public class Chart2D

extends java.awt.Panel

implements java.io.Externalizable

This class implements the 2 dimensional series charting that allows the data to be displayed in a line, bar or a pie shape. Visual tools like these allow the data to be piped in through other tools like SQL Result Set or a user defined data set.
