Class crw.data2.GraphSet 

java.lang.Object
   |
   +----crw.data2.GraphSet
public class GraphSet
extends Object
Represents a graphical unit on Canvas, consisting of x-axis, y-axis, x-conversion and y-conversion factors, and one or more Data2 objects. The init() method should be called henever changes occur to affect the axis scaling or data conversion behavior. The draw(Graphics g) should be called whenever changes occur in physical Data or re-plot is made necessary. Otherwise (no changes in data or axis), use an Image object to hold the plot and use Graphics.drawImage().
