Re: rlocus not working in fltk

Lukas, I did some more tests and found that only 3) works with subplots!

So for now I would suggest using 3) in rtlocus.

1)
figure ("visible", "off");
...
set (gcf, "visible", "on");

2)
axes
set(gcf,""visible", "off");
...
set (gcf, "visible", "on");

3)
hplt = plot (args{:});
set (gcf,"visible","off");
...
set (gcf, "visible", "on");

I confirm this problem on OS X 10.8.5 and Octave 3.6.4. You may want to file a bug report.

Thanks Lukas, I submitted a bug report.
