Thanks for writing back.
The Windows Phone 8 ScrollViewer
behaves slightly different compared to the Windows Phone 7 one. In Windows Phone 8 Microsoft introduced the so-called Manipulation
thread which handles the user input. This aims to offload the UI thread for the rest of the processing thus implementing a really smooth scrolling experience. What happens on Windows PHone 8 by default is that the MainpulationDelta
events are directly absorbed by the ScrollViewer
without reaching the chart. We cannot prevent this from happening but what you can do is turn off this manipulation thread and use the old, Windows PHone 7 approach. For that purpose you will have to set the ManipulationMode
on the ScrollViewer
This should resolve the glitches.
