I have been digging around on the web lately to see what I can find that provides a solid, seamless charting ability to WPF and Silverlight. There are a ton of choices out there. After spending a good couple hours last night and some time today I have decided that I am going to go with Visifire. These charts are pretty solid and ridiculously easy to implement. Check out this video for some of the samples they have.
I hope to have some write up how to entries in the near future. I have just completed a few work related projects and I know there are some good samples in all that which are publishable. : )
