Class ChartRenderingInfo

java.lang.Object
org.jfree.chart.ChartRenderingInfo
All Implemented Interfaces:
Serializable, Cloneable
public class ChartRenderingInfo
extends Object
implements Cloneable, Serializable
A structure for storing rendering information from one call to the JFreeChart.draw() method.

An instance of the JFreeChart class can draw itself within an arbitrary rectangle on any Graphics2D. It is assumed that client code will sometimes render the same chart in more than one view, so the JFreeChart instance does not retain any information about its rendered dimensions. This information can be useful sometimes, so you have the option to collect the information at each call to JFreeChart.draw(), by passing an instance of this ChartRenderingInfo class.
