Print value of correlation to a plot displaying two functions

Hi everyone,

I have a plot displaying observed (y1) and simulated (y2) data vs year (x). I want to plot each one as a time series to visually compare them, but I would also like to print the value of the rank correlation between them :

corr(y1,y2,'Type','Kendall')

Basically I want to print the result of this on the plot, without having to copy-paste the value

figure(); hold on;
plot(Year,y1);
hold on;
plot(Year,y1);
txt = {'Corr = *value of correlation*'};
text(4,0.5,txt)

Any ideas ?

Thanks !

R = corr(y1,y2,'Type','Kendall') ; 

figure(); hold on;
plot(Year,y1);
hold on;
plot(Year,y1);

str = sprintf('%f',R) ; 
txt = ['Corr = ',str];
text(4,0.5,txt)

It works great, thanks !

Perhaps like this?

v = corr(y1,y2,'Type','Kendall');
txt = ['Corr = ', num2str(v)];
text(4, 0.5, txt)

Thank you ! It works as well :)
