Update of bug #49494 (project octave):

                 Release:                   4.2.0 => 4.2.1

Follow-up Comment #5:

I am not sure why inserting "drawnow" helped in that specific RC. It no longer
changes anything for me, too. Sorry that I gave wrong information. I was under
the impression that "drawnow" would trigger an update of all graphics
properties.

I also tried in Windows and got the same result as the OP.

The example in comment #0 works if either "ytick" or "ytickmode" is set
*before* the last call of "plot". So maybe both should update the axis limits
when changed. I can provide a changeset if this is the case.
Do we really want that the axes limits change in that case? Or is that the
bug?

I had to slightly modify your script so that it could run in Matlab:

>> figure;
plot([0 1],[-2.02 1.3311],'k','linewidth',2);
yl = get (gca, 'ylim')
set(gca,'ytickmode','manual')
yl = get (gca, 'ylim')
text(.1,.5,num2str(yl(1),'%3.1f'))
yl = get (gca, 'ylim')

yl =

   -2.5000    1.5000


yl =

   -2.5000    1.5000


yl =

   -2.5000    1.5000


I get the same results when I execute the script line by line.
