I didn't modify anything.  See the following

--------------------------------------------------

octave:1> figure
octave:2> axes
octave:3> get (gcf, 'position')
ans =

   304   215   560   380

--------------------------------------------------

So the Y size of the figure really is 380 for me.

The size does not change perceptibly and the size goes back to its original value.

--------------------------------------------------
octave:5>  set (gcf (), "position", pos+1)
octave:6>  set (gcf (), "position", pos)  
octave:7> pos = get (gcf (), "position")
pos =

    25   345   560   380
--------------------------------------------------

Is the original Y-size controlled by the window manager?  Could it be that we have different screen sizes which is causing the difference?
