* 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'
* 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
Add window scroll position to tooltip position calculation so they show up in the intended place instead of potentially off-screen! Moved tooltips inside the canvas parent container since they are being positioned in terms of its location
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.
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.
I added new samples to explain behaviour and modified all samples to have consistent styling. In updating the samples,
I removed the use of jQuery and instead use standard methods.
For the custom tooltip samples, I updated the styling to show color boxes like the regular tooltips.
Now that the aspect ratio is correctly handled, fix samples for charts with aspect ratio of 1 which was vertically too large. Also fix the default aspect ratio for radar charts which wasn't applied when creating a chart directly using new Chart(ctx, { type: 'radar' }).
Adds a lot of new information to the docs that will help developers better utilize the entire Chart.js library
List of implemented changes:
- Reverse option for legends (resolves#3102)
- Information about chart resizing (resolves#3023)
- Mixed chart types (resolves#2825) (resolves#2431)
- Chart library comparison table (resolves#2605)
- getDetasetMeta function information (resolves#2521)
- Popular Extensions (resolves#2365)
* Category scale can now read from the xLabels and yLabels properties.
* Update docs with section regarding the data object.
* Add sample file with non numeric Y and fix animations
Samples need to be packaged with built libraries (which one have been removed from the repository), so create a new `gulp package` task to generate a ZIP archive with dist files, samples and the license file. This archive is generated in the ./dist/ folder and will be deployed by Travis along the GH release. Note that the ./dist/ folder is not preserved but merged in the archive root. Also change samples requiring moment.js to load this lib from the CDN instead of the ./node_module folder.
Usage: If a label is an `array` as opposed to a `string` i.e. `[["June","2015"], "July"]` then each element is treated as a seperate line. The appropriate calculations are made to determine the correct height and width, and rotation is still supported.
