Dear all,
How do I display values on a plot (as shown in picture) or something similar to this for multiple subplots?
Thank you.

You can use text. For example
t = 0:.01:2*pi;
x = cos(t);
plot(t, x);
text(0.2, 0.4, {'This', 'is', 'a', 'test'}, 'EdgeColor', 'r')

Hi @Chunru,
Suppose I have the following code:
R1(i,:) = diag(corr(y1(:,i),y2(:,i)));
r1(:,i) = ['r = ' num2str(R1(i,:))];
That already converts the r value into a string. How would I use text on for this?

if you have a string array
r = ["r=0.1"; "r=0.2"];
Then you can do the following:
t = 0:.01:2*pi;
x = cos(t);
plot(t, x);
text(0.2, 0.4, r, 'EdgeColor', 'r')
