
||||
bugs (one reported by mainstreetmark, another reported by timothytoe).
|
||||
|
||||
The option axis.tickFormatter now takes a function with two
|
||||
parameters, the second parameter is an optional object with
|
||||
information about the axis. It has min, max, tickDecimals, tickSize.
|
||||
|
||||
Added support for segmented lines (based on patch from Michael
|
||||
MacDonald) and for ignoring null and bad values (suggestion from Nick
|
||||
Konidaris and joshwaihi).
|
||||
|
||||
Added support for changing the border width (joebno and safoo).
|
||||
Label colors can be changed via CSS by selecting the tickLabel class.
|
||||
|
||||
Fixed a bug in handling single-item bar series (reported by Emil
|
||||
Filipov). Fixed erratic behaviour when interacting with the plot
|
||||
with IE 7 (reported by Lau Bech Lauritzen). Prevent IE/Safari text
|
||||
selection when selecting stuff on the canvas.
|
||||
|
||||
|
||||
|
||||
Flot 0.3
|
||||
--------
|
||||
|
||||
This is mostly a quick-fix release because jquery.js wasn't included
|
||||
in the previous zip/tarball.
|
||||
|
||||
Support clicking on the plot. Turn it on with grid: { clickable: true },
|
||||
then you get a "plotclick" event on the graph placeholder with the
|
||||
position in units of the plot.
|
||||
|
||||
Fixed a bug in dealing with data where min = max, thanks to Michael
|
||||
Messinides.
|
||||
|
||||
Include jquery.js in the zip/tarball.
|
||||
|
||||
|
||||
Flot 0.2
|
||||
--------
|
||||
|
||||
Added support for putting a background behind the default legend. The
|
||||
default is the partly transparent background color. Added
|
||||
backgroundColor and backgroundOpacity to the legend options to control
|
||||
this.
|
||||
|
||||
The ticks options can now be a callback function that takes one
|
||||
parameter, an object with the attributes min and max. The function
|
||||
should return a ticks array.
|
||||
|
||||
Added labelFormatter option in legend, useful for turning the legend
|
||||
labels into links.
|
||||
|
||||
Fixed a couple of bugs.
|
||||
|
||||
The API should now be fully documented.
|
||||
|
||||
Patch from Guy Fraser to make parts of the code smaller.
|
||||
|
||||
API changes: Moved labelMargin option to grid from x/yaxis.
|
||||
|
||||
|
||||
Flot 0.1
|
||||
--------
|
||||
|
||||
First public release.

