Release Version 2.5.0 · chartjs/Chart.js · GitHub
Version 2.5 brings some exciting new features to Chart.js. Now, configuration options can be updated at runtime (with some exceptions) just by changing the chart.config.options
object and calling chart.update()
.
More powerful plugins that can be added to an individual chart (instead of globally), but also disabled on a per chart basis. This gives you fine grained control over when plugins interact with your charts. The plugins were changed to support cancelling actions by returning false
from any before*
plugin calls.
Two new extensions have been added: beforeEvent
and afterEvent
, respectively called before and after the chart responds to an input event such as a mousemove
or a click
. The plugin is passed a wrapped version of the event, that implements IEvent
.
Breaking Changes
- #3570 Removed unused
Chart.helpers.cancelAnimFrame
method.
- #3669
onHover
callback now has 3 parameters. The 2nd parameter is the event that triggered the hover. This was done for consistency with the onClick
callback.
Deprecations
- #3819
IPlugin.afterScaleUpdate
: use IPlugin.afterLayout
hook instead.
- #3819 Extending
Chart.PlugingBase
is not anymore required and is strongly discouraged, instead create/register plugins using plain JavaScript objects (see this example).
