Loop over subplots - matlab

Question

Somehow, the title, xlabel, ylabel, ylim and xlim does not stay fixed in the script below, how do I fix this?
x = 0:0.01:1;
figure
p1 = subplot(2,1,1);
xlabel(p1, '$x$','Interpreter','LaTex', 'Fontsize', 16);
ylabel(p1, '$\sin(x+t)$','Interpreter','LaTex', 'Fontsize', 16);
title(p1, 'Sine','Interpreter','LaTex', 'Fontsize', 20);
ylim(p1, [-1 2])
xlim(p1, [0 1])
p2 = subplot(2,1,2);
xlabel(p2, '$x$','Interpreter','LaTex', 'Fontsize', 16);
ylabel(p2, '$\cos(x+t)$','Interpreter','LaTex', 'Fontsize', 16);
title(p2, 'Cosine','Interpreter','LaTex', 'Fontsize', 20);
ylim(p2, [-2 1])
xlim(p2, [0 1])
for t = 0:0.1:2
plot(p1, x, sin(x+t))
plot(p2, x, cos(x+t))
pause(0.1)
end

Answer 1

By default, since you haven't got hold on or hold all, when you replot in the loop everything is reset. Since you only want to change one set of values in each graph, you can use set rather than plot here to get around the issue.
First, after each subplot is called, plot the initial graph and take a handle for it:
p1 = subplot(2,1,1);
h1 = plot(p1,x,sin(x);
Then continue on setting up the labels, etc, as you already do.
In the loop, to replace the data in your existing graph:
for t = 0.1:0.1:2
set(h1,'Ydata',sin(x+t))
set(h2,'Ydata',cos(x+t))
pause(0.1)
end
