[Octave-bug-tracker] [bug #45554] Setting label after empty errorbar plot blocks command prompt

[Dan Sebald]

Follow-up Comment #2, bug #45554 (project octave):

Confirmed bug on linux.  Since Cntrl-C is needed three times to force close, I
would think the code isn't being hung in the M-file scripts but the core
somewhere (probably waiting on gnuplot to complete its previous commands,
which aren't valid).

Note that Qt has some peculiar behavior as well.  The

errorbar(x,x,x,'.b;test;');

command does not draw a new Qt/fltk errorbar plot, but the legend text is
updated to read "test".  Gnuplot at least clears the screen on the errorbar
command, which seems better than leaving the old plot visible.
