How to display labels on points of a tikz plot
I plot a scatter plot using pgfplots and automatically label every single mark with its description. When two marks are too close together, the descriptions overlap. Can I change the alignment of one or more chosen nodes? In the example, I'd like to change node c to e.g. north east.
\begin{filecontents}{test.dat}
x y desc
1 1 a
1 1.2 b
1 1.195 c
\end{filecontents}
\documentclass{article}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}
\begin{axis}[nodes near coords,point meta=explicit symbolic,nodes near coords align={anchor=south west},]
\addplot[scatter,only marks,] table[x=x,y=y,meta=desc] {test.dat};
\end{axis}
\end{tikzpicture}
\end{document}
