->**Note**: Directional zooming works only when [`enablePinching`](https://pub.dev/documentation/syncfusion_flutter_charts/latest/charts/ZoomPanBehavior/enablePinching.html) is true and [`zoomMode`](https://pub.dev/documentation/syncfusion_flutter_charts/latest/charts/ZoomPanBehavior/zoomMode.html) is [`ZoomMode.xy`](https://pub.dev/documentation/syncfusion_flutter_charts/latest/charts/ZoomMode.html#xy), as it relies on the pinch gesture direction to determine the zoom axis.
+>**Note**: 
+* Directional zooming functions when both [`enableDirectionalZooming`]() and [`enablePinching`](https://pub.dev/documentation/syncfusion_flutter_charts/latest/charts/ZoomPanBehavior/enablePinching.html) are set to `true`, and [`zoomMode`](https://pub.dev/documentation/syncfusion_flutter_charts/latest/charts/ZoomPanBehavior/zoomMode.html) is set to [`ZoomMode.xy`](https://pub.dev/documentation/syncfusion_flutter_charts/latest/charts/ZoomMode.html#xy).
+* This feature is intended for touch gestures and is ineffective with a mouse or trackpad.
