    Post How to use Jpanel

    Hi pple,
    how can i add components to a jpanel that i already created in netbeans?
    I created a simple graph and i want the grph to display on the jpanel. How do i make it appear?
    here is my code
    Java Code:
    public class XYGraph extends javax.swing.JFrame {
    public XYGraph() {
    final XYSeries series = new XYSeries("Xenon Poisoning");
    series.add(0, 400.2);
    series.add(1.0, 294.1);
    final XYSeriesCollection dataset = new XYSeriesCollection(series);
    JFreeChart chart = null;
    chart  = ChartFactory.createXYLineChart("Xenon Concentration and Poisoning",
            "Time(Hrs)", "Power Level(%)",(XYSeriesCollection) dataset, PlotOrientation.VERTICAL, true, true, false);
    // create and display a frame...
    ChartPanel CP = new ChartPanel(chart);
        /** Creates new form XYGraph */
        /** This method is called from within the constructor to
         * initialize the form.
         * WARNING: Do NOT modify this code. The content of this method is
         * always regenerated by the Form Editor.
        * @param args the command line arguments
        public static void main(String args[]) {
            java.awt.EventQueue.invokeLater(new Runnable() {
                public void run() {
                    new XYGraph().setVisible(true);
        // Variables declaration - do not modify
        private javax.swing.JPanel jPanel1;
        // End of variables declaration
    your response will be highly appreciated
