[Octave-bug-tracker] [bug #29569] the bottom right figure of second plotyy demo incorrect

[Ben Abbott]

Follow-up Comment #9, bug #29569 (project octave):

I've installed gnuplot 4.2.6 and see the same result as you. I looked that
the plot stream, but don't see anything unusual.

What is unusual is that the three examples below give very different
results.

figure(1)
clf
x = 0:0.1:2*pi; 
y1 = sin (x);
y2 = cos (x);
ax = plotyy (x, y1, x, y2);
xlabel ("X");
ylabel (ax(1), "Axis 1");
ylabel (ax(2), "Axis 2");
axis (ax(2), "square")

figure(2)
clf
x = 0:0.1:2*pi; 
y1 = sin (x);
y2 = exp(x - 1);
ax = plotyy (x, y1, x, y2)
xlabel ("X");
ylabel (ax(1), "Axis 1");
ylabel (ax(2), "Axis 2");
axis (ax(2), "square")

figure(3)
clf
x = 0:0.1:2*pi; 
y1 = sin (x);
y2 = (x - 1);
ax = plotyy (x, y1, x, y2)
xlabel ("X");
ylabel (ax(1), "Axis 1");
ylabel (ax(2), "Axis 2");
axis (ax(2), "square")

I have some errands to run. Later I'll try to create some simple gnuplot
commands to determine if the problem is with gnuplot or octave.
