public interface PlottableGraphics

This interface is implemented by all classes that can paint/print themselves. The property defined by this interface is that the implementor can draw itself on screen or printer based on parameters computed in a previous call to plot(). This minimizes the computational load that takes place when the AWT is drawing the object on screen.
