New Charts

Dataset controllers must implement the following interface.

The following methods may optionally be overridden by derived dataset controllers.

The built in controller types are:

BubbleController
DoughnutController
LineController
PolarAreaController
RadarController
ScatterController

These controllers are also available in the UMD package, directly under . Eg: Chart.BarController.

If you want your new chart type to be statically typed, you must provide a .d.ts TypeScript declaration file. Chart.js provides a way to augment built-in types with user-defined ones, by using the concept of “declaration merging”.

When adding a new chart type, ChartTypeRegistry must contains the declarations for the new type, either by extending an existing entry in or by creating a new one.
