Answer 1

The simplest way is:

hold all;
p1=plot(1:10,1:10);  
legend(p1,'1');  % in this way plot(x,y) is saved as variable p1 with name '1'   
p2=plot(1:10,11:20); % different data set

legend(p2,'2');  
legend(gca,'off');    
legend('show');

This is connection of few methods, it's very simple and it could be use everywhere.
