Java&JFreeChart - How to set a JFreeChart's ChartPanel resize with it's container ( say JPanel )?

Question

I just found that when i add a ChartPanel to a JFrame, the ChartPanel will resize to fit the frame as the JFrame dragged larger or smaller. However, when i add the ChartPane

Answer 1

Try my code and it works fine.

Note that :

I have one frame which contains a panelMain, A panelMain contains a subPanel and a subPanel contains ChartPanel.

frame.setLayout(new BoxLayout(frame.getContentPane(), BoxLayout.Y_AXIS));                      
JPanel panelMain = new JPanel(new GridLayout(0,2));            
ChartPanel chartPanel = createChart();        
JPanel subPanel = new JPanel(new BorderLayout());   
subPanel.setBorder(BorderFactory.createTitledBorder("Consommation"));
subPanel.setPreferredSize(new Dimension(400, 200));    
subPanel.add(chartPanel);   


panelMain.add(subPanel);        
frame.add(panelMain);        
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);

And now when you resize your window application. Your chartPanel will resized automatically. Hope this helps.
