Adding Barchart in a chartpanel to a jpanel

Question

I've tried looking for answers to get this but it didn't work properly so here goes my question. I have created a barchart and I want to add this to a jpanel in a java swing application , here is my code for adding chart to the panel,

void addpanel(JFreeChart chart) {

ChartPanel chartpanel = new ChartPanel(chart);
jPanel2.setLayout(new BorderLayout());
jPanel2.add(chartpanel, BorderLayout.CENTER);
chartpanel.setVisible(true);
this.add(jPanel2);
this.pack();
setContentPane(jPanel2);
jPanel2.setVisible(true);

}

but when I run this , chart is not visible in the jpanel2 and it don't give any errors. How can I change this code to make it work ?

I'm guessing that your program extends JFrame or ApplicationFrame.

A ChartPanel is a JPanel , so you don't need jPanel2 at all.
The default layout of JFrame is BorderLayout, and the default location is BorderLayout.CENTER.
Call pack() after you add the contents to the frame.

Call setVisible() last; you shouldn't have to call it for anything inside.

void addPanel(JFreeChart chart) {
    ChartPanel chartPanel = new ChartPanel(chart);
    this.add(chartPanel); //BorderLayout.CENTER
    this.pack();
    this.setVisible(true);
}
