How do I show only two colors in my Legend?

I only want to label in my legend the moon and the earth, so how do I get rid of the rest of the colours? Is it possible to only show the earth (yellow) and the Moon (green) in the legend?

data2=plot(moon_data);
legend([data1,data2],'Earth','Moon');

You can use the handle returned by plot() with legend() to only show specific legends. For example

hold on;
p(1) = plot(rand(1,10));
p(2) = plot(rand(1,10));
p(3) = plot(rand(1,10));
p(4) = plot(rand(1,10));
p(5) = plot(rand(1,10));

legend(p([3 5]), {'legend3', 'legend5'});
