Free Microsoft Chart Control for .NET 3.5 and .NET 4.0
Finally, Microsoft decided to provide a charting component for .NET Framework! It is called Microsoft Chart Control and it is based on Dundas Chart Control version 5.5. The Microsoft Chart Control is available as separate installation for .NET Framework 3.5 and will be included in .NET Framework 4.0.
Microsoft Chart Control is based on Dundas Chart
Microsoft Chart Control ships for ASP.NET and WindowsForms technologies and according to Alex Gorev's Weblog post: “Microsoft acquired Dundas Data Visualization Intellectual Property in April 2007 and is integrating this technology in different Microsoft products. New Chart and Gauge report items were already released as part of SQL Reporting Services 2008.”
Here is the place you can get more Microsoft Chart Control help from: Microsoft Chart Control Forum. Now let's see how is this better than the Infragistics UltraChart control. :)
