Hi Experts,

I have developed an application and in my main menu I have a choice to graph data.
I am using JFreeChart library to develop graphs.
Everything is OK. I can get a chart but it is in a separate Chart panel and when I close the ChartPanel it also closes my whole application. What can I do ?

I want to be able to put the graph in my application and be able to close the graph without closinh my application

Here is part of my code when I create the Chart panel :


final ChartPanel chartPanel = new ChartPanel(chart);
chartPanel.setPreferredSize(new java.awt.Dimension(800, 400));
setContentPane(chartPanel);


Do I have to include this code ?

chartPanel.setDefaultCloseOperation(ApplicationFrame.DISPOSE_ON_CLOSE);

My Listener is in my main application class but my ChartDemo class where I create my ChartPanel is in another class and package:

class MyChartListener extends AbstractAction{
           
                                     
                     //display message dialog when user selects Comments ...
                        public void actionPerformed( ActionEvent event )
                        {
                              
                        final HighLowChartDemo chrt = new HighLowChartDemo("eurodollars","Eurodollars Daily",quotes);
                      chrt.pack();
                      RefineryUtilities.centerFrameOnScreen(chrt);
                      chrt.setVisible(true);
                      setDefaultCloseOperation(ApplicationFrame.DISPOSE_ON_CLOSE);

Try

chrt.setDefaultCloseOperation(ApplicationFrame.DISPOSE_ON_CLOSE);

OK. Try setting it to

chrt.setDefaultCloseOperation(ApplicationFrame.DO_NOTHING_ON_CLOSE);

Maybe I should include the ChartDemo class in my my application class and create the ChartPanel inside that class ?

I personally would make the container holding the chart a JDialog, not a JFrame

I solved my problem in changing extends AplicationFrame by extends Frame in my ChartDemo class
