Can't get the legend right

Hi
I plotted a few things on the chromaticity diagram below.
h1 to h3 are to plot three black lines, h4 is to plot dataset A, and h5 is to plot dataset B (with psudo code given below).
h1 = plot(line1)
h2 = plot(line2)
h3 = plot(line3)
h4 = plot(dataset A)
h5 = plot(dataset B)
When I put
legend
It shows the legend as below.
But I only need the legend for datasets A and B.
How to use the legend properly in this case?

One way is to pass the graphics objects (i.e., lines, etc.) in as inputs to legend:
figure()
h1 = plot(1:10);
hold on
h2 = plot(2:11);
h3 = plot(3:12);
% legend for h2 and h3 only
legend([h2 h3],{'h2' 'h3'})
Another way would be to set the HandleVisibility of the objects you don't want in the lengend to 'off':
figure()
h1 = plot(1:10,'HandleVisibility','off');
hold on
h2 = plot(2:11);
h3 = plot(3:12);
% no need to supply [h2 h3] as the first argument this time
% (probably still a good idea though)
legend({'h2' 'h3'})
