Hi all,
I need to develop this screen using the jfree chart ,since I am new to the Jfree chart I need help as to how I to get started and how I will draw two graphs .
If someone can provide me with some demo code that will be really helpful.The screenshot is on this url.
Thanks.

You won't be able to produce this with JFreeChart unless you're prepared to write a custom dataset class (based on the IntervalXYDataset interface) and a custom renderer (something along the lines of XYBarRenderer, but taking into account the variations in the y-value range also).

I think it is doable, but if you are new to JFreeChart maybe it is not so easy.

does the developer guide has similar demo chart programs.

No. As I said, to create a chart like that you'd need a custom dataset and a custom renderer, and those haven't been written by anyone. If I had more time, I'd write one for you and include it in JFreeChart...

I think there is a possible workaround. The vertical bars are not a problem and the horizontal footer could be an annotation. Just an idea...
