Package org.pepstock.charba.client.matrix

Class MatrixChart

java.lang.Object

org.pepstock.charba.client.events.HandlerManager

org.pepstock.charba.client.AbstractChart

org.pepstock.charba.client.matrix.MatrixChart

All Implemented Interfaces:

HasAxes, HasCartesianAxes, IsChart, IsDatasetCreator<MatrixDataset>

public final class MatrixChart
extends AbstractChart
implements IsDatasetCreator<MatrixDataset>, HasCartesianAxes

A matrix chart shows magnitude of a phenomenon as color in two dimensions.
The variation in color may be by hue or intensity, giving obvious visual cues to the reader about how the phenomenon is clustered or varies over space.
