[Octave-bug-tracker] [bug #52641] Changing legend "displayname" property to empty string "" leads to printing an error

[Dan Sebald]

Follow-up Comment #2, bug #52641 (project octave):

Rik, you are saying that 

http://hg.savannah.gnu.org/hgweb/octave/file/a7dfb685d261/scripts/plot/appearance/legend.m#l415

is inefficient because it recursively calls the routine it exists in?

I'm attaching a simple mod for you to consider that gets rid of the true/false
input to updateline and replaces it with a new updatename listener.  That
seems more efficient, as keeping callback simple is typically good practice.

Also, this modification (after the patch you created and after the attached
patch is applied) works for me in gnuplot, but it doesn't work in the FLTK/Qt
toolkits.  I've verified that the callback is occurring, so I don't know what
the issue is.  For Qt/FLTK the legend text remains at "Legend String".
