|
|
|
|
### Changes ###
|
|
|
|
- Updated example code to avoid encouraging unnecessary re-plots.
|
|
(patch by soenter, pull request #1221)
|
|
|
|
### Bug fixes ###
|
|
|
|
- Added a work-around to disable the allocation of extra space for first and
|
|
last axis ticks, allowing plots to span the full width of their container.
|
|
A proper solution for this bug will be implemented in the 0.9 release.
|
|
(reported by Josh Pigford and andig, issue #1212, pull request #1290)
|
|
|
|
- Fixed a regression introduced in 0.8.1, where the last tick label would
|
|
sometimes wrap rather than extending the plot's offset to create space.
|
|
(reported by Elite Gamer, issue #1283)
|
|
|
|
- Fixed a regression introduced in 0.8.2, where the resize plugin would use
|
|
unexpectedly high amounts of CPU even when idle.
|
|
(reported by tommie, issue #1277, pull request #1289)

### Bug fixes ###
|
|
|
|
- Fixed an unexpected change in behavior that resulted in duplicate tick
|
|
labels when using a plugin, like flot-tickrotor, that overrode tick labels.
|
|
(patch by Mark Cote, pull request #1091)
|
|
|
|
- Fixed a regression from 0.7 where axis labels were given the wrong width,
|
|
causing them to overlap at certain scales and ignore the labelWidth option.
|
|
(patch by Benjamin Gram, pull request #1177)
|
|
|
|
- Fixed a bug where the second axis in an xaxes/yaxes array incorrectly had
|
|
its 'innermost' property set to false or undefined, even if it was on the
|
|
other side of the plot from the first axis. This resulted in the axis bar
|
|
being visible when it shouldn't have been, which was especially obvious
|
|
when the grid had a left/right border width of zero.
|
|
(reported by Teq1, fix researched by ryleyb, issue #1056)
|
|
|
|

|
(reported by Munsifali Rashid, issue #1095)
|
|
|
|

|
|
that the font size of the plot placeholder, which may be very different.

## Flot 0.8.1 ##
|
|
|
|
### Bug fixes ###
|
|
|
|
- Fixed a regression in the time plugin, introduced in 0.8, that caused dates
|
|
to align to the minute rather than to the highest appropriate unit. This
|
|
caused many x-axes in 0.8 to have different ticks than they did in 0.7.
|
|
(reported by Tom Sheppard, patch by Daniel Shapiro, issue #1017, pull
|
|
request #1023)
|
|
|
|
- Fixed a regression in text rendering, introduced in 0.8, that caused axis
|
|
labels with the same text as another label on the same axis to disappear.
|
|
More generally, it's again possible to have the same text in two locations.
|
|
(issue #1032)
|
|
|
|
- Fixed a regression in text rendering, introduced in 0.8, where axis labels
|
|
were no longer assigned an explicit width, and their text could not wrap.
|
|
(reported by sabregreen, issue #1019)
|
|
|
|
- Fixed a regression in the pie plugin, introduced in 0.8, that prevented it
|
|
from accepting data in the format '[[x, y]]'.
|
|
(patch by Nicolas Morel, pull request #1024)
|
|
|
|
- The 'zero' series option and 'autoscale' format option are no longer
|
|
ignored when the series contains a null value.
|
|
(reported by Daniel Shapiro, issue #1033)
|
|
|
|
- Avoid triggering the time-mode plugin exception when there are zero series.
|
|
(reported by Daniel Rothig, patch by Mark Raymond, issue #1016)
|
|
|
|
- When a custom color palette has fewer colors than the default palette, Flot
|
|
no longer fills out the colors with the remainder of the default.
|
|
(patch by goorpy, issue #1031, pull request #1034)
|
|
|
|
- Fixed missing update for bar highlights after a zoom or other redraw.
|
|
(reported by Paolo Valleri, issue #1030)
|
|
|
|
- Fixed compatibility with jQuery versions earlier than 1.7.
|
|
(patch by Lee Willis, issue #1027, pull request #1027)
|
|
|
|
- The mouse wheel no longer scrolls the page when using the navigate plugin.
|
|
(patch by vird, pull request #1020)
|
|
|
|
- Fixed missing semicolons in the core library.

