Thanks Manish.but I also Have to show revenue field by default.
another question is , 2 charts should be shown on a button alternatively.
Thanx in advance.
Are you looking for controlling the visibility of two charts using buttons. Please find a sample.
If so then you can also use auto minimize feature or you can keep both the charts in a Container.
I've attached one sample in my previous reply. Please take a look. If you need something else then pls post your QVW with sample or scrambled data. It would help me to provide you a solution you are looking for.
