Thank you for your question.
Chart for Android handles some of the common gestures to provide with its features. For example, you can have a look at the behaviors section
of our documentation, which demonstrates how to easily pan and zoom by simply adding a ChartPanAndZoomBehavior to the chart.
If you need custom detection of gestures, you can proceed as with any View in Android. Here's
the article that explains how to use the ScaleGestureDetector that can ease the work with scale and here's another one
that shows a more general approach towards the multi-touch gestures.
I hope this information helps.
Do you want to have your say when we set our development plans?
Do you want to know when a feature you care about is added or when a bug fixed?
