Plotting library for Windows Phone 7 / Silverlight

Question

Is there any plotting control/library for Windows Phone 7 / Silverlight? I want to plot a signal, ideally with the ability to pinch zoom it and pan it (but thats too much to expect probably :)?

Answer 1

Here's a free one, and if you're only plotting one set of data, it's great. Pinch-Zoom on the horizontal axis.
