Hi Mikewiese,
Zooming ans Scrolling functionality is one of our development goals for the upcomming Q3 2011 which will be released in the middle of November. Currently it is not available with the Beta version. As for the documentation - this topic regards the Pan and Zoom feature which was made for RadChart for Windows Phone. The responsible people are notified and this article will be excluded from RadChartingKit's documentation till its Zoom/Scroll feature is released.
Regards,
