Specified by:
dataChanged in class CategoryGraph2D
Parameters:
e - DOCUMENT ME!

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
