Hi!
I'm using pgfplots 1.10 and observe the following problem. The x label
shifts down a bit if I introduce extra x ticks, even if their labels are
empty. The following example produces the observed behavior:
\documentclass{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=newest}
\begin{document}
\begin{tikzpicture}
\begin{axis}[
width=4cm,
xlabel=Test,
axis x line=bottom,
axis y line=left,
]
\addplot [black] {x^2};
\end{axis}
\end{tikzpicture}
\begin{tikzpicture}
\begin{axis}[
width=4cm,
xlabel=Test,
axis x line=bottom,
axis y line=left,
extra x ticks={0},
extra x tick labels={},
]
\addplot [black] {x^2};
\end{axis}
\end{tikzpicture}
\end{document}
It does not happen with the old, static, label placement (e. g. if I
remove the compat setting). I was not able to test with 1.11, but
there's nothing related mentioned in the release notes, if I did not
overlook it. Any ideas what I'm missing or if it is a bug and how to
work around it? I need two adjacent graphs in subfloats but only one of
them has extra ticks, so the spacing should be equal to look reasonable.
Adding an extra tick on the other plot helps, but the spacing looks
better without, so that's not an option. And switching back to the old
behavior means manually tweaking the distance, what makes no sense to me
either.
Thanks & best regards
Chris
