I have a gridview that I loop through to get the x and y values of the chart control, and upon the first execution of this code, it looks great. But when the page posts back and it "refreshes" data, the original points on the chart control are still there, as well as the new values.
Is there any way to "delete" all data in the chart control to ensure this doesn't happen? I can't seem to find any resources to help me out with this.
Thanks in advance. :)
