Hi Frank,

It seems to be a Problem with the number of decimal digits.
With 1.0, it works for me:

\documentclass{scrartcl}

\usepackage{pst-all}

\begin{document}
\begin{figure}
\begin{center}
\psgraph[Ox=-3.5,Oy=-3.5,Dx=1.0,Dy=1.0]{-}(-3.5,-3.5)(-3.5,-3.5)(0.5,0.5){5cm}{5cm}
\psdots[dotstyle=o, dotsize=6pt](-3.5,-3.5)(0.5,0.5)
\psdots[dotstyle=*, dotsize=6pt](0,0)
\endpsgraph
\end{center}
\end{figure}
\end{document}

Hope it works for you too.

Kind Regards,

Niklas
