Specified by:

getPassCount in interface XYItemRenderer

Returns:

The pass count.

getPlot

public XYPlot getPlot()

Returns the plot that the renderer is assigned to.

Specified by:

getPlot in interface XYItemRenderer

Returns:

The plot (possibly null).

setPlot

Sets the plot that the renderer is assigned to.

Specified by:

setPlot in interface XYItemRenderer

Parameters:

plot - the plot (null permitted).

initialise

public XYItemRendererState initialise(java.awt.Graphics2D g2,
                                      java.awt.geom.Rectangle2D dataArea,
                                      XYPlot plot,
