I expect the result below ...

	ylim_before_ticks = [60 140]
	ylim_after_ticks = [60 140]
	ylim_after_ylim = [56 140]

OK. I get:
octave:1> plot_test2
ylim_before_ticks =

    60   140

ylim_after_ticks =

    60   140

ylim_after_ylim =

    56   140

octave:2> get(gca(),"ytickmode")
ans = manual
octave:3> get(gca(),"ylimmode")
ans = manual

=====================================
So, if this is all as you expected, the next step is to try to
explain this in the Manual.  It is a pretty common requirement
to set x and y axes so that specific points are indicated, like
this example.  So, this should be made as straightforward as
possible. A good place for an example in the Manual.

Also, the plot is correct, and exactly what I wanted.

Thanks,
Michael
