Chart touch operations remap

[adenisyuk]

Highcharts Android v7.0.3

Is it possible to change the touch gestures for chart operations to following? :

1. panning is made with one finger gesture
2. zooming is made by pinch to zoom two finger gesture
3. tooltip: -- appears when user long presses on the chart area -- follows the finger while the gesture is not interrupted (MotionEvent.ACTION_MOVE) -- disappears when touch gesture is finished (MotionEvent.ACTION_UP)

Hi @adenisyuk ! Thanks for your question. When it comes to 1 and 2, there was a question about that already (link). As for the tooltip, things are more complicated. There is a WebView embedded inside the HIChartView which contains the original JS chart. Every touch event which you can set to HIChartView doesn't apply directly to specific chart behaviours. Anyways, these matters are still in discussion and we are working hard to make the Highcharts wrapper feels more like normal Android view.

Additionally, to make tooltip following the finger, you can use setFollowTouchMove() method.
