public static final double DEFAULT_ITEM_MARGIN
The default item margin percentage.

See Also:
Constant Field Values

itemMargin

private double itemMargin
The margin between items within a category.

maxItemWidth

private double maxItemWidth
The maximum item width as a percentage of the available space.

Constructor Detail

LevelRenderer

public LevelRenderer()
Creates a new renderer with default settings.

Method Detail

getItemMargin

public double getItemMargin()
Returns the item margin.

setItemMargin

public void setItemMargin(double percent)
Sets the item margin. The value is expressed as a percentage of the available width for plotting all the bars, with the resulting amount to be distributed between all the bars evenly.

getMaxItemWidth

public double getMaxItemWidth()
Returns the maximum width, as a percentage of the available drawing space.

setMaxItemWidth

public void setMaxItemWidth(double percent)
Sets the maximum item width, which is specified as a percentage of the available space for all items, and sends a org.jfree.chart.event.RendererChangeEvent to all registered listeners.

initialise

public CategoryItemRendererState initialise(java.awt.Graphics2D g2,
                                            java.awt.geom.Rectangle2D dataArea,
