All Implemented Interfaces:

BarRenderer, BarRenderer2D

public class RaisedBarRenderer
extends AbstractBarRenderer
implements BarRenderer2D

A Bar Renderer that makes the bar appear to be raised out of the screen like a candy bar.

This renderer takes account of negative heights. If a negative height is supplied, then the y coordinate and height are adjusted so that the height becomes positive and the shape is paintable.

NOTE: Widths are currently assumed to be positive

Constructor Detail

RaisedBarRenderer

public RaisedBarRenderer()

RaisedBarRenderer

public RaisedBarRenderer(int edgeSize)

Create a RaisedBarRenderer using the supplied edge size

Parameters:

edgeSize - the edge size for the raised effect

Method Detail

getEdgeSize

public int getEdgeSize()

Returns:

the size of the edge effect, in pixels, that gives bars their 'candy bar' appearance

setEdgeSize

public void setEdgeSize(int edgeSize)

Specify the size, in pixels, of the edge effect that gives the raised bars their 'candy bar' appearance. By default, this is 20 pixels, but you may want to set it to a smaller value if you have narrow bars.

Parameters:

edgeSize - the new edge size

renderBar

public Shape renderBar(Graphics2D g,
                       Chart chart,
