I am looking for a good charting component compatible with ASP.NET 2.0. I have been comparing and trying various charting controls lately and maybe some of my findings could by also useful for you. I was looking for some control that supports transparent chart caching, saving to files and would easily integrate to existing Asp Net application.I'm looking for something that's capable of generating 2D charts right now, but 3D support would also be welcome. The control should be easy to use but also fully customizable (sounds like a sci-fi huh?).
I have decided not to include samples of generated graphs, as the post would be too long for a blog. There are direct links to example pages for everywhere it was possible.

There are also some free .net charting components available. Though they did not meet my requirements, they could be very useful in some other project.
ZedGraph is a set of classes, written in C#, for creating 2D line and bar graphs of arbitrary datasets. The classes provide a high degree of flexibility -- almost every aspect of the graph can be user-modified. At the same time, usage of the classes is kept simple by providing default values for all of the graph attributes. The classes include code for choosing appropriate scale ranges and step sizes based on the range of data values being plotted. ZedGraph is maintained as an open-source, is fully compatible with Microsoft .NET Framework 2.0 and looks very professional. ZedGraph also provider webcontrol interface, so it could easily be used from ASP.NET 2.0 applications. ZedGraph charting gallery
