public final class Listeners
extends NativeObjectContainer

This is the LISTENER options of DataLabelsPlugin.ID plugin allows to register callback(s) to be notified when an event is detected on a specific label. This option is an object where the property is the type of the event to listen and the value is a callback with a unique context argument.
Charba events need to be enabled in order to get the associated label event working.
If no listener is registered, incoming events are immediately ignored, preventing extra computation such as intersecting label bounding box. That means there should be no performance penalty for configurations that don't use events.
