I am plotting collected data against a function of the theoretical values, and calculated the correlation coefficient for the data sets. When I display it on my plot, it shows in 2 lines instead of 1.
This is what I am currently doing:
text(260,40,{'r =' r}) %where r is the correlation coefficient calculated prior in my code.
Here is how it is plotting:
Thanks in advance!

Ran in:
r = pi; % arbitrary value for testing
{'r =' r} % Matlab will put each element of a cell array on a different line in text, title, etc.
ans = 1×2 cell array
{'r ='} {[3.1416]}
figure
grid on
xlim([0 400]) % specify axis limits so the text will show up
ylim([0 80])
cv = sprintf('r = %f', r)
cv = 'r = 3.141593'
text(260, 40, cv) % use a single char vector instead of a cell array
figure
grid on
xlim([0 400]) % specify axis limits so the text will show up
ylim([0 80])
str = "r = " + r % or you can use a string
str = "r = 3.1416"
text(260, 40, str)
