Zooming into a plotyy-axes works fine, but if I save the figure, reopen it
using openfig, and then zoom again, the link between the axes seems to have
gotten lost. 

Here's an example

N = 10;
f = figure;
ax = axes;
plotyy(ax, 1:N, rand(1,N), 1:N, rand(1,N));
savefig(f, 'testfig.fig', 'compact')
close(f)


and then

openfig('testfig.fig')


What helps is to relink the axes using linkaxes(). I'm plotting with qt, using
Octave 8.2.0 on Ubuntu (the bug also appears on Windows). 

Maybe https://savannah.gnu.org/bugs/?func=detailitem&item_id=54079 or
https://savannah.gnu.org/bugs/?func=detailitem&item_id=53980 are linked to
that ..?
