I can't find an answer online, please help me. The following plot shows the percentage of 3 groups. The red line is the average (and needs to stay at 13.8).

How can I move ONLY the node "2.9" a little bit up? (here it is not really problematic, but I have other graphs where the number and the red line are overlapping - looks terrible!)....

Thank you very very much!

    Please post a true MWE... there are certainly some packages not needed for this problem. And try to avoid an empty line between each line of code. – user31729 Jul 9 '14 at 17:56

    @Jake: Ok, sorry, I was distracted ;-) I remove my previous comment – user31729 Jul 9 '14 at 18:23
  • @Kate, people will be more likely to answer if a true MWE is posted. As Christian notes, you have many packages/options that only serve to complicate the issue. Here's a potential MWE (linebreaks lost in comment, but you get the idea): \documentclass{standalone} \usepackage{pgfplots} \pgfplotsset{compat=1.10} \begin{document} \begin{tikzpicture} \begin{axis}[ybar,xtick=data]; \addplot[nodes near coords] coordinates {(1, 10) (2, 5)}; \end{axis} \end{tikzpicture} \end{document} With this MWE, you could ask a more general question: How to adjust the position of the label node on a single bar? – Paul Gessler Jul 13 '14 at 12:23

You can move a single node near coord by using a conditional yshift that checks the current coordinate index, which is stored in the macro \coordindex:

\documentclass{article}
\usepackage{pgfplots}


\begin{document}
\pgfplotsset{every axis/.append style={
    font=\footnotesize,
    line width=0.5pt,
    bar width=7pt,
    tick style={line width=0.4pt}}}

\begin{tikzpicture}
\begin{axis}[
    xlabel=Test,
    ymin=0, ymax=100,
    ylabel=percentage,
    enlargelimits=0.15,
    ybar,
    symbolic x coords={1,2,3},
    xtick=data,
    width=12cm,
    bar width=10pt];

\addplot [black, fill=black,
    nodes near coords,
    every node near coord/.append style={
        yshift={\ifnum\coordindex=1 1ex\else 0pt\fi}
    }
]
coordinates {(1, 55.6) (2,11) (3,2.9)};

\addplot[red,mark=none, sharp plot, line width=0.6pt]
coordinates {(1,13.8) (3,13.8)};

\end{axis}

\end{tikzpicture}

If I understood your question properly then your problem is that the average plot sometimes overlaps the values on top of the bars. I have came up with a solution, but you will have to omit the nodes near coords option from your bar plot, and manually add the nodes after drawing the average plot.

The solution I'm posting has different values than yours to demonstrate the two options I have included. See the two middle bars, first I have added 1.5 ex height to the node, the second I have added a faded background so the crossing red line won't be so disturbing. (Note that if you use the faded background solution you'll have to include the fadings TikZ library.)

Also I have lengthened the average plot line to extend to the edge of the bars.

This is a solution -- simply draw the the 3rd ybar independently and add node near coords key with raisebox command into the option.

Note: To avoid shift of xticks, ybar key should move to individual addplot.

nodes near coords=\raisebox{0.3cm}{\pgfmathprintnumber\pgfplotspointmeta}
