Plotting 3D vectorfield

[JJonasson]

Hello

I would like to plot a windfield with arrows in 3D from octave, that is I would like to be able to use the gnuplot "arrow" command from within octave. This should be possible, shouldn't it, but how?

What I am looking for is some sort of 3D quiver function, if you know what I mean.

I use Octave 3.0 and gnuplot 4.2

Thank you

/Jonas

If you have data on triangular meshes you could try the FPL package:

Or just use quiver3
