[Octave-bug-tracker] [bug #34148] Subplots with gnuplot overlap with plotyy

[Ben Abbott]

Update of bug #34148 (project octave):

                  Status:            Works For Me => In Progress            
             Assigned to:                    None => bpabbott

Follow-up Comment #16:

I found the problem. Consider a simpler case.


y = 1:10;
x = y; 
figure (1)
clf

subplot (1, 1, 1); 
axis ([0, 10, 0, 10])
ca1 = gca ();
ax1 = plotyy (x, y, x, y);
title ('title')
ylabel ('ylabel')
xlabel ('xlabel')

subplot (1, 1, 1)
axis ([0, 10, 0, 10])
ca2 = gca ();
ax2 = plotyy (x, y, x, y);
title ('title')
ylabel ('ylabel')
xlabel ('xlabel')


In each case, the current axes after calling subplot should be the same as it
was prior to subplot. Octave gets this wrong on the first call. On the other
hand, Matlab produces the same result each time. With Matlab the ylabel is
blue and on the left side since it is applied to pre-exiting axis in each
case.

If the "axis" command is not used, then the ylabel shows up on the right side
in each case.

This looks like a minor bug in plotyy.m. I'll prepare a changeset.
