pgfplots
I am using pgfplots to plot some data, but I am having problem you see in the image below. Basically, the ylabel overlaps with the axis numbering. I have googled a LOT but couldn't find any solution. Some people say that with versions >1.2 this should be automatically fixed, but even with 1.5.1 this is still happening to me…
Is there anyway to specify the location of the ylabel? Obviously I would like it to be a bit more to the left, so it does not overlap with the numbers.
Thanks!
In principle pgfplots provides what you need. Especially the x coord trafo section of the manual helps as Qrrbrbirlbel has mentioned.
Here is a very simple example:
\documentclass[tikz,12pt,preview]{standalone}
\usepackage{filecontents}
\begin{filecontents*}{transform.dat}
1 1
2 4
3 9
4 16
\end{filecontents*}
\usepackage{tikz,pgfplots}
\pgfplotsset{compat=1.8}
\usetikzlibrary{plotmarks,calc}
\begin{document}
\begin{tikzpicture}
\pgfplotsset{
x coord trafo/.code={\pgfmathparse{#1^2}\pgfmathresult},
x coord inv trafo/.code={\pgfmathparse{#1}\pgfmathresult},
}
\begin{axis}[ylabel={$f(x)=x^2$},xlabel=$x^2$]
\addplot table {transform.dat};
\end{axis}
\end{tikzpicture}
\end{document}
Here the x-axis is transformed and the final result is a straight line again:
In your code you are using rel axis cs: outside the axis environment which should not work (as expected). But you had the right idea to use a "relative" coordinate system to position the box. I suggest using axis description cs: to position it, because this is independent of xdir value.
For sure, both (rel axis cs: and axis description cs:) are better than the normal axis cs: because this always is dependent on the data you show. I personally only use it if I have to annotate a point in that (shown) coordinate system, but not for "general" annotations.
(I am sure there was already a question about this topic in the near past, but couldn't find it after a quick search.)

Quoting the manual, section 4.8.3 Labels:
In the following MWE, uncomment the
pgfplotssetline to see the difference.On the left, with
compat=1.5, on the right without:One could use
compat=newestto always use the newest version, but this could lead to issues with backwards compatibility, as future versions may behave differently. (See comment from Christian Feuersänger, author ofpgfplots, below.)