## Flot 0.8.0 ##
|
|
|
|
### API changes ###
|
|
|
|
Support for time series has been moved into a plugin, jquery.flot.time.js.
|
|
This results in less code if time series are not used. The functionality
|
|
remains the same (plus timezone support, as described below); however, the
|
|
plugin must be included if axis.mode is set to "time".
|
|
|
|
When the axis mode is "time", the axis option "timezone" can be set to null,
|
|
"browser", or a particular timezone (e.g. "America/New_York") to control how
|
|
the dates are displayed. If null, the dates are displayed as UTC. If
|
|
"browser", the dates are displayed in the time zone of the user's browser.
|
|
|
|
Date/time formatting has changed and now follows a proper subset of the
|
|
standard strftime specifiers, plus one nonstandard specifier for quarters.
|
|
Additionally, if a strftime function is found in the Date object's prototype,
|
|
it will be used instead of the built-in formatter.
|
|
|
|
Axis tick labels now use the class 'flot-tick-label' instead of 'tickLabel'.
|
|
The text containers for each axis now use the classes 'flot-[x|y]-axis' and
|
|
'flot-[x|y]#-axis' instead of '[x|y]Axis' and '[x|y]#Axis'. For compatibility
|
|
with Flot 0.7 and earlier text will continue to use the old classes as well,
|
|
but they are considered deprecated and will be removed in a future version.
|
|
|
|
In previous versions the axis 'color' option was used to set the color of tick
|
|
marks and their label text. It now controls the color of the axis line, which
|
|
previously could not be changed separately, and continues to act as a default
|
|
for the tick-mark color. The color of tick label text is now set either by
|
|
overriding the 'flot-tick-label' CSS rule or via the axis 'font' option.
|
|
|
|
A new plugin, jquery.flot.canvas.js, allows axis tick labels to be rendered
|
|
directly to the canvas, rather than using HTML elements. This feature can be
|
|
toggled with a simple option, making it easy to create interactive plots in the
|
|
browser using HTML, then re-render them to canvas for export as an image.
|
|
|
|
The plugin tries to remain as faithful as possible to the original HTML render,
|
|
and goes so far as to automatically extract styles from CSS, to avoid having to
|
|
provide a separate set of styles when rendering to canvas. Due to limitations
|
|
of the canvas text API, the plugin cannot reproduce certain features, including
|
|
HTML markup embedded in labels, and advanced text styles such as 'em' units.
|
|
|
|
The plugin requires support for canvas text, which may not be present in some
|
|
older browsers, even if they support the canvas tag itself. To use the plugin
|
|
with these browsers try using a shim such as canvas-text or FlashCanvas.
|
|
|
|
The base and overlay canvas are now using the CSS classes "flot-base" and
|
|
"flot-overlay" to prevent accidental clashes (issue 540).
|
|
|
|

## 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,
|
|
|
|
```js
|
|
{
|
|
xaxis: { ... }, x2axis: { ... },
|
|
yaxis: { ... }, y2axis: { ... }
|
|
}
|
|
```
|
|
|
|
becomes
|
|
|
|
```js
|
|
{
|
|
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:
|
|
|
|
```js
|
|
{ grid: { tickColor: "#000" }}
|
|
```
|
|
|
|
becomes
|
|
|
|
```js
|
|
{ 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:

### 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. (raised by lastthemy, issue 235)
|
|
|
|
Can be disabled by setting the pan.frameRate option to null.
|
|
|
|
- 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.
|
|
|
|

- 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).

## Flot 0.6 ##
|
|
|
|
### API changes ###
|
|
|
|
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.
|
|
|
|
In the global options specified in the $.plot command, "lines", "points",
|
|
"bars" and "shadowSize" have been moved to a sub-object called "series":
|
|
|
|
```js
|
|
$.plot(placeholder, data, { lines: { show: true }})
|
|
```
|
|
|
|
should be changed to
|
|
|
|
```js
|
|
$.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.
|
|
|
|
"plothover" no longer provides the original data point, but instead a
|
|
normalized one, since there may be no corresponding original point.
|
|
|
|
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. (patches from Amaury Chamayou and
|
|
Mike R. Williamson)
|
|
|
|
- Added support for gradient backgrounds for the grid. (based on patch from
|
|
Amaury Chamayou, issue 90)
|
|
|
|
The "setting options" example provides a demonstration.
|
|
|
|
- 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. (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. (reported by nperelman, issue 65)
|
|
|
|
- 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. (reported
|
|
by meyuchas)
|
|
|
|
- Use CSS borders instead of background in legend. (issues 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. (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 ##
|
|
|
|
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).
|
|
|
|
### API changes ###
|
|
|
|
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().
|
|
|
|
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)
|
|
|
|
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).
|
|
|
|
## Changes ##
|
|
|
|
- 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.
|
|
|
|
- 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.
|
|
|
|
- Improved the handling of axis auto-scaling with bars.
|
|
|
|
## Bug fixes ##
|
|
|
|
- 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.
|
|
|
|
- Fixed a bug with multi-line x-axis tick labels. (reported by Luca Ciano,
|
|
IE-fix help by Savage Zhang)
|
|
|
|
- Using the "container" option in legend now overwrites the container element
|
|
instead of just appending to it, fixing the infinite legend bug. (reported
|
|
by several people, fix by Brad Dewey)
|
|
|
|
|
|
|
|
## 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.
|
|
|
|
## Changes ##
|
|
|
|
- Added support for segmented lines. (based on patch from Michael MacDonald)
|
|
|
|
- Added support for ignoring null and bad values. (suggestion from Nick
|
|
Konidaris and joshwaihi)
|
|
|
|
- Added support for changing the border width. (thanks to joebno and safoo)
|
|
|
|
- Label colors can be changed via CSS by selecting the tickLabel class.
|
|
|
|
## Bug fixes ##
|
|
|
|
- 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).
|

## Flot 0.3 ##
|
|
|
|
This is mostly a quick-fix release because jquery.js wasn't included in the
|
|
previous zip/tarball.
|
|
|
|
## Changes ##
|
|
|
|
- Include jquery.js in the 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.

## Bug fixes ##

## Flot 0.2 ##
|
|
|
|
The API should now be fully documented.
|
|
|
|
### API changes ###
|
|
|
|
Moved labelMargin option to grid from x/yaxis.
|
|
|
|
## Changes ##
|
|
|
|
- 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.
|
|
|
|
- Reduced the size of the code. (patch by Guy Fraser)
