[gradsusr] Help to draw the Domain area in the plot

Dear Muhammdhn,

Can you try top create a ctl file for your netcdf file?Use the
GrADSNcPrepare function in the bin directory.
Once you have created a ctl file, use 'open' instead of 'sdfopen'.

Regarding your code, if you are going to plot an area, the command should be
set lat  lat1 lat 2
set lon lon1 lon2

If my understanding is correct, set cint is only used for contour plots and
not for shaded plots unless you want to plot contour lines over the shaded
plot.


If you want to remove the plot outside the shapefile, you can use
'masking'. See this link.http://www.ncl.ucar.edu/Applications/mask.shtml
