ZoomPanBehavior class

Customizes the zooming options.

Customize the various zooming actions such as doubletapZooming, selectionZooming, zoomPinch. In selection you can long press and drag to select a range on the chart to be zoomed in and also zooming you can customize the selection rectangle using Borderwidth,color and RectColor.

zoomPinching can be performed by moving two fingers over the chartDefault mode is ZoomMode.xy. Zooming will be stopped after reaching maximumZoomLevel.

Note: This is only applicable for SfCartesianChart.
