Look at this Example
t=0:0.1:10;
y1=sin(t);
y2=cos(t);
% ------Plot the first data----------
plot(t,y1);
h=legend('word1')
%-------Plot the second data---------
hold on
plot(t,y2);
str=get(h,'string')% get the previous legend
new_leg='word2'  % your new legend
h=legend([str new_leg])  % concatenate the new and the previous legend
