Dear All,

I'm plotting the zonal wind (from a netcdf file) as contours and I would
like to display only the contour lines that are equal to "ZERO".

I tried this but it doesnt work:

'set z 3'
'set t 42'
'set gxout contour'
'd uwnd'

I also tried using CDO but the output are all missing values.

cdo eqc,0 ifile.nc ofile.nc

Can anyone suggest how can I do this in grads?

Ill appreciate any help.
