Mac zoom Support?

[KunalKshatriya]

The pan and zoom doesnt work for Mac, I fixed zoom by creating the PlatformTouchEffect for Mac (used the same file as that of iOS).

To make zoom work,

1. I added the following to the PlotController.cs,
   #if MACCATALYST
   this.BindMouseWheel(OxyPlot.PlotCommands.ZoomWheel);
   this.BindMouseWheel(OxyModifierKeys.Control, OxyPlot.PlotCommands.ZoomWheelFine);
   #endif

2. added the Pan gesture recognizer, and raised the onTouchAction

                CGPoint delta = panGestureRecognizer.TranslationInView(view);
                CGPoint point =  panGestureRecognizer.LocationInView(view);
                var touchArgs = new TouchActionEventArgs(1,
                   TouchActionType.MouseWheel,
                   new Point[] { new(point.X, point.Y) },
                   true)
                {
                    ModifierKeys = OxyModifierKeys.None
                };
                touchArgs.MouseWheelDelta = (int)((1000 + delta.Y) / 1000);
                onTouchAction(Element, touchArgs);
   

However, it didn't work. Is there something I am missing?

I don't think the iOS version of the PlatformTouchEffect will work on macOS because iPhones don't handle mouse-related events. For reference, you can take a look at the Xamarin version of the macOS PlatformTouchEffect implementation：PlatformTouchEffect ，and don't forget to add the mouse wheel event.

Thanks for the response, I will take a look at it. With the current code (which I provided in the question) does get me the mouse wheel events. However forwarding it to onTouchAction, doesnt seem to do anything.
