Details:

When using title() on legend objects the function complains


octave:2> plot (1:10)
octave:3> hl = legend ("abc")
hl = -40.527
octave:4> title (hl, "Legend Title")
error: Invalid call to title.  Correct usage is:

 -- title (STRING)
 -- title (STRING, PROP, VAL, ...)
 -- title (HAX, ...)
 -- H = title (...)


It is simple enough to work around the title() function in Octave by getting
the "title" property of the legend object and setting the "string" property on
it.  This does label the legend, although the look is different from that of
Matlab.

Sample code for that is


plot (1:10);
hl = legend ("abc");
ht = get (hl, "title");
set (ht, "string", "Legend Title")


The visual appearance in Octave and Matlab are attached.
