Hi,
I am drawing line charts for a set of points.These points will be selected from the .aspx page.Then there is a button which when clicked will generate report.The number of charts displayed will be equal to the number of selected points.Each of these line charts have trendlines too.The user specifies an upper and lower limit for the perchange in the bending of the trendline.Formula for it is is (slope of trendline * no of days) / intercept of trendline * 100.Now if the calculated value is not within specified range I need to display a label with the corresponding message.So this message has to be displayed for each of the points when we select the point from the group tree on the left.At present i have the line charts displayed as i click each point in the group tree.

Please help me out.Any help is greatly appreciated.
Thanks,
Varsha
