Let's consider this example:
labels = {'A','B','C'};
hold on
for i = [1 2 3]
h(i) = plot(rand(10,1));
end
legend([h(1),h(2),h(3)],labels);
Now, I would like to plot only the first and the second plots, i.e.
hold on
for i = [1 3]
h(i) = plot(rand(10,1));
end
legend([h(1),h(3)],labels);
Is there any automatic way to change the legend from
legend([h(1),h(2),h(3)],labels);
to
legend([h(1),h(3)],labels);
?
Basically, I just want to change the index of the plots
i = [1 3]
and get the correct labels.
