pst-plot and psgraph environment to small

Question

I try to plot a large spectrum with pst-plot, but I cannot create a psgraph environment large enough, because the x-axis line is not drawn correctly.

Do you know how to make it work?

% !TeX program = xelatex
\documentclass[paper=A3,paper=landscape]{scrartcl}
\usepackage{pst-plot}
\usepackage[pass]{geometry}
\begin{document}
\psset{linewidth=0.1pt}
\begin{psgraph}(0,0)(10,10){20cm}{20cm}
\end{psgraph}
\end{document}

Answer 1

At the time I am writing this answer, PSTricks does not support hexadecimal number 2a0 in your {2a0cm}. So you need to remove the a as follows.

% !TeX program = xelatex
\documentclass[paper=A3,paper=landscape]{scrartcl}
\usepackage{pst-plot}
\usepackage[pass]{geometry}
\begin{document}
\psset{linewidth=0.1pt}
\begin{psgraph}(0,0)(10,10){20cm}{20cm}
\end{psgraph}
\end{document}

Answer 2

I cannot see this with up-to-date TL 2016. It looks like that you have a unit setting elsewhere ...
