The following example from pst-3dplot does not give me perpendicular
axes.
\usepackage{pst-3dplot}
\begin{document}
\begin{pspicture}(-2,-2)(2,2)
\pstThreeDCoor
\psgrid
\end{pspicture}
Instead, the z-axis is not vertical, and it does not intersect with
the x and y axes at their intersection point. Am I missing something
simple here?
