Method Detail

dataChanged

public void dataChanged(GraphDataEvent e)

Implementation of GraphDataListener. Application code will not use this method explicitly, it is used internally.

Specified by:

dataChanged in interface GraphDataListener

Specified by:

dataChanged in class CategoryGraph2D

setColor

public final void setColor(int n,
                           java.awt.Color c)

Sets the slice color of the nth slice.

Parameters:

n - the index of the slice.

c - the slice color.

getColor

public final java.awt.Color getColor(int n)

Gets the slice color of the nth slice.

Parameters:

n - the index of the slice.

setBounds

public final void setBounds(int x,
                            int y,
                            int width,
                            int height)

Reshapes the PieChart to the specified bounding box.

Overrides:

setBounds in class java.awt.Component

rescale

protected final void rescale()

Rescales the PieChart.

offscreenPaint

protected void offscreenPaint(java.awt.Graphics g)

Paint the graph.

Specified by:
