[gradsusr] Displaying Data

[Jennifer Adams]

Your descriptor needs ‘dtype netcdf’ and a different variable declaration — the “99” needs a list of comma-delimited coordinate axes, perhaps like “z,y,x” but it will depend on the shape of the variables you’re describing. Please see http://iges.org/grads/gadoc/SDFdescriptorfile.html.
