Hello,

I can plot neat pseduocolor picture.

my question is how to plot the vector, it is four column data for 2d problem, x, y, u, v. I would use the arrow to represent the v/u, but dont konw how to do it. I tried the vector->operators->surface normal->points->mesh, then I got the information box poped up says "An invalid variable (points) was specified."

Any idea  to plot 2d arrow for v/u?

Thank You!!!

I didn't find the right solution from the Internet.