||||
|
|

|

Writing plugins
|
||||
---------------
|
||||
|
||||
All you need to do to make a new plugin is creating an init function
|
||||
and a set of options (if needed), stuffing it into an object and
|
||||
putting it in the $.plot.plugins array. For example:
|
||||
|
||||
function myCoolPluginInit(plot) {
|
||||
plot.coolstring = "Hello!";
|
||||
};
|
||||
|
||||
$.plot.plugins.push({ init: myCoolPluginInit, options: { ... } });
|
||||
|
||||
// if $.plot is called, it will return a plot object with the
|
||||
// attribute "coolstring"
|
||||
|
||||
Now, given that the plugin might run in many different places, it's
|
||||
a good idea to avoid leaking names. The usual trick here is wrap the
|
||||
above lines in an anonymous function which is called immediately, like
|
||||
this: (function () { inner code ... })(). To make it even more robust
|
||||
in case $ is not bound to jQuery but some other Javascript library, we
|
||||
can write it as
|
||||
|
||||
(function ($) {
|
||||
// plugin definition
|
||||
// ...
|
||||
})(jQuery);
|
||||
|
||||
There's a complete example below, but you should also check out the
|
||||
plugins bundled with Flot.
|
||||
|
||||
|
||||
Complete example
|
||||
----------------
|
||||
|
||||
Here is a simple debug plugin which alerts each of the series in the
|
||||
plot. It has a single option that control whether it is enabled and
|
||||
how much info to output:
|
||||
|
||||
(function ($) {
|
||||
function init(plot) {
|
||||
var debugLevel = 1;
|
||||
|
||||
function checkDebugEnabled(plot, options) {
|
||||
if (options.debug) {
|
||||
debugLevel = options.debug;
|
||||
|
||||
plot.hooks.processDatapoints.push(alertSeries);
|
||||
}
|
||||
}
|
||||
|
||||
function alertSeries(plot, series, datapoints) {
|
||||
var msg = "series " + series.label;
|
||||
if (debugLevel > 1)
|
||||
msg += " with " + series.data.length + " points";
|
||||
alert(msg);
|
||||
}
|
||||
|
||||
plot.hooks.processOptions.push(checkDebugEnabled);
|
||||
}
|
||||
|
||||
var options = { debug: 0 };
|
||||
|
||||
$.plot.plugins.push({
|
||||
init: init,
|
||||
options: options,
|
||||
name: "simpledebug",
|
||||
version: "0.1"
|
||||
});
|
||||
})(jQuery);
|
||||
|
||||
We also define "name" and "version". It's not used by Flot, but might
|
||||
be helpful for other plugins in resolving dependencies.
|
||||
|
||||
Put the above in a file named "jquery.flot.debug.js", include it in an
|
||||
HTML page and then it can be used with:
|
||||
|
||||
$.plot($("#placeholder"), [...], { debug: 2 });
|
||||
|
||||
This simple plugin illustrates a couple of points:
|
||||
|
||||
- It uses the anonymous function trick to avoid name pollution.
|
||||
- It can be enabled/disabled through an option.
|
||||
- Variables in the init function can be used to store plot-specific
|
||||
state between the hooks.
|
||||
|
||||
The two last points are important because there may be multiple plots
|
||||
on the same page, and you'd want to make sure they are not mixed up.
|
||||
|
||||
|
||||
Shutting down a plugin
|
||||
----------------------
|
||||
|
||||
Each plot object has a shutdown hook which is run when plot.shutdown()
|
||||
is called. This usually mostly happens in case another plot is made on
|
||||
top of an existing one.
|
||||
|
||||
The purpose of the hook is to give you a chance to unbind any event
|
||||
handlers you've registered and remove any extra DOM things you've
|
||||
inserted.
|
||||
|
||||
The problem with event handlers is that you can have registered a
|
||||
handler which is run in some point in the future, e.g. with
|
||||
setTimeout(). Meanwhile, the plot may have been shutdown and removed,
|
||||
but because your event handler is still referencing it, it can't be
|
||||
garbage collected yet, and worse, if your handler eventually runs, it
|
||||
may overwrite stuff on a completely different plot.
|
||||
|
||||
|
||||
Some hints on the options
|
||||
-------------------------
|
||||
|
||||
Plugins should always support appropriate options to enable/disable
|
||||
them because the plugin user may have several plots on the same page
|
||||
where only one should use the plugin. In most cases it's probably a
|
||||
good idea if the plugin is turned off rather than on per default, just
|
||||
like most of the powerful features in Flot.
|
||||
|
||||
If the plugin needs options that are specific to each series, like the
|
||||
points or lines options in core Flot, you can put them in "series" in
|
||||
the options object, e.g.
|
||||
|
||||
var options = {
|
||||
series: {
|
||||
downsample: {
|
||||
algorithm: null,
|
||||
maxpoints: 1000
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
Then they will be copied by Flot into each series, providing default
|
||||
values in case none are specified.
|
||||
|
||||
Think hard and long about naming the options. These names are going to
|
||||
be public API, and code is going to depend on them if the plugin is
|
||||
successful.

