Re: plot on a large region

[Jaison Kurian <jaison@xxxxxxxxxxxxxxxxxx>]

Hi Tony,
           It can be done easily with the qualifiers "/VLIMITS" & 
"/HLIMITS" with the FILL command as shown below :

   set data levitus_climatology
   let sst = temp[k=1,x=-98:10,y=10:65] ! extract data for smaller
                                        !    region
   fill/lev=(0,30,0.25) sst  ; pause    ! the default way
                                        ! now use "/vlim & /hlim"
                                        !  to specify the larger reg. 
   fill/vlim=10:85:5/hlim=-100:30:10/lev=(0,30,0.25) sst

Hope This Helps

With Regards 

Jaison
