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`).