About
|
||||
-----
|
||||
|
||||
Flot is a Javascript plotting library for jQuery. Read more at the
|
||||
website:
|
||||
|
||||
http://code.google.com/p/flot/
|
||||
|
||||
Take a look at the examples linked from above, they should give a good
|
||||
impression of what Flot can do and the source code of the examples is
|
||||
probably the fastest way to learn how to use Flot.
|
||||
|
||||
|
||||
Installation
|
||||
------------
|
||||
|
||||
Just include the Javascript file after you've included jQuery.
|
||||
|
||||
Generally, all browsers that support the HTML5 canvas tag are
|
||||
supported.
|
||||
|
||||
For support for Internet Explorer < 9, you can use Excanvas, a canvas
|
||||
emulator; this is used in the examples bundled with Flot. You just
|
||||
include the excanvas script like this:
|
||||
|
||||
<!--[if lte IE 8]><script language="javascript" type="text/javascript" src="excanvas.min.js"></script><![endif]-->
|
||||
|
||||
If it's not working on your development IE 6.0, check that it has
|
||||
support for VML which Excanvas is relying on. It appears that some
|
||||
stripped down versions used for test environments on virtual machines
|
||||
lack the VML support.
|
||||
|
||||
You can also try using Flashcanvas (see
|
||||
http://code.google.com/p/flashcanvas/), which uses Flash to do the
|
||||
emulation. Although Flash can be a bit slower to load than VML, if
|
||||
you've got a lot of points, the Flash version can be much faster
|
||||
overall. Flot contains some wrapper code for activating Excanvas which
|
||||
Flashcanvas is compatible with.
|
||||
|
||||
You need at least jQuery 1.2.6, but try at least 1.3.2 for interactive
|
||||
charts because of performance improvements in event handling.
|
||||
|
||||
|
||||
Basic usage
|
||||
-----------
|
||||
|
||||
Create a placeholder div to put the graph in:
|
||||
|
||||
<div id="placeholder"></div>
|
||||
|
||||
You need to set the width and height of this div, otherwise the plot
|
||||
library doesn't know how to scale the graph. You can do it inline like
|
||||
this:
|
||||
|
||||
<div id="placeholder" style="width:600px;height:300px"></div>
|
||||
|
||||
You can also do it with an external stylesheet. Make sure that the
|
||||
placeholder isn't within something with a display:none CSS property -
|
||||
in that case, Flot has trouble measuring label dimensions which
|
||||
results in garbled looks and might have trouble measuring the
|
||||
placeholder dimensions which is fatal (it'll throw an exception).
|
||||
|
||||
Then when the div is ready in the DOM, which is usually on document
|
||||
ready, run the plot function:
|
||||
|
||||
$.plot($("#placeholder"), data, options);
|
||||
|
||||
Here, data is an array of data series and options is an object with
|
||||
settings if you want to customize the plot. Take a look at the
|
||||
examples for some ideas of what to put in or look at the reference
|
||||
in the file "API.txt". Here's a quick example that'll draw a line from
|
||||
(0, 0) to (1, 1):
|
||||
|
||||
$.plot($("#placeholder"), [ [[0, 0], [1, 1]] ], { yaxis: { max: 1 } });
|
||||
|
||||
The plot function immediately draws the chart and then returns a plot
|
||||
object with a couple of methods.
|
||||
|
||||
|
||||
What's with the name?
|
||||
---------------------
|
||||
|
||||
First: it's pronounced with a short o, like "plot". Not like "flawed".
|
||||
|
||||
So "Flot" rhymes with "plot".
|
||||
|
||||
And if you look up "flot" in a Danish-to-English dictionary, some up
|
||||
the words that come up are "good-looking", "attractive", "stylish",
|
||||
"smart", "impressive", "extravagant". One of the main goals with Flot
|
||||
is pretty looks.
|
||||

/* Plugin for jQuery for working with colors.
|
||||
*
|
||||
* Version 1.1.
|
||||
*
|
||||
* Inspiration from jQuery color animation plugin by John Resig.
|
||||
*
|
||||
* Released under the MIT license by Ole Laursen, October 2009.
|
||||
*
|
||||
* Examples:
|
||||
*
|
||||
* $.color.parse("#fff").scale('rgb', 0.25).add('a', -0.5).toString()
|
||||
* var c = $.color.extract($("#mydiv"), 'background-color');
|
||||
* console.log(c.r, c.g, c.b, c.a);
|
||||
* $.color.make(100, 50, 25, 0.4).toString() // returns "rgba(100,50,25,0.4)"
|
||||
*
|
||||
* Note that .scale() and .add() return the same modified object
|
||||
* instead of making a new one.
|
||||
*
|
||||
* V. 1.1: Fix error handling so e.g. parsing an empty string does
|
||||
* produce a color rather than just crashing.

