Class PolarAreaChart

java.lang.Object

org.pepstock.charba.client.events.HandlerManager

org.pepstock.charba.client.AbstractChart

org.pepstock.charba.client.PolarAreaChart

All Implemented Interfaces:

HasAxes, HasRadialAxis, IsChart, IsDatasetCreator<PolarAreaDataset>

public class PolarAreaChart
extends AbstractChart
implements IsDatasetCreator<PolarAreaDataset>, HasRadialAxis

POLAR AREA chart implementation.
Polar area charts are similar to pie charts, but each segment has the same angle - the radius of the segment differs depending on the value.
This type of chart is often useful when we want to show a comparison data similar to a pie chart, but also show a scale of values for context.
