Two Charts in subreport - how to bind one chart programatically

I have a Report which have a subreport link "View". On clicking "View" want to show two charts. I have already created one chart and set the link source to that chart and it is working fine. Now I want to show the another chart on this same report. This second chart needs some custom coding so i want it to be bind it with database stored procedure. Where do I need to do the coding - in my windows form where I have a crystal report viewer control or can i bind the chart with sp which expects parameters. Any advise would be appreciated.

I am using crystal report for visual studio 2013 in vs2010 c# windows application.
