Hi,

How can I get both zoom and pan to work on iOS or Android?

Thanks

I have been unable to get gestures to work correctly with maps. Do you have an example. Why can't your internal methods work. Panning works fine, and zooming works fine if only one of them is enabled but if both are enabled only the zoom works on mobile devices.

Zoom works alone by drawing a rectangle, isn't it?
If you want to zoom by a pinch gesture, you'll need to implement gestures manually like in that application I suggested in the last post.
I'll try to do the same with a Map series to see if there's any problem with that.

Couple of questions on this.

How can pannining past beginning end of axis be prevented?

How can zoom be prevented going too far in or out?

How can the aspect ratio be mainained when zooming?

Thanks.

Hello,

You have to add extra logic to do all this at handlePan and handleZoom methods.

I more or less have this working as I want, except zooming lags on Android devices. Do you have any recommendations?
