What's the mean of "axes(handles.axes1) " in GUI plot ?

When plotting in GUI, I see someones have the line: axes(handles.axes1); What does that line mean ? Could I skip that line ? thanks very much.

It means that the current axes should be set to axes1. Anything you do like title(), xlabel(), ylabel(), plot(), bar(), legend() or whatever, will now be applied to axes1 (unless you explicitly pass a different axes into the function which would override the default current axes).

If I have only 1 axes on my GUI, Could I don't write the line axes(handles.axes1) ? :)

Yes, most likely you could omit that function call if it's the only axis on your GUI.

I create a poup menu have 3 thing: qua trinh dang ap, qua trinh dang tich, qua trinh dang nhiet. Its tag is cycle. if I write: get(handles.cycle,'string'); It don't understand and can't get the string from popup menu. I see on the internet, they write:

contents = get(handles.cycle,'String'); 
cyclevalue = contents{get(handles.quatrinh,'Value')};

Why I have to do that to get string from popup menu ? thanks

That should work. What is the value of contents? Is it null? Or do you get an error? If so, what is the error?
