When using WinForms or WPF the best choice for a Graphing Control for .NET is probably ZedGraph. Using the MONO framework it is even possible to get the ZedGraph / WinForms application to run on OSX and Linux. However these applications will not look naive on these operating systems.

I have been looking for a long time for a good window toolkit that I could use with the .NET framework across all operating systems. Some time ago qt4dotnet was launched. To make things short, qt4dotnet allows us to use the Qt framework from .NET.  I’ve been using it for about 10 months now and it really seems to deliver the best cross platform experience. This comes at a price of course: you loose a bit on performance and on the other side there are no 3rd Party controls.

Thus I started to port Qwt to C#. A first working prototype is available, but much is left to be done.