/*
|
||||
Flot plugin for showing crosshairs, thin lines, when the mouse hovers
|
||||
over the plot.
|
||||
|
||||
crosshair: {
|
||||
mode: null or "x" or "y" or "xy"
|
||||
color: color
|
||||
lineWidth: number
|
||||
}
|
||||
|
||||
Set the mode to one of "x", "y" or "xy". The "x" mode enables a
|
||||
vertical crosshair that lets you trace the values on the x axis, "y"
|
||||
enables a horizontal crosshair and "xy" enables them both. "color" is
|
||||
the color of the crosshair (default is "rgba(170, 0, 0, 0.80)"),
|
||||
"lineWidth" is the width of the drawn lines (default is 1).
|
||||
|
||||
The plugin also adds four public methods:
|
||||
|
||||
- setCrosshair(pos)
|
||||
|
||||
Set the position of the crosshair. Note that this is cleared if
|
||||
the user moves the mouse. "pos" is in coordinates of the plot and
|
||||
should be on the form { x: xpos, y: ypos } (you can use x2/x3/...
|
||||
if you're using multiple axes), which is coincidentally the same
|
||||
format as what you get from a "plothover" event. If "pos" is null,
|
||||
the crosshair is cleared.
|
||||
|
||||
- clearCrosshair()
|
||||
|
||||
Clear the crosshair.
|
||||
|
||||
- lockCrosshair(pos)
|
||||
|
||||
Cause the crosshair to lock to the current location, no longer
|
||||
updating if the user moves the mouse. Optionally supply a position
|
||||
(passed on to setCrosshair()) to move it to.
|
||||
|
||||
Example usage:
|
||||
var myFlot = $.plot( $("#graph"), ..., { crosshair: { mode: "x" } } };
|
||||
$("#graph").bind("plothover", function (evt, position, item) {
|
||||
if (item) {
|
||||
// Lock the crosshair to the data point being hovered
|
||||
myFlot.lockCrosshair({ x: item.datapoint[0], y: item.datapoint[1] });
|
||||
}
|
||||
else {
|
||||
// Return normal crosshair operation
|
||||
myFlot.unlockCrosshair();
|
||||
}
|
||||
});
|
||||
|
||||
- unlockCrosshair()
|
||||
|
||||
Free the crosshair to move again after locking it.

/*
|
||||
Flot plugin for computing bottoms for filled line and bar charts.
|
||||
|
||||
The case: you've got two series that you want to fill the area
|
||||
between. In Flot terms, you need to use one as the fill bottom of the
|
||||
other. You can specify the bottom of each data point as the third
|
||||
coordinate manually, or you can use this plugin to compute it for you.
|
||||
|
||||
In order to name the other series, you need to give it an id, like this
|
||||
|
||||
var dataset = [
|
||||
{ data: [ ... ], id: "foo" } , // use default bottom
|
||||
{ data: [ ... ], fillBetween: "foo" }, // use first dataset as bottom
|
||||
];
|
||||
|
||||
$.plot($("#placeholder"), dataset, { line: { show: true, fill: true }});
|
||||
|
||||
As a convenience, if the id given is a number that doesn't appear as
|
||||
an id in the series, it is interpreted as the index in the array
|
||||
instead (so fillBetween: 0 can also mean the first series).
|
||||
|
||||
Internally, the plugin modifies the datapoints in each series. For
|
||||
line series, extra data points might be inserted through
|
||||
interpolation. Note that at points where the bottom line is not
|
||||
defined (due to a null point or start/end of line), the current line
|
||||
will show a gap too. The algorithm comes from the jquery.flot.stack.js
|
||||
plugin, possibly some code could be shared.

