Re: [ferret_users] Problem with vector plot

["William S. Kessler" <william.s.kessler@xxxxxxxx>]

Your second PPL VECTOR command (final command to actually draw the plot) needs to have the qualifier /OVER
And the /OVER qualifier on VECKEY is wrong (does that not give an error?)
Where you say you get "many labels", that is because you omitted /NOLAB.
