Anyone know of (or written) any decent tutorials on how to make bar charts and pie charts etc in WPF? I thought this would be a fairly common thing to want to do but a quick google search didnt get me much useful stuff. I found a few that you have to pay for, a few that looked awful, and a few that were like full class libraries you had to download and reference in your project, which is not what I want to do.

I'd love to make some nice 3D ones but I'm guessing that is probably going to be quite tricky so I would settle for 2D

Any pointers, links or books much appreciated

Cheers
Chris
