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.
Implemented alignment by major unit in the time scale. This allows showing the first tick of a larger unit like days in a special way and is part of the basis of the time series scale.
Fix onHover event not being triggered
The core controller was looking at the wrong object (options.hover) to
find the function to be called on hover. The function is provided on the
top level options object (options.onHover).
By using the helper function, there's no need to verify if the callback
is defined, as the helper already does that.
Fixes#4296
Add Travis CI task to deploy the docs, samples and dist files to chartjs.github.io for the `release` and `master` branches. A `latest` symbolic links is also created for each folder to the highest version (or `master` if any).
`instanceof HTMLCanvasElement/CanvasRenderingContext2D` fails when the item is inside an iframe or when running in a protected environment. We could guess the types from their toString() value but let's keep things flexible and assume it's a sufficient condition if the item has a context2D which has item as `canvas`.
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'
* Fixed different calculation of scale min and max when dataset contains no values
* Removed trailing spaces
* Added test for correct min/max calculation
* Removed trailing spaces
Merge most of the horizontalBar controller into the bar one but also fix stack groups and bar positioning when scales are stacked or when a min and/or max tick values are explicitly defined. Note that this is a breaking change for derived controllers that rely on the following removed methods: `calculateBarBase`, `calculateBarX`, `calculateBarY`, `calculateBarWidth` and `calculateBarHeight`.
* 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
