Is there a possibility with pgfplots to print numbers with no decimals for the nodes? By this, I mean printing '2' instead of '2.0e0'.

In my case, I want to remove the decimal part and add the percent sign, which would give'2%' instead of '2.0e0'.

Furthermore, how can I put the text node '1%' on the top of the corresponding bar ? (if the bar is negative, it won't be anymore on the top)

Here is a sample code and a picture which I want to improve. enter image description here

\documentclass{standalone} \usepackage{filecontents,pgfplots,pgfplotstable} \begin{filecontents}{data.dat} id a b name 0 1.1 20 Name1 1 2.2 -10 Name2 2 3.3 15 Name3 \end{filecontents} \begin{document} \pgfplotstableread{data.dat}{\donnees} \begin{tikzpicture} \begin{axis}[ybar,xtick={0,1,2},xticklabels={a,b,c},point meta=explicit symbolic,nodes near coords=$\pgfplotspointmeta\%$] \addplot table [x={id}, y={b},,meta expr=\thisrow{id}] {\donnees}; \end{axis} \end{tikzpicture} \end{document}

You can use nodes near coords={\pgfmathprintnumber[fixed, precision=0]{\pgfplotspointmeta}\%} to format the numbers using PGF's very flexible number formatting macro. Note that you have to use point meta=explicit instead of point meta=explicit symbolic if your meta data is numeric, otherwise the number parser will fail.

\documentclass[border=5mm]{standalone} \usepackage{filecontents,pgfplots,pgfplotstable} \begin{filecontents}{data.dat} id a b name 0 1.1 20 Name1 1 2.2 10 Name2 2 3.3 15 Name3 \end{filecontents} \begin{document} \pgfplotstableread{data.dat}{\donnees} \begin{tikzpicture} \begin{axis}[ ybar, xtick={0,1,2}, xticklabels={a,b,c}, point meta=explicit, nodes near coords={\pgfmathprintnumber[fixed, precision=0]{\pgfplotspointmeta}\%} ] \addplot table [x={id}, y={b},meta expr=\thisrow{id}] {\donnees}; \end{axis} \end{tikzpicture} \end{document}

  • I get '0%' for each bar, is there an error in the code ? Commented Sep 6, 2013 at 20:38
  • @user81566: I get the result shown in the screenshot when I compile my code. What version of PGFPlots are you using? Commented Sep 6, 2013 at 20:46
  • I have the version 1.7, which should be the latest version according to Miktex. Am I right ? Commented Sep 6, 2013 at 20:58
  • @user81566: The current version is 1.8, but I wouldn't have thought that there was a change between 1.7 and 1.8 that would affect this. When you copy my code into a new document, you get 0%? Or only when you try to adapt this for your own code? Commented Sep 6, 2013 at 21:09

    Yes but I get 0,1,2 percent somehow. Not 500,1000 as you have. Oops picture is changed nevermind :) Commented Sep 8, 2013 at 12:43
