Mar 27, 2012 at 9:51 AM

Hello All,
                 I have  seen simulation sample and I am creating a graph some what like that.But I want to go a step ahead.

I want to add button below the graph which will show me old data(kinf of like rewind and forward buttons) set by some time since the x-axis is time bound axes..

I hope I am clear 

 

Any Sugesstions...

Thanks in advance
