  Seems fine on Octave, version 4.2.2 running on a Mac.
  Is the linkages() call part of the test? It didn’t;t seem to do anything.

linkaxes(ha, 'x') is the crucial part of the test, which fails for me in 4.3.91 
(flatpak).

It apparently does nothing because the x axis is already the same for all 
panels but what it does is to link them together, so a change in one panel 
changes all panels to be in sync.

To see that you can compare what xlim([2,9]) does if you add it before vs. 
after linkaxes(ha, 'x')

You should see that if you apply it before, the x axis is only changed for the 
active panel. In contrast if you add it after, all panels should change to [2,9]
