public Object clone()
            throws CloneNotSupportedException
Returns a clone of this instance.
Overrides:
clone in interface AbstractDialLayer
Returns:
A clone.

draw

public void draw(Graphics2D g2,
                 DialPlot plot,
                 Rectangle2D frame,
                 Rectangle2D view)
Draws the frame. This method is called by the DialPlot class, you shouldn't need to call it directly.
Specified by:
draw in interface DialLayer
