How can I fix legend in an animate plot 2D?

figure(1)
for j = 1:length(t)
    plot(x,u(:,j),x,v(j,:),x,LF(j,:))
    pause(0.1)
end

I would see the legend also the animate is running. Not only at the end of this. Thanks all.

clc; clear all ;
x = linspace(-2*pi,2*pi);
y1 = sin(x);
y2 = cos(x);

for i = 1:100
    plot(x,rand(1)*y1,'r',x,rand(1)*y2,'b')
    legend('sin(x)','cos(x)')
    pause(0.1)
    drawnow
end

Not specific to your query but related to it... if some reader wants to animate the legend with every data point, then following code works with a little modification to @KSSV code. (...can be repeated for multiple vectors & likewise legends):

x = linspace(-2*pi,2*pi);
y1 = sin(x);
for i = 1:20
    plot(x,rand(1)*y1,'r');
    legend("sin(" + num2str(x(i))+")");
    pause(0.1);
    drawnow;
end
