Your error likely occurs because this command: axes(handles.axes1) refers to an element of GUI 1 whereas the line is executed in GUI 2 and the latter does not recognize the variables coming from GUI 1 because they have their own workspace.

You can use the addNewPositionCallback method to add your own callback function to be executed whenever the rectangle changes its position.

You can group the axes that share the same properties (i.e. are visible or not at the same time) into 1 variable (eg. TopAxes and BottomAxes) and thus update their properties at the same time in the Listbox callback. Here is an example with 6 axes, 3 at the top...
