Follow-up Comment #13, bug #48427 (project octave):

I started trying to make the legend layout better match what Qt is doing. 
gnuplot currently isn't the friendliest as to key layout.  Sizes are often
specified as "characters", which of course changes with the font size.

But to my way of thinking, if the axes were set according to the gca's
position, and the key position were set according to its position, then it
should be a pretty close match.  gnuplot would just use whatever space is left
for a sample.  I think the user could at least tweak things from there even
though it might not match qt toolkit's layout.

I started down that path and it began to feel all too familiar.  This routine
__actual_axis_position__.m is giving slightly unexpected results.  Then I
searched my email and found it is this bug report from a while back

It would be best to work out what that __actual_axis_position__() should be
doing before trying to make the axes/legend layout correct.
