Program: PlotterAWT

In Program: Plotter , we discussed a series of Plotter classes. The PlotterAWT class shown
in Example 12-12 extends that recipe to provide a “plot preview” service: before being plot-
ted on a (probably slow) plotter, the plot is displayed in an AWT window using the Graphics
drawing primitives.

Example 12-12. PlotterAWT.java
public public class class PlotterAWT PlotterAWT extends extends Plotter {

private private JFrame f ;

private private PCanvas p ;

private

private Graphics g ;
private

private Font font ;
private private FontMetrics fontMetrics ;

PlotterAWT () {
f = new new JFrame ( "Plotter" );

Container cp = f . getContentPane ();
