Using VerticalBarChartDemo, I have created bar chart. Now I want to print the bar chart. Can some one please give me the sample code to print my garph??

Thanks in advance..

Click on the chart with the right mouse button and select 'Print...', the code that handles this is all in the ChartPanel class.
