problem in displaying chart in swing application.

[anamika1977]

Hi,

I am writing a swing application to show the charts based on some user selection. But when I try to draw chart and display on button click it is not showing can someone help.

new DataAnalysisTool("Demo");
}

public DataAnalysisTool(final String title) {
super(title);
initComponents();
}

I'd say: Learn how to use LayoutManagers.

Your code removes all layout managers from all panels and then you do not set a size (using setSize(..) as setPreferredSize is a hint for the layout manager you already killed).

Else, if you insist on not using a layout manager, then at least compute the layout properly

Have fun,

I have used LayoutManagers but the problem is still here!

ChartPanel bar_panel = new ChartPanel(mychart);
Chart_Panel.add(bar_panel);
Chart_Panel.repaint(); - this doesn't work
//getFrame().pack(); - this does work , but the main frame/window/ is resizing each time

Chart_Panel has BoxLayoutManager. Why repaint() method doesn't work?
