# TIKZ drawing vector field from external file

I would like to draw a vector field from a data file. I tried to adapt code from Manual for Package pgfplots but this doesn't work

\documentclass{standalone}
\usepackage{pgfplots}

\begin{document}
\begin{tikzpicture}
\begin{axis}[title=Quiver and plot table]
\end{axis}
\end{tikzpicture}
\end{document}


where data file vector_field.dat is :

x y u v
0 0 1 0
1 1 1 1
2 4 1 4
3 9 1 6
4 16 1 8


During compilation I get for example this error:

! Undefined control sequence.
\pgfk@/data point/quiver/u ->\thisrow
{u}
The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., \hobx'), type I' and the correct
spelling (e.g., I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.
! Package PGF Math Error: Unknown function u' (in '{u}').


Does anyone now how to solve it? I would be grateful for any help.

I get the error message ! Package PGF Math Error: Unknown function thisrow_unavailable_load_table_directly'. If I do that, that is, if I use \addplot ... table {vector_field.csv};, the document compiles:

\documentclass{article}
\usepackage{pgfplots}

\begin{filecontents}{vector_field.dat}
x y u v
0 0 1 0
1 1 1 1
2 4 1 4
3 9 1 6
4 16 1 8
\end{filecontents}


I'm not sure if I read this answer correctly, but I paste the MWE as is, (pgfplots 1.5.1), and I still get "! Package PGF Math Error: Unknown function 'thisrow_unavailable_load_table_directly'`". – sdaau Jul 6 '14 at 6:13
