Are the Steema Charts now available for Mono for Android? I am looking forward to it.

Actually Im porting a Java code snippet from https://market.android.com/details?id=com.steema.teechart.android. Re.: I managed to get this example working in c#/MonoDroid http://stackoverflow.com/questions/2537238/how-can-i-get-zoom-functionality- for-images which is actually this code http://www.zdnet.com/blog/burnette/how-to-use-multi-touch-in-android-2-part- 6-implementing-the-pinch-zoom-gesture/1847 (which is from a book "Hello, Android") unfortunately the licence says "Copyrights apply to this source code. You may use the source code in your own projects, however the source code may not be used to create training material, courses, books, articles, and the like." which suggests to me that I can't share my port :-( Yes, thanks, found that example too. Re.: I don't think it uses e.Size though. The class EclairMotionEvent uses @event.PointerCount if that helps. You can probably trace it through the Java version to figure out what's going on. PointerCount was the key! Using it I get pinch zoom code being reached. I think Ill need to tweak it a little bit to work properly ;-). Thank you very much!

Here is a 'panning' example that I can share https://gist.github.com/848571 in case that is of use. Maybe it can be a starting point for you. It only does panning though, not zooming; and doesn't include the two 'helper' classes WrapMotionEvent and EclairMotionEvent which i think are key to tracking the two fingers. Good luck!

StackOverflow? My question is that Im trying to implement pinch zoom in a custom control overriding OnTouchEvent. There, when e.Action == MotionEventActions.Move I check if e.Size > 1 to see if more than one fingers is moving on the screen. However Size always returns zero. AFAIK this works fine in Java for Android. Is this a bug or should I use a different argument? Thanks in advance.
