public class XYGraph
extends java.awt.Canvas
implements InterfaceProperties, java.lang.Cloneable

The XYGraph class allows Y values to be plotted against X. The Y values can be scaled against the left axis (Y1) or the right axis (Y2) allowing for multiple plots with different scaling. There are numerous other variables that can be configured at design time for scaling and display of the plot. The XYGraph instantiates vipratech.beans.standardbeans.Trace objects to draw the plot lines on the graph.

The YXGraph receives data using property change events. There is a channel1(PropertyChangeEvent event) method and a channel2(PropertyChange event) method for writing either a single point or a Vector of up to 5 points against a Y axis scale. Poinrs are described vipratech.beans.standardbeans.resources.PointFloat.java.
