I would like to sync two ChartTrackBallBehavior across two charts. The exact same issue is discussed for WPF here: http://www.telerik.com/forums/sync-trackball-move-on-two-charts and there is also a WPF sample here: https://github.com/telerik/xaml-sdk/tree/master/ChartView/WPF/TrackBallSyncedCharts.
Now unfortunately the ChartTrackBallBehavior on UWP does not have a Position property, so I cannot implement that solution. Is there a way to achieve the same in UWP? Or is it planned to implement the Position property in a later version also for the UWP ChartTrackBallBehavior?
