[Pgfplots-features] Bug in pos argument to node?

[Florian L. <mai...@xg...>]

Hey,

I just recently discovered you can use addplot followed by a node[pos=0.3] for labeling plots. I have a tex file:

\documentclass{scrartcl}

\usepackage{tikz}
\usepackage{pgfplots}
\pgfplotsset{compat=1.16, table/col sep=comma}

\begin{document}

\begin{tikzpicture}[
  label/.style={font=\small}]]
  \begin{axis}[
    grid=major, xmode=log, ymode=log,
    x dir=reverse,
    every axis plot post/.append style={x=h, mark=none}]

    \addplot+ table[y=InfError] {h_convergence_NoneConsistent_MultiQuadrics_highfreq_14.csv} node[label, yshift=0.5cm, pos=0.3] {MQ 14};
    \addplot+ table[y=InfError] {h_convergence_NoneConsistent_MultiQuadrics_highfreq_4.csv} node[label, yshift=-1cm, pos=0.3] {MQ 4};    
    \addplot+ table[y=InfError] {h_convergence_NoneConsistent_ThinPlateSplines_highfreq_0.csv} node[label, pos=0.3] {TPS};
    \addplot+ table[y=InfError] {h_convergence_NoneConsistent_VolumeSplines_highfreq_0.csv} node[label, pos=0.3] {VS};

  \end{axis}
\end{tikzpicture}

\end{document}


The x column h is the same at all csv files, so I expect the nodes to be placed at the same x-position. But the attached PDF shows that the two MQ nodes are placed behind the VS/TPS nodes.

It also happens without logarithmic axes.

I have attached all data to reproduce the problem. Is that a bug in how pos is implemented or a misunderstanding on my side?

Best Thanks,
Florian
