Oh there is still error, can you please have a look in the program ?
Sorry I am new to java hope someone can solve my problem here...

Q1. Here is where I want to plot graph.

Code:

jButton3.setBounds(new Rectangle(8, 5, 70, 22));
		jButton3.setMargin(new Insets(0, 0, 0, 0));
		jButton3.setText("Plot");
		jButton3.addActionListener(new MainSim_jButton3_actionAdapter(this));

I build a button here, but,

Code:

class MainSim_jButton3_actionAdapter
    implements ActionListener {
    
}

This class is still empty I do not know how to implement the plotting thing...


Q2. Here is where I want to insert the image.

Code:

public void paint(Graphics g) {
        g.setColor(Color.white);
        g.fillRect(0, 0, getWidth(), getHeight());

//Here it draw the white part.

        g.setColor(Color.gray);
        if (fpPoints != null && fpPoints.length > 0) {
            for (int i = 0; i < fpPoints.length; i++) {
                g.drawLine(0, pix_grid * i, getWidth(), pix_grid * i);
            }
            for (int j = 0; j < fpPoints[0].length; j++) {
                g.drawLine(pix_grid * j, 0, pix_grid * j, getHeight());
            }
        }

//And here it draw the gray lines.

        super.paint(g);
        String p = "";
        Color cp = Color.black;
        java.util.Random r = new java.util.Random(10);
        if (highlight != null) {
            for (int i = 0; i < highlight.size(); i++) {
                FpPoint fpp1 = (FpPoint) highlight.get(i);
                if (!p.equalsIgnoreCase(fpp1.getFPRss())) {
                    //g.setColor(new Color((int)(Math.random()*2)*255, (int)(Math.random()*2)*255, (int)(Math.random()*2)*255));
                    g.setColor(new Color( (int) (r.nextFloat() * 2) * 255, (int) (r.nextFloat() * 2) * 255, (int) (r.nextFloat() * 2) * 255));
                    if (g.getColor().equals(Color.white)) {
                        g.setColor(Color.gray);
                    }
                    p = fpp1.getFPRss();
                }
                //g.fillOval(MainSim.m2pixel(fpp1.getPointYm()) - 4, MainSim.m2pixel(fpp1.getPointXm()) - 4, 8, 8);
                g.fillOval(MainSim.m2pixel(fpp1.getPointYm()) - pix_grid / 2, MainSim.m2pixel(fpp1.getPointXm()) - pix_grid / 2, pix_grid, pix_grid);
            }
        }

        if ( apsdata != null ){
            for ( int i = 0 ; i < apsdata.size() ; i ++){
                ApsData ad = (ApsData) apsdata.get(i);
                g.setColor(Color.black);
                g.fillRect(MainSim.m2pixel(ad.getXm()), MainSim.m2pixel(ad.getYm()), 26, 16);
                g.setColor(Color.white);
                g.drawString(String.valueOf(ad.getRssiAvg()), MainSim.m2pixel(ad.getXm())+3, MainSim.m2pixel(ad.getYm()) + 13);
            }
        }
    }
