Your big problem is using a very old version of the software: VS2005 is 7 years and three versions old. The MS Chart control was (I think) introduced at .NET V3.5, which came in at VS2008.
Have a look here: A flexible charting library for .NET
It includes a version for .NET 1.1 which VS2005 supports, but I would strongly suggest that you need to update your development environment! MS does do free versions of Visual Studio - they are called the Express versions and are available from thier web site directly.
