- allow options to be updated in-place or as a new object
- re-merge new options and rebuild scales & tooltips
- preserve reference to old scale if id/type not changed
- related tests and new sample also added.
- update document about options update
- update doc and example
Inject the GA tracking snippet for all samples, including the index page. Also update README.md badges using the shields.io service for consistency with flat-square style and cache, and add release badges to the installation documentation page.
New `options.resolve` helper that determines the final value to use from an array of input values (fallback) and a given context and/or index. For now, only the bubble chart support scriptable options, see documentation for details.
Add scriptable options documentation and update the bubble chart dataset properties table with their scriptable and indexable capabilities and default values. Also move point style description under the element configuration section.
Add a new `offset` option to scales to add extra space at edges and remove the `includeOffset` argument from `getPixelForValue()` and `getPixelForTick()`. The bar controller now automatically calculates the bar width to avoid overlaps. When `offsetGridLines` is true, grid lines move to the left by one half of the tick interval, and labels don't move.
For time series charts it may make more sense to specify the horizontal axis using the variable `t`. This change will make it much easier to use the time scale with the financial chart, which takes in the data points `{t, o, h, l, c}`.
The title plugin and scale title now accept lineHeight specified using unitless value (1.4), length ('1.4em' or '12px'), percentage ('200%') or keyword ('normal' === 1.2). The line height parsing has been refactored under the 'Chart.helpers.options' namespace. Also fix incorrect text positioning in the title plugin.

* Fix relative links in documentation of configurations
* Fix relative link of 'Time Units'
* Fix relative links for chart types documentations
* Fix the release version link in developers/plugins
See discussion in the issue for context and possible approaches.
When invoking update() inside an event handler, such as onHover,
`options.hover.animationDuration` was not being respected. Given that
some use cases may require additional animation properties for the
manual update call, this commit changes that method signature to accept
a configuration object.
This object provides backwards compatibility with duration and lazy
properties, and also introduces the easing property so that the event
animation is different from the global one.
Add tests that guarantee that when update is called manually with
arguments, it properly builds the _bufferedRequest or calls render with
the proper arguments.
It includes test cases for when update is called with legacy arguments
(duration and lazy) instead of the config object.
.update() documentation was previously updated but .render() was left
out. Since the backwards compatible change was also made to render(),
this commit adds documentation for it.
Make sure to explain responsiveness limitations with CANVAS elements and how to correctly setup a responsive chart using a dedicated and relatively positioned div wrapper.
* Adds step-after functionality, true defaults to step-before
* Update stepped line sample to include all variations of steppedLine configurations
* Update documentation on steppedLine values
* Add tests for new steppedLine values 'before' and 'after'
* respect new scale option 'order' when ordering scales
* scale service - respect new weight scale option for axes ordering
* added test for scale ordering by weight
* removed trailing spaces from layout weight scale order test
Coverage data are now generated by running `gulp unittest` with the `--coverage` argument: unit tests are then executed a single time on Travis. The gulp `coverage` task has been removed and `karma.coverage.conf.ci.js` merged into `karma.conf.ci.js`.
Update documentation with gulp commands (and remove them from `README.md`) and remove unused `config.jshintrc` (oversight from #3256). Delete `thankyou.md` which has been merged into `README.md`.
gridLines.circular is a new option that toggles circular lines. This allows radar charts with circular lines #3082
pointLabels.display is a new option that toggles the display of point labels.
The existing angleLines.display is used with the new pointLabels.display setting is used to trigger the radar like settings.
This required changing the default polar area config.
Animation callbacks now receives `animationObject` directly with a reference on the associated chart (`animation.chart`), which deprecates `animation.animationObject` and `animation.chartInstance`. Also fix missing `onComplete` animation argument and make sure that an animation object is passed even when animations are disabled.
Chart data can now be entirely replaced using `chart.data = {...}` thanks to the new property setter (instead of using `chart.config.data = {}`). Also update the documentation, as suggested by @ldaguise and @kennethkalmer, with a note about versions prior 2.6.
Make all `before` hooks cancellable (except `beforeInit`), meaning that if any plugin return explicitly `false`, the current action is not performed. Ensure that `init` hooks are called before `update` hooks and add associated calling order unit tests. Deprecate `Chart.PluginBase` in favor of `IPlugin` (no more an inheritable class) and document plugin hooks (also rename `extension` by `hook`).
Refactoring to put browser specific code in a new class, BrowserPlatform.
BrowserPlatform implements IPlatform. Chart.Platform is the constructor for the platform object that is attached to the chart instance.
Plugins are notified about the event using the `onEvent` call. The legend plugin was converted to use onEvent instead of the older private `handleEvent` method.
Wrote test to check that plugins are notified about events
Pass the hover event to the onHover event handler
This makes the behavior of the `onHover` handler consistent with the `onClick` handler:
```
function(event, activeElements) {
var chartInstance = this;
}
```
Add support for creating a chart from the canvas id and prevent exceptions, at construction time, when the given item doesn't provide a valid CanvasRenderingContext2D or when the getContext API is not accessible (e.g. undefined by add-ons to prevent fingerprinting). New jasmine matcher to verify chart validity.
Thanks to the Bower team, we have been able to register the chart.js package name, previously pointing on a dead repository, which make the Bower integration more consistent with the npm one. All other alias still work (Chart.js, chartjs, Chart-js, chartjs-Chart.js).
Add "onHover" to the legend options that will hold a user defined function (default is null) and called when a "mousemove" event is registered on top of a label item, with same parameters as the "onClick" option.
Also introduced logic that determines if the type of event passed to the legend "handleEvent" function is one we can handle. Currently allowing "click" and "mousemove" events. If the event is not one of those we stop the function execution (this is for the sake of reusing the legend hitbox calculations).
When dealing with time-delineated datasets, often we have data for known
intervals of time. For example, we may have a dataset which represents number
of purchases per day:
```json
{
labels: ['2016-01-01', '2016-01-02', '2016-01-03']
datasets: [
{
data: [12, 87, 42]
}
],
'...': '...'
}
```
In this case, Chart.js will attempt to figure out the best interval to display
the data, and could pick `hours` as the unit. However, in this case, we would
prefer to just use the `days` interval since our data's granularity can not be
represented well with `hours`.
To remedy this, this commit adds the `minUnit` option which allows
users to (optionally) specify what the minimum unit they would like
to use.
Change the linter in gulp tasks to be consistent with Code Climate results which are based on ESLint using .eslintrc options. However, defaults Code Climate rules are too strict, so turn as warnings the 'complexity' and 'max-statements' rules (other errors has been fixed). Note that the Gulp task name has been changed for `gulp lint`.
