Hi all,
this question has been asked many times, but nobody has ever provided an
answer yet.

How can I create a correlation maps in Grads?
I have two monthly time series of soil moisture (120 months), and I
would like to have a point-to-point correlation between them. Basically,
i need to correlate the time series of each grid point in dataset no.1
with the time series of the corresponding grid point in dataset no.2. In
this way, I would obtain a map of correlations.

Any help would be very much appreciated.

Ciao,
Stefano
