Correlation between two vectors

How to show the correlation between two vectors? I know I can use the function 'xcorr', but is there a function that shows graphically this correlation?

[Adam Danz]

Directly from matlab documentation,

n = 0:15; 
x = 0.84.^n;
y = circshift(x,5);
[c,lags] = xcorr(x,y);
stem(lags,c)
xlabel('lag')
ylabel('r')

or more simply,

plot(lags, c, '-o') 

This shows a maximum correlation at lag -5 which makes sense since we circularly shifted the data by 5 units.
