problem with showing image in App-designer

Hi:

I meet a problem while trying to show image in an app-designer

below are my workflow:

1. in a UIAxis, patch a squre with given coordinates
2. add a text after 'patch'
3. hold on
4. load an image and show in the same UIAxis, with 'XData' and 'YData'

what I can assure is that, the parameters that determine the coordinate in patch function, and the 'XData' & 'YData' that determine the coorrdinate in 'imshow' function, are all inside the XLim and YLim of the UIAxis.

the 'patch' and 'text' function works well, result like below:

but when I use 'imshow' to add the figure, the result becomes below:

the location of text changes.

since there is no way to add .mlapp as attachment, I appreciate any suggestions.

Bests,

Yu
