I cannot get the zoom post-callback to work on UIAxes in app designer. The pre-callback works fine. Here is what I have which is embedded in the app startup function:
h = zoom(app.UIAxes);
h.ActionPreCallback = @myprecallback;
h.ActionPostCallback = @mypostcallback;
h.Enable = 'on';
disp('A zoom is about to occur.');
disp('A zoom has occurred.');
I followed the example in the help and it works of course, but it is not on a UIAxes.
