How to merge multiple mages?

[gopinath]

I have multiple charts of same size and I want to merge those into a single chart(image) and write into the output stream as single image.
Please help me in doing the task.
Thanks,
Gopi.

If your ChartPanels are inside a JPanel (or other containers in Swing), then you can get a BufferedImage from it using this method:

You could also get a BufferedImage from the ChartPanel for each chart and join these images together as a larger BufferedImage according to their location.