/*
|
||||
Flot plugin for plotting images, e.g. useful for putting ticks on a
|
||||
prerendered complex visualization.
|
||||
|
||||
The data syntax is [[image, x1, y1, x2, y2], ...] where (x1, y1) and
|
||||
(x2, y2) are where you intend the two opposite corners of the image to
|
||||
end up in the plot. Image must be a fully loaded Javascript image (you
|
||||
can make one with new Image()). If the image is not complete, it's
|
||||
skipped when plotting.
|
||||
|
||||
There are two helpers included for retrieving images. The easiest work
|
||||
the way that you put in URLs instead of images in the data (like
|
||||
["myimage.png", 0, 0, 10, 10]), then call $.plot.image.loadData(data,
|
||||
options, callback) where data and options are the same as you pass in
|
||||
to $.plot. This loads the images, replaces the URLs in the data with
|
||||
the corresponding images and calls "callback" when all images are
|
||||
loaded (or failed loading). In the callback, you can then call $.plot
|
||||
with the data set. See the included example.
|
||||
|
||||
A more low-level helper, $.plot.image.load(urls, callback) is also
|
||||
included. Given a list of URLs, it calls callback with an object
|
||||
mapping from URL to Image object when all images are loaded or have
|
||||
failed loading.
|
||||
|
||||
Options for the plugin are
|
||||
|
||||
series: {
|
||||
images: {
|
||||
show: boolean
|
||||
anchor: "corner" or "center"
|
||||
alpha: [0,1]
|
||||
}
|
||||
}
|
||||
|
||||
which can be specified for a specific series
|
||||
|
||||
$.plot($("#placeholder"), [{ data: [ ... ], images: { ... } ])
|
||||
|
||||
Note that because the data format is different from usual data points,
|
||||
you can't use images with anything else in a specific data series.
|
||||
|
||||
Setting "anchor" to "center" causes the pixels in the image to be
|
||||
anchored at the corner pixel centers inside of at the pixel corners,
|
||||
effectively letting half a pixel stick out to each side in the plot.
|
||||
|
||||
|
||||
A possible future direction could be support for tiling for large
|
||||
images (like Google Maps).

/*
|
||||
Flot plugin for adding panning and zooming capabilities to a plot.
|
||||
|
||||
The default behaviour is double click and scrollwheel up/down to zoom
|
||||
in, drag to pan. The plugin defines plot.zoom({ center }),
|
||||
plot.zoomOut() and plot.pan(offset) so you easily can add custom
|
||||
controls. It also fires a "plotpan" and "plotzoom" event when
|
||||
something happens, useful for synchronizing plots.
|
||||
|
||||
Options:
|
||||
|
||||
zoom: {
|
||||
interactive: false
|
||||
trigger: "dblclick" // or "click" for single click
|
||||
amount: 1.5 // 2 = 200% (zoom in), 0.5 = 50% (zoom out)
|
||||
}
|
||||
|
||||
pan: {
|
||||
interactive: false
|
||||
cursor: "move" // CSS mouse cursor value used when dragging, e.g. "pointer"
|
||||
frameRate: 20
|
||||
}
|
||||
|
||||
xaxis, yaxis, x2axis, y2axis: {
|
||||
zoomRange: null // or [number, number] (min range, max range) or false
|
||||
panRange: null // or [number, number] (min, max) or false
|
||||
}
|
||||
|
||||
"interactive" enables the built-in drag/click behaviour. If you enable
|
||||
interactive for pan, then you'll have a basic plot that supports
|
||||
moving around; the same for zoom.
|
||||
|
||||
"amount" specifies the default amount to zoom in (so 1.5 = 150%)
|
||||
relative to the current viewport.
|
||||
|
||||
"cursor" is a standard CSS mouse cursor string used for visual
|
||||
feedback to the user when dragging.
|
||||
|
||||
"frameRate" specifies the maximum number of times per second the plot
|
||||
will update itself while the user is panning around on it (set to null
|
||||
to disable intermediate pans, the plot will then not update until the
|
||||
mouse button is released).
|
||||
|
||||
"zoomRange" is the interval in which zooming can happen, e.g. with
|
||||
zoomRange: [1, 100] the zoom will never scale the axis so that the
|
||||
difference between min and max is smaller than 1 or larger than 100.
|
||||
You can set either end to null to ignore, e.g. [1, null]. If you set
|
||||
zoomRange to false, zooming on that axis will be disabled.
|
||||
|
||||
"panRange" confines the panning to stay within a range, e.g. with
|
||||
panRange: [-10, 20] panning stops at -10 in one end and at 20 in the
|
||||
other. Either can be null, e.g. [-10, null]. If you set
|
||||
panRange to false, panning on that axis will be disabled.
|
||||
|
||||
Example API usage:
|
||||
|
||||
plot = $.plot(...);
|
||||
|
||||
// zoom default amount in on the pixel (10, 20)
|
||||
plot.zoom({ center: { left: 10, top: 20 } });
|
||||
|
||||
// zoom out again
|
||||
plot.zoomOut({ center: { left: 10, top: 20 } });
|
||||
|
||||
// zoom 200% in on the pixel (10, 20)
|
||||
plot.zoom({ amount: 2, center: { left: 10, top: 20 } });
|
||||
|
||||
// pan 100 pixels to the left and 20 down
|
||||
plot.pan({ left: -100, top: 20 })
|
||||
|
||||
Here, "center" specifies where the center of the zooming should
|
||||
happen. Note that this is defined in pixel space, not the space of the
|
||||
data points (you can use the p2c helpers on the axes in Flot to help

