MATLAB: Legend

def legend

What does string1, string2 and s fourth mean in explanation underneath

is it saved items? or something else?

Best Answer

when you do plot something you can specify your 'something' by the legend to know which plot corresponds to which function. try following: t=0:0.1:10;

y1=2*t;

y2=4*t;

plot(t,y1,t,y2);

legend('2*t','4*t');

MATLAB: How to hold legend

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

MATLAB: How to Define Title Before Plotting

Because plot is a high level command and will clear a lot of things, unlike the line function (which is what plot is calling anyway). Using hold will work:

hax = axes;
x = linspace(0,3);
hax.Title.String = 'TITLE'; % titling before plotting (doesn't work)
hold(hax,'on')
y1 = sin(5*x);
plot(hax,x,y1)
