This is a program to display a pie chart. I also have a button. But the program I have written, creates two separate frames and one frame is for the pie chart and the other is for the button. How do I put both button and pie chart on the same frame?? Can you please rectify my program.

panel.add(b);

pieDataset.setValue("A", new Integer(10));

pieDataset.setValue("C", new Integer(30));
pieDataset.setValue("D", new Integer(10));
pieDataset.setValue("E", new Integer(20));
pieDataset.setValue("F", new Integer(10));
JFreeChart chart = ChartFactory.createPieChart("Pie Chart using JFreeChart", pieDataset, true,true,true);
ChartFrame frame1=new ChartFrame("Pie Chart",chart);
frame1.add(panel);
frame1.setVisible(true);
frame1.setSize(600,600);
}
}
