Class WCMCrossHairBean

java.lang.Object
  java.awt.Component
      net.sourceforge.webcompmath.draw.Drawable
          net.sourceforge.webcompmath.draw.DrawGeometric
              net.sourceforge.webcompmath.draw.Crosshair
                  net.sourceforge.webcompmath.draw.beans.WCMCrossHairBean

All Implemented Interfaces:

java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, Computable

public class WCMCrossHairBean
extends Crosshair

This bean extends the CrossHair class (which extends DrawGeometric) by adding a convenience setter. If you want to have the crosshair track along a function, set X1 to the independent variable for the function, and then set the YFunction property to a function.
