Ok, in what form does the data have to be in order to VectorPlot3D to work?

try 

Partition[Partition[Seznam, 3], 3] // ListVectorPlot3D

to see if that's what you want
POSTED BY: Sandu Ursu

This works!

Thank you!
POSTED BY: Mitja Jan?i?

Hmm, one more:

And how do I plot a vector starting at any point in space? For example I want to plot (0,0,1) beginning in (1,1,1)?

Based on your other post, I think you have figured this out by now:

Graphics3D[Arrow[{{1, 1, 1}, {1, 1, 1} + {0, 0, 1}}], Axes -> True, AxesLabel -> {x, y, z}]
