You can use
y filter/.expression={y==0 ? nan : y}
in the options of \addplot
.
\documentclass{article}
% ---------------------------------- tikz
\usepackage{pgfplots} % to print charts
\pgfplotsset{compat=1.12}
\begin{document}
\begin{figure}
\centering
\begin{tikzpicture}
\begin{axis} [
% general
ybar,
scale only axis,
height=0.5\textwidth,
width=1.2\textwidth,
ylabel={\# Dots},
nodes near coords,
xlabel={Variation},
xticklabel style={

anchor=east,
},
%enlarge x limits={abs value={3}},
]
\addplot+[y filter/.expression={y==0 ? nan : y}] table [
x=grade,
y=value,
] {
grade value
-11 0
-10 0
-9 0
-8 0
-7 0
-6 0
-5 3

};
\end{axis}
\end{tikzpicture}
\end{figure}
\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 the siunitx
package and let that format and typeset the values for you.
Anyway, here's the quickfixed version:
\documentclass[border=3pt]{standalone}

\pgfplotsset{%

colormap={blackwhite}{gray(0cm)=(1); gray(1cm)=(0.5)},

Best Answer
One possible solution is to cacluate width and height by the given coordinates inside a
let
statement. Then save the result of the calculation to a macro and use this macro when creating the inset axis. Here is a MWE:Which produces
The inset has the desired position with the lower left corner at
(-4,2)
and the upper right corner at(0,6)
. The tick labels of the inset axis have been removed to prevent awidth/height is too small...
error. The keyscale only axis
has to be provided to the inset axis, so that the axis exactly matches the desired dimensions.Comments/alternative answers are very welcome!
