[ferret_users] Just pick up a particular month from monthly data...

[Seon Tae <stkim@xxxxxxxxxxx>]

Hi all

I have 100 year-monthly SST anomaly data averaged in NINO 3 region. I want 
to plot time series after picking up SST value of a particular month of each 
year.
I mean, for example, I want to obtain time series plot for January for 100 
years.
I tried to find it in the Q and A archive on the website but i couldn't
Could you please help me?

Thank very much in advance.....
