Recently, I use WebChart Control for ASP.NET, which supports Linechart, ColumnChart, SmoothlineChart, StackedColumnChart, AREACHART, ScatterChart, StackedareArt, Scatterchart, chart draws, the feature is OK, I am studying it.
It is free, you can download from http://www.carlosag.net/tools/webchart/default.aspx, and some Samples can be referred to, interested friends can try it.
