* Make parseTime private
* start on fixing time scale
* Reimplement existing functionality
* Tidy tests
* Fix labels for non-linearly sized units
Months, quarters and years have non-constant numbers of seconds. A scale that's linear WRT milliseconds produces incorrect tick labels due to the label formatting losing precision (eg year labels lose month and day so a label of 2016-12-32 displays as 2016 instead of 2017).
* Re-implement tick generation
As in v2.5
* Fixed issue, that category scale shows data points misplaced. See #4060
* Cleaned code
* Fixed Irregular whitespace
* Fixed error in case value is undefined
* Verified that no error is thrown in case value === null
Radar chart position is not center horizontally with v2.5.0.
Right and left of `furthestLimits` would be switched wrongly on
this refactoring commit.

* Undo fix for #3585 since it has broken the stacked bar charts when the axis has a user defined minimum value.
* When a value of 0 is requested for a vertical logarithmic axis, return the bottom point
The `fill` option now accepts the index of the target dataset (number) or a string starting by "+" or "-" followed by a number representing the dataset index relative to the current one (e.g. `fill: "-2"` on dataset at index 3 will fill to dataset at index 1). It's also possible to "propagate" the filling to the target of an hidden dataset (`options.plugins.filler.propagate`). Fill boundaries `zero`, `top` and `bottom` have been deprecated and replaced by `origin`, `start` and `end`.
Implementation has been moved out of the line element into a new plugin (`src/plugins/plugin.filler.js`) and does not rely anymore on the deprecated model `scaleTop`, `scaleBottom` and `scaleZero` values. Drawing Bézier splines has been refactored in the canvas helpers (note that `Chart.helpers.canvas` is now an alias of `Chart.canvasHelpers`).
Add 3 new examples and extend utils with a pseudo-random number generator that can be initialized with `srand`. That makes possible to design examples starting always with the same initial data.
Prevent attempt to remove the legend or title layout items if they haven't been created but also check if the item to remove is registered with the layout manager to avoid removing the wrong box `splice(-1, 1)`. Add ids to the legend and title plugins to allow to fully disable them (`options: {plugins: {legend: false, title: false}}`).
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.
If a value is set on the model after `pivot()` has been called, the view wasn't initialized and the animation started from 0. Now, `_start` and incomplete `_view` are initialized to the model value during the transition (no initial implicit transition).
Also remove exception handling when animating a string (color), which is faster when string are not valid colors (e.g. tooltip position). It requires to update `chartjs-color` to version 2.1.0.
In order to take full advantage of the new plugin hooks called before and after a dataset is drawn, all drawing operations must happen on stable meta data, so make sure that transitions are performed before.
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`).
Move base platform definition and logic in src/platform/platform.js and simplify the browser -> Chart.js event mapping by listing only different naming then fallback to the native type.
Replace `createEvent` by `add/removeEventListener` methods which dispatch Chart.js IEvent objects instead of native events. Move `add/removeResizeListener` implementation into the DOM platform which is now accessible via `platform.add/removeEventListener(chart, 'resize', listener)`.
Finally, remove `bindEvent` and `unbindEvent` from the helpers since the implementation is specific to the chart controller (and should be private).
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
Fix bar draw issue.
1. `Chart.elements.Rectangle.draw` function supports both horizontal and vertical bar.
2. Corrected bar position at minus.
3. Adjust bar size when `borderWidth` is set.
4. Adjust bar size when `borderSkipped` is set.
5. Adjust `borderWidth` with value near 0(base).
6. Update test.
Plugins can now be declared in the chart `config.plugins` array and will only be applied to the associated chart(s), after the globally registered plugins. Plugin specific options are now scoped under the `config.options.plugins` options. Hooks now receive the chart instance as first argument and the plugin options as last argument.
