Hi,
I want to use special x-axis values like it's shown in
http://tug.org/PSTricks/main.cgi?file=pst-plot/psaxes#ChemElements.
My problem now is, that I have a datafile that I want to plot, and the
x-values are in the range from -0.5 to 0.5 and the x-axis should have
the values
-T/2 -T/4 0 T/4 T/2
The following does not work properly as the indexing of the label array
is wrong. How do I have to change the example?
\documentclass{scrartcl}
\usepackage[T1]{fontenc}
\usepackage{pstricks-add}
\makeatletter
\def\pst@@@hlabel#1{\small\textcolor{red}{\NewYLabels(#1)}}
\makeatother
\usepackage{arrayjob}
\usepackage{nicefrac}
\begin{document}
%
\newarray{\NewYLabels}
\readarray{NewYLabels}{\nicefrac{T}{2} & -\nicefrac{T}{4} & 0 &
\nicefrac{T}{4} & \nicefrac{T}{2}}
%
\psset{xunit=10cm}
\begin{pspicture}(-0.5,-3)(0.55,3)
\psset{Dx=0.25}
\psaxes{->}(-0.5,0)(-0.5,-3.5)(0.55,3.5)
\end{pspicture}
\end{document}
Thank you,
Christoph
