Random graph showing up on my GUI?

Hello. Can someone please point to me why my GUI background turns into a plot graph while trying to run accelerometer data? Here is the only button it occurs on
% --- Executes on button press in Read.
function Read_Callback(hObject, eventdata, handles)
% hObject handle to Read (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
comPort = '/dev/tty.usbmodemfa131';
[accelerometer.s,serialFlag] = setupSerial(comPort);
calCo = calibrate(accelerometer.s);
a = 0;
if a == 0
[gx gy gz] = readAcc(accelerometer,calCo);
r = sqrt((gx^2)+(gy^2)+(gz^2));
guidata(hObject, handles);

Are you sure you didn't place a gigantic axes control behind all your other controls on your GUI? And then somehow (not shown here) you plot something to it? What gets plotted? Is it anything you recognize?

I can't run it without the fig file. Upload it and the m-file somewhere and tell us where.

Hey Amed, I had the same issue with a realtime plot in which I had to open another Gui. Whenever I opened the other Gui, its background had the realtime plot on it too. I have no idea how to fix this with code, I just edited the second Gui and made a much bigger textbox that would cover up the entire frame of the Gui and it did the trick, the graph is no longer visible where it must not. You should give it a try.
