JFreeChart Problems

[Dcalladi]

I am trying to use JFreeChart to create charts obviously. JFreeChart come with ChartFrame and ChartPanel.
I have a class to create the chart itself then in another class i have ChartPanel and add that to a normal JPanel this works so far
by using :

        ChartPanel chartsPanels = new ChartPanel(charts);
        GroupLayout mainPanelLayout = new GroupLayout(chartPanel);
        chartPanel.setLayout(mainPanelLayout);
        mainPanelLayout.setAutoCreateContainerGaps(true);
        mainPanelLayout.setAutoCreateGaps(true);
        GroupLayout.SequentialGroup hGroup = mainPanelLayout.createSequentialGroup();
        hGroup.addComponent(chartsPanels);
        mainPanelLayout.setHorizontalGroup(hGroup);
        GroupLayout.SequentialGroup vGroup = mainPanelLayout.createSequentialGroup();
        vGroup.addComponent(chartsPanels);
        mainPanelLayout.setVerticalGroup(vGroup);

my problem is that when i click the button an try to change the chart displaying it won't do anything i can't think it would be about the class that creates the chart it would be the method of displaying.

it won't do anything i can't think it would be about

Are you sure the code is executing? If you don't execute it, it won't do anything.
