thanx that worked.. but what about interactivity i want to add interactivity to graphs. (like on mousehover showing the value at that point and in pie chart seperating the area of that regoin from rest).
can we do that.?

You can set tooltips on the chart series properties dialog - the expression for tooltips can be specified on the same tab as the x/y value expression.

Solution 1

Could not load file or assembly 'System.Web.Extensions, Version=3.5.0.0,
It simply means that System.Web.Extensions V3.5 is missing and is required by your project application. Find the exact same version of the assembly and place it in application bin folder or GAC of the server.
