How do I get the text command to display my character string in one line on a plot?

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!

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)
