Constructor Detail

VerticalBarRenderer

public VerticalBarRenderer()

Creates a new renderer with no tool tip generator and no URL generator.

The defaults (no tool tip or URL generators) have been chosen to minimise the processing required to generate a default chart. If you require tool tips or URLs, then you can easily add the required generators.

VerticalBarRenderer

public VerticalBarRenderer(CategoryToolTipGenerator toolTipGenerator)

Creates a new renderer with the specified tooltip generator but no URL generator.

Parameters:

toolTipGenerator - the tool tip generator.

VerticalBarRenderer

public VerticalBarRenderer(CategoryURLGenerator urlGenerator)

Creates a new renderer with the specified URL generator but no tooltip generator.

Parameters:

urlGenerator - the URL generator.

VerticalBarRenderer

public VerticalBarRenderer(CategoryToolTipGenerator toolTipGenerator,
                           CategoryURLGenerator urlGenerator)

Creates a new renderer with the specified tooltip generator and URL generator.

Parameters:

toolTipGenerator - the tool tip generator.

urlGenerator - the URL generator.

Method Detail

initialise

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