# Duplicate values when writing value near coordinate

I am using this code, taken from my question here. The problem arises when two x values have the same y value. Then the label I want to write near the coordinate overlaps with the other one. How can I resolve this issue, even specifically for this particular input?

\documentclass{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.9}
\usepackage{filecontents}
\begin{filecontents*}{mydata.dat}
x_0 f(x) label
%some comment
0.5 0.24 0
0.5 0.21 0.1
0.5 0.18 0.5
0.5 0.21 0.9
\end{filecontents*}

\begin{document}

\begin{tikzpicture}
\begin{axis}[
title = My title,
xlabel = {$x$},
ylabel = {$y$},
legend entries = {A},
every node near coord/.append style={anchor=south west},
]
\addplot [nodes near coords, mark = *, blue, point meta = explicit symbolic] %table {Measurements/A.dat};
table[meta = label] {mydata.dat};
\end{axis}
\end{tikzpicture}
\end{document}


Relevant question lies here, however, I would like the labels I write near the coordinates to be separated by a comma, leaving the rest of the plot untouched.

• I don't see them overlap. – user11232 Apr 17 '15 at 1:26
• @HarishKumar my apologies, I had wrong data posted. Edited, thanks! – gsamaras Apr 17 '15 at 1:36

You have to add an extra column anchor in your data with the anchor values though.

While using north west etc use an extra pair of braces like

\begin{filecontents*}{mydata.dat}
x_0 f(x) label anchor
%some comment
0.5 0.24 0  west
0.5 0.21 0.1 {north west}
0.5 0.18 0.5 west
0.5 0.21 0.9 {south west}
\end{filecontents*}
