I happened to find in the IDL \examples\visual directory the file
show_stream.pro.

Running these shows some of its features:

IDL> Show_Stream         ; uses ribbons

IDL> Show_Stream, /Lines

IDL> Show_Stream, /Tubes

IDL> Show_Stream, /Vector

It sounds like the last option is the one that would interest you, and it
relies on vector_field.pro in the IDL \lib directory.

Hope this is of some help.

Cheers,
