MATLAB: How to pass options from popupmenu to another callback function

You don't need to pass the selected option when the selection is made in the popup. The easiest is simply read out the popup value when you run the callback of the button.

the callback of the button should look like this:

choise = get(handles.popupmenuband,'Value'); %get selected band
switch choise
     case 1
       % plot alpha
     case 2
       %plot beta
     case 3 
       %plot gamma
      %(etcetera)
  end
