I'm trying to draw a matrix plot with the shown values in percentage.
I already tried:
nodes near coords = {\pgfmathprintnumber\pgfplotspointmeta\%}
Unfortunately this didn't work out.
Here is my code:
\documentclass[border=3pt]{standalone} \usepackage{pgfplots} \pgfplotsset{width=5cm, height=18cm, compat=1.13, colormap={blackwhite}{gray(0cm)=(1); gray(1cm)=(0.5)}, xticklabels={LPIBG, ALL, HPIBG }, xtick={0,...,2}, ytick=\empty }\begin{document} \begin{tikzpicture} \begin{axis}[enlargelimits=false, nodes near coords = {\pgfmathprintnumber\pgfplotspointmeta\%}, xlabel style={font=\footnotesize}, ylabel style={font=\footnotesize}, legend style={font=\footnotesize}, xticklabel style={font=\footnotesize}, yticklabel style={font=\footnotesize}, colorbar, colorbar style={ ytick={0,20,40,60,80,100}, yticklabels={0,20,40,60,80,100}, yticklabel={\pgfmathprintnumber\tick\%}, yticklabel style={font=\footnotesize}}, point meta min=0, point meta max=100, every node near coord/.append style={xshift=0pt,yshift=-7pt, black, font=\footnotesize}, ]
\addplot[ matrix plot, nodes near coords, mesh/cols=3, point meta=explicit] table[meta=C]{ x y C 0 0 80 1 0 36 2 0 40 0 1 64 1 1 80 2 1 60 0 2 52 1 2 84 2 2 72 0 3 72 1 3 28 2 3 32 0 4 56 1 4 84 2 4 80 0 5 72 1 5 52 2 5 44 0 6 4 1 6 84 2 6 41 0 7 37 1 7 69 2 7 84 0 8 63 1 8 53 2 8 82 0 9 78 1 9 74 2 9 39 0 10 39 1 10 63 2 10 88 0 11 76 1 11 74 2 11 49 0 12 39 1 12 6 2 12 88 0 13 46 1 13 33 2 13 75 0 14 88 1 14 67 2 14 54 0 15 79 1 15 83 2 15 75 0 16 50 1 16 46 2 16 71 0 17 92 1 17 71 2 17 75 0 18 46 1 18 33 2 18 8 }; \end{axis} \end{tikzpicture} \end{document}

It does not work in your MWE because you are overwriting it by also giving the option
nodes near coors
to the\addplot
command. Remove the latter one (or specify format here), and it will print. I added a thinspace before the percentage sign, although it can also be recommended to load thesiunitx
package and let that format and typeset the values for you.Anyway, here's the quickfixed version:
