Interface LeaveEventHandler

All Known Implementing Classes:

AbstractEventHandler, DataLabelsPointerHandler, DataLabelsSelectionHandler

public interface LeaveEventHandler

Callback interface of DataLabelsPlugin.ID plugin to manage LEAVE events on labels.
Charba events need to be enabled in order to get the associated label event working.
If the callback explicitly returns true, the label is updated with the new context and the chart re-rendered. This allows to implement visual interactions with labels such as highlight, selection, etc.
