I try to implement dragging data point in sfChart based on forum
Within ChartSelectionBehavior class, OnTouchMove() Event
On Android Emulator:
When try to drag point, it seems OnTouchMove() in ChartSelectionBehavior doesn't work with ScatterSeries reliably.
Most of the time it doesn't work.
In VS2019 output, it reports
W/monodroid-assembly( 5212): typemap: unable to find mapping to a managed type from Java type 'android/view/DisplayListCanvas'
W/monodroid-assembly( 5212): typemap: unable to find mapping to a managed type from Java type 'android/view/RecordingCanvas'
Changing to LineSeries, it works well with NumericalAxis (no LogarithmicAxis)
The code is working for both ScatterSeries and LineSeries, also both NumericalAxis and LogarithmicAxis.
But the performance is quite bad.
The data point moving is not smooth compared to working Android LineSeries NumericalAxis. Can this be fixed?
Didn't test on iOS yet
See the problem at SampleChart.cs : line 30, 45, 130
