Thanks, Ansley,
But my question is still unsolved.
What I want is to overlay a sketch map on the vector
fields which clearly sigh the flows and eddies. Such map may include curves
drawn manually by giving the positions of some points in the pathway of
flows with one or more arrows for direction.
I have learned that "go arrow_user.jnl" may help to draw an
arrow. Connecting it with curve by "plot/vs..." may realize my idea, but it
really needs some technique to connect them smoothly. So I am asking if there
is any other way.
Or if you could tell me how to smooth the curve by
"plot/vs...", the method above may also work.
Got it this time? Thank you very much. :)
Regards,
Jian
