Charting Library for Windows Phone 7 with Zooming & Panning?

I'm looking for a Silverlight charting library to use in my Windows Phone 7 project to visualize 50-100 data points. I'd like the series to be zoomable and pannable and be able to attach to these events.

I've so far looked at the Silverlight Toolkit for WP7开发者_C百科, however it seems it does not support zooming or panning at all.

Is there any component out there I could use for this? Seems like a pretty basic requirement for a charting library on the phone, yet I've failed to find any.

The charting controls from VisiBlox support WP7 are free and come highly recommended.

Update:
With surprising coincidence, this video demonstrating functionality has just been posted.
