Follow-up Comment #5, bug #46325 (project octave):
Re-posting comments which are present in e-mail, but not in Savannah's bug
tracker.
Sorry, I don't know why the description didn't save. Here it is:
I used the command
gh = tf([1],[1 6 12 8]);
rlocus(gh)
The root locus which is supposed to go off to infinity does not go off to
infinity and is terminated. This seems to be the problem with all plots going
off to infinity.
Upon clicking the autoscale button, the plot vanishes, only the dotted line
representing asymptotes remain.
If I use
gh1 = tf([1],[1 6]);
rlocus(gh1)
and click autofocus, the entire plot disappears only the legend remains.
Also the coloured dots used to mark the poles and zeros are not visible. Can
anything be done to solve that?
I get it that higher roots are difficult to handle. But if the graph itself
disappears on clicking the Autoscale button, that is a rendering bug right?
Attaching screenshots, if that helps.
