[gradsusr] Draw shapefile in GrADS error

[Rafanoharana Serge Claudio]

Dear all,

Did I miss some steps in drawing shapefile? I want to draw a polygon. I
followed the GrADS command to draw shp from
http://www.iges.org/grads/gadoc/gradcomddrawshp.html but always getting the
message No scaling environment.
what I did are:
'set shpopts 5'
'draw shp shp_name'


Thank you,

-- 
Serge
