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.

Parameters:

entities - an entity collection (null permitted).

Method Details

getChartArea

public Rectangle2D getChartArea()

Returns the area in which the chart was drawn.

Returns:

The area in which the chart was drawn.

setChartArea

public void setChartArea(Rectangle2D area)

Sets the area in which the chart was drawn.

Parameters:

area - the chart area.

getEntityCollection

public EntityCollection getEntityCollection()

Returns the collection of entities maintained by this instance.

Returns:

The entity collection (possibly null).

setEntityCollection

public void setEntityCollection(EntityCollection entities)

Sets the entity collection.

Parameters:

entities - the entity collection (null permitted).

• getEntityCollection()

clear

public void clear()

Clears the information recorded by this object.

getPlotInfo

public PlotRenderingInfo getPlotInfo()

Returns the rendering info for the chart's plot.

Returns:

The rendering info for the plot.

equals

public boolean equals(Object obj)

Tests this object for equality with an arbitrary object.

Overrides:

equals in class Object

Parameters:

obj - the object to test against (null permitted).

Returns:

A boolean.
