Follow-up Comment #10, bug #43895 (project octave):

You didn't paste the results of getting the x and y data from the plot, but
someone on the list already provided that. Including here for completeness in
case this gets forgotten:

>> get(h,'xdata')

ans =

         0    0.2000    0.4000    0.6000    0.8000    1.0000 1.2000    1.4000
  1.6000    1.8000    2.0000

>> get(h,'ydata')

ans =

   -2.2789    0.3236   14.0514   -0.6138   -5.8441   -7.2346   -5.8441
-0.6138   14.0514    0.3236       Inf

So this is one more point than what is returned, and one more point than what
Octave currently plots. So I think we all agree that the return value is
correctly 10 points, but the plot should extend to the pi or 2*pi value.
