Two problem for my rssi calculation program

[iamchoilan]

I have downloaded a program, which can calculate rssi signal on a grid sheet.

1. I want to build a button, when I press the button, it pop up another window which show a graph on the data the program just calculated.

Can this be done ?

2. I want to insert a image to be the background of the grids, instead of that piece of white sheet, can this be done ?

Yes this can be done, have you ever used paintcomponent before.

Sorry I have not used this before, as I am new to java hope someone can solve my problem here...

Q1. Here is where I want to plot graph.

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,

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.

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);
            }
        }
    }

make an array of your plots and then just iterate through it and plot them as g.drawLine(xvalue of the first one, yValue of the first one, xValue of the next one, yValue of the second one). The hardest part of this is to figure out what the x and y's are.
