Axis position is shifted when YtickLabel gets different number of digits in App designer.

I made an axis to plot a spectrum on App designer. When data of spectrum was changed and the YtickLabel gets different number of digits, the position of the Y axis was shifted as shown in the attached figure. Is there any way to prevent the shift without turning off auto y axis range, and without normalization of the spectrum data?

After reading Bjorn Gustavsson's comment, I got a hint from his comment and found a good way to solve the problem.

I just put

app.axis.InnerPosition = [46.4000 53.4000 436.1000 156.6000];

after I did "plot".

Thank you for the advice from Bjorn Gustavsson!!

The cumbersome way of explicitly aligning the the position of the axes after each plotting might work? Something like this perhaps:

indefinite = 123; % just for illustratino
for i1 = 1:indefinite
  x = randn(321,1);
  y = rand(321,1);
  t = 0:321;
  sph1 = subplot(2,1,1); % more modern means exist
  plot(t,y)
  sph2 = subplot(2,1,2);
  plot(t,x)
  pos1 = get(sph1,'position');
  pos2 = get(sph2,'position');
  set(pos2,'position',[pos1(1),pos2(2),pos1(3),pos2(4)])
  drawnow
end

That should force the axeses to line up in the vertical direction.

Actually, your answer didnot work on app designer.

But I got a hint from your comment and found a good way to solve the problem!!!

app.axis.InnerPosition = [46.4000 53.4000 436.1000 156.6000];

Good. I haven't worked with app designer - but there ought to be a similar handle-graphics interface to the plottings, so now you now roughly what to look for and where...
