ZoomPanBehavior class
Customizes the zooming options.
Customize the various zooming actions such as tap zooming, selection zooming,
zoom pinch. In selection zooming, you can long-press and drag to select a
range on the chart to be zoomed in and also you can customize the selection
zooming rectangle using selectionRectBorderWidth
,
selectionRectBorderColor
and selectionRectColor
properties.
Pinch zooming can be performed by moving two fingers over the chart.
Default mode is ZoomMode.xy. Zooming will be stopped after reaching
maximumZoomLevel
.
Note: This is only applicable for SfCartesianChart
.