"amount" is the amount to zoom the viewport relative to the current

range, so 1 is 100% (i.e. no change), 1.5 is 150% (zoom in), 0.7 is
|

70% (zoom out). You can set the default in the options.

/*
|
||||
Flot plugin for rendering pie charts. The plugin assumes the data is
|
||||
coming is as a single data value for each series, and each of those
|
||||
values is a positive value or zero (negative numbers don't make
|
||||
any sense and will cause strange effects). The data values do
|
||||
NOT need to be passed in as percentage values because it
|
||||
internally calculates the total and percentages.
|
||||
|
||||
* Created by Brian Medendorp, June 2009
|
||||
* Updated November 2009 with contributions from: btburnett3, Anthony Aragues and Xavi Ivars
|
||||
|
||||
* Changes:
|
||||
2009-10-22: lineJoin set to round
|
||||
2009-10-23: IE full circle fix, donut
|
||||
2009-11-11: Added basic hover from btburnett3 - does not work in IE, and center is off in Chrome and Opera
|
||||
2009-11-17: Added IE hover capability submitted by Anthony Aragues
|
||||
2009-11-18: Added bug fix submitted by Xavi Ivars (issues with arrays when other JS libraries are included as well)
|
||||
|
||||
|
||||
Available options are:
|
||||
series: {
|
||||
pie: {
|
||||
show: true/false
|
||||
radius: 0-1 for percentage of fullsize, or a specified pixel length, or 'auto'
|
||||
innerRadius: 0-1 for percentage of fullsize or a specified pixel length, for creating a donut effect
|
||||
startAngle: 0-2 factor of PI used for starting angle (in radians) i.e 3/2 starts at the top, 0 and 2 have the same result
|
||||
tilt: 0-1 for percentage to tilt the pie, where 1 is no tilt, and 0 is completely flat (nothing will show)
|
||||
offset: {
|
||||
top: integer value to move the pie up or down
|
||||
left: integer value to move the pie left or right, or 'auto'
|
||||
},
|
||||
stroke: {
|
||||
color: any hexidecimal color value (other formats may or may not work, so best to stick with something like '#FFF')
|
||||
width: integer pixel width of the stroke
|
||||
},
|
||||
label: {
|
||||
show: true/false, or 'auto'
|
||||
formatter: a user-defined function that modifies the text/style of the label text
|
||||
radius: 0-1 for percentage of fullsize, or a specified pixel length
|
||||
background: {
|
||||
color: any hexidecimal color value (other formats may or may not work, so best to stick with something like '#000')
|
||||
opacity: 0-1
|
||||
},
|
||||
threshold: 0-1 for the percentage value at which to hide labels (if they're too small)
|
||||
},
|
||||
combine: {
|
||||
threshold: 0-1 for the percentage value at which to combine slices (if they're too small)
|
||||
color: any hexidecimal color value (other formats may or may not work, so best to stick with something like '#CCC'), if null, the plugin will automatically use the color of the first slice to be combined
|
||||
label: any text value of what the combined slice should be labeled
|
||||
}
|
||||
highlight: {
|
||||
opacity: 0-1
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||

