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

Sir,

But it is not holding the Marker of those legends. What to do to hold the marker in legend?

Thank you.

Hello,

To update the Legend box try this code. The code@Azzi Abdelmalek has written is 80% correct just you need to update few lines (see below)

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

%------These lines you should update--------%

str(end) = [] % delete last element of the cell arrray.

str{end+1} = "word2"; % Adding string

h = legend([str]); % Updating legend box
