Thank you for the interesting question.
The desired functionality can be easily achieved by creating an extended Pan&Zoom behavior that will synchronize both charts Zoom and PanOffset properties:
ExtendedPanZoomBehavior : ChartPanAndZoomBehavior
.secondChart = secondChart;
// synchronize the Pan and Zoom properties of the second chart
Regarding your second question - yes, you can easily add the desired functionality by implementing a PreviewGesture event handler. More information may be found in this blog post
I hope this information is useful. Do not hesitate to write us back should you have any other question.
