public class ChartElement
extends AbstractReadOnlyPoint

Calling some methods on your chart instance passing an argument of an event, will return the elements at the event position.
The elements are mapped by this object.
This is the CHART.JS item with all needed info about a data element, used to draw the chart.
This is the base element created by CHART.JS which is extended by the controllers to manage own elements.