/*
|
||||
Flot plugin for selecting regions.
|
||||
|
||||
The plugin defines the following options:
|
||||
|
||||
selection: {
|
||||
mode: null or "x" or "y" or "xy",
|
||||
color: color
|
||||
}
|
||||
|
||||
Selection support is enabled by setting the mode to one of "x", "y" or
|
||||
"xy". In "x" mode, the user will only be able to specify the x range,
|
||||
similarly for "y" mode. For "xy", the selection becomes a rectangle
|
||||
where both ranges can be specified. "color" is color of the selection
|
||||
(if you need to change the color later on, you can get to it with
|
||||
plot.getOptions().selection.color).
|
||||
|
||||
When selection support is enabled, a "plotselected" event will be
|
||||
emitted on the DOM element you passed into the plot function. The
|
||||
event handler gets a parameter with the ranges selected on the axes,
|
||||
like this:
|
||||
|
||||
placeholder.bind("plotselected", function(event, ranges) {
|
||||
alert("You selected " + ranges.xaxis.from + " to " + ranges.xaxis.to)
|
||||
// similar for yaxis - with multiple axes, the extra ones are in
|
||||
// x2axis, x3axis, ...
|
||||
});
|
||||
|
||||
The "plotselected" event is only fired when the user has finished
|
||||
making the selection. A "plotselecting" event is fired during the
|
||||
process with the same parameters as the "plotselected" event, in case
|
||||
you want to know what's happening while it's happening,
|
||||
|
||||
A "plotunselected" event with no arguments is emitted when the user
|
||||
clicks the mouse to remove the selection.
|
||||
|
||||
The plugin allso adds the following methods to the plot object:
|
||||
|
||||
- setSelection(ranges, preventEvent)
|
||||
|
||||
Set the selection rectangle. The passed in ranges is on the same
|
||||
form as returned in the "plotselected" event. If the selection mode
|
||||
is "x", you should put in either an xaxis range, if the mode is "y"
|
||||
you need to put in an yaxis range and both xaxis and yaxis if the
|
||||
selection mode is "xy", like this:
|
||||
|
||||
setSelection({ xaxis: { from: 0, to: 10 }, yaxis: { from: 40, to: 60 } });
|
||||
|
||||
setSelection will trigger the "plotselected" event when called. If
|
||||
you don't want that to happen, e.g. if you're inside a
|
||||
"plotselected" handler, pass true as the second parameter. If you
|
||||
are using multiple axes, you can specify the ranges on any of those,
|
||||
e.g. as x2axis/x3axis/... instead of xaxis, the plugin picks the
|
||||
first one it sees.
|
||||
|
||||
- clearSelection(preventEvent)
|
||||
|
||||
Clear the selection rectangle. Pass in true to avoid getting a
|
||||
"plotunselected" event.
|
||||
|
||||
- getSelection()
|
||||
|
||||
Returns the current selection in the same format as the
|
||||
"plotselected" event. If there's currently no selection, the
|
||||
function returns null.

/*
|
||||
Flot plugin for stacking data sets, i.e. putting them on top of each
|
||||
other, for accumulative graphs.
|
||||
|
||||
The plugin assumes the data is sorted on x (or y if stacking
|
||||
horizontally). For line charts, it is assumed that if a line has an
|
||||
undefined gap (from a null point), then the line above it should have
|
||||
the same gap - insert zeros instead of "null" if you want another
|
||||
behaviour. This also holds for the start and end of the chart. Note
|
||||
that stacking a mix of positive and negative values in most instances
|
||||
doesn't make sense (so it looks weird).
|
||||
|
||||
Two or more series are stacked when their "stack" attribute is set to
|
||||
the same key (which can be any number or string or just "true"). To
|
||||
specify the default stack, you can set
|
||||
|
||||
series: {
|
||||
stack: null or true or key (number/string)
|
||||
}
|
||||

The stacking order is determined by the order of the data series in
|

the array (later series end up on top of the previous).
|

|

Internally, the plugin modifies the datapoints in each series, adding
|
||||
an offset to the y value. For line series, extra data points are
|
||||
inserted through interpolation. If there's a second y value, it's also
|
||||
adjusted (e.g for bar charts or filled areas).
