Details:

Gnuplot produces multiple legends, when using line handles for legend
setting.
MWE:

[~, l1, l2] = plotyy([1 2 3], [1 2 3], [1 2 3], [2 2 2]);
hold on;
l3 = plot([1 2 3], [3 2 1]);
leg(1).leg = {"l1", "l2"};
leg(2).leg = {"l3"};
[l1;l2;l3]
[leg.leg]
legend([l1;l2;l3],[leg.leg]);
legend location northwest;

This code produces single legend box with legends for three lines in QT. Same
code with Gnuplot backend produces two legend boxes with three legends. One of
the legends has other legends label displayed over it.
