How to zoom charts using fingers?

[tanthinh1510]

You could try a PinchArea on top of the chart view and calling the chart view's zoom function appropriately from the pinch area's signal handlers.

Thanks anda_skoa! I used PinchArea and it zoom ok.
And I want to move charts using one finger touch screen and drag as video below (from 2.01 - 2.03)
