import java.awt.event.*;
import java.awt.*;
import javax.swing.SwingUtilities;
import javax.swing.JPopupMenu;
import javax.swing.JMenuItem;
public class MyChart extends Frame  {
     final Draw panel;
     public MyChart(){     
          addWindowListener(new WindowAdapter()     {     
               public void windowClosing(WindowEvent ev)           
               dispose();               
               System.exit(0);
          setBounds(1,1,670,450);     
          panel = new Draw();     
          add(panel);          
          setVisible(true);
          MouseListener ml = new MouseAdapter() {
            public void mousePressed(MouseEvent e) {
               if (SwingUtilities.isRightMouseButton(e)) {
                 Point p = e.getPoint();
                 System.out.println("Mouse pressed");
            }//mousePressed
            public void mouseReleased(MouseEvent e) {
              if (SwingUtilities.isRightMouseButton(e)) {
                    Point p = e.getPoint();
                    MyPopupMenu jPopupMenu1 = new MyPopupMenu();
                    jPopupMenu1.show(panel, p.x, p.y);
                    System.out.println("Mouse released");
            }//mouseReleased
          };//mouseListener
          panel.addMouseListener(ml);
     public class Draw extends Panel{     
          int xt[] = {1,1,1,0,1,1,1,1,0,1,1,1,1,0,1,1};     
          int yv[] = {40,15,30,90,105,128,120,98,199,250,269,203,90,210,200,145};          
          int sx = 40;     
          int sy = 30;     
          public Draw(){     
               super();     
               setBackground(Color.pink);
          public void paint(Graphics g){      
               g.setColor(Color.white);     
               for (int i=0; i < 21; i++)     {          
                    g.setColor(Color.white);          
                    g.drawLine(i*30+sx,sy,i*30+sx,sy*10);          
                    g.setColor(Color.blue);          
                    g.drawString(""+i*30,i*sy+sy+2,30*10+30/2);     
               for (int i=0; i < 10; i++)     {          
                    g.setColor(Color.lightGray);          
                    g.drawLine(sx,i*30+sy,20*30+sx,i*30+sy);          
                    g.setColor(Color.blue);          
                    g.drawString(""+i*30,10,i*sy+sy+2);     
               g.setColor(Color.black);     
               for (int i=0; i < xt.length-1; i++)     {          
                    if (xt[ i ] == 1)          
                         g.drawLine(i*30+sx,yv[ i ]+sy,(i+1)*30+sx,yv[ i+1 ]+sy);     
          public void update(Graphics g){     
               paint(g);
     public class MyPopupMenu extends JPopupMenu {
          JMenuItem menuItem, menuItem2;
          public MyPopupMenu() {
                    menuItem = new JMenuItem("Print chart");
                    menuItem.addActionListener(new ActionListener() {
                      public void actionPerformed(ActionEvent e) {
                        System.out.println("Printing...");
                    menuItem2 = new JMenuItem("Convert to pdf");
                    menuItem2.addActionListener(new ActionListener() {
                      public void actionPerformed(ActionEvent e) {
                        System.out.println("Converting...");
                    add(menuItem);
                    add(menuItem2);
     public static void main(String[] args ) {     
          new MyChart();
}

I wrote a document a while back describing how to use JFreeChart and iText to generate charts in PDF format. You can download it from the JFreeChart project page on SourceForge:
http://sourceforge.net/projects/jfreechart
Look in the 'Files' section under 'Documentation' for a file called 'jfreechart2pdf-v2.pdf'. It should give you some pointers.
