Class SankeyChart

java.lang.Object

org.pepstock.charba.client.events.HandlerManager

org.pepstock.charba.client.AbstractChart

org.pepstock.charba.client.sankey.SankeyChart

All Implemented Interfaces:

HasAxes, IsChart, IsDatasetCreator<SankeyDataset>

public final class SankeyChart
extends AbstractChart
implements IsDatasetCreator<SankeyDataset>

Sankey charts are a type of flow diagram in which the width of the arrows is proportional to the flow rate.
Sankey diagrams emphasize the major transfers or flows within a system.
They help locate the most important contributions to a flow.
They often show conserved quantities within defined system boundaries.
