I currently have an issue aligning ticklabels when using a comma as decimal separator.
For x ticklabels the alignment works fine and no modification is required. However, for y ticklabels, I can't figure the right way to overcome the alignment problem. I tried nodes={depth=somelength} as in Pgfplots: legend depth but it does not seem to work, seemingly due to the rotate=90 option.
Here is a MWE.
\documentclass[tikz]{standalone}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}
\begin{axis}[%
width=7cm,
height=4cm,
/pgf/number format/use comma,
yticklabel style={nodes={text depth=100pt,anchor=north},rotate=90},
xticklabel style={nodes={text depth=100pt,anchor=north},rotate=0},
]
\addplot+[domain=0:1,samples=10] {x};
\addplot+[domain=0:1,samples=10] {x^2};
\end{axis}
\end{tikzpicture}%
\end{document}
