Graphics, Figures & Tables ⇒ \pspicture always appears on new page

[Sagil]

I've tried to embed some pictures into a document, but find that they always appear on a separate page, in the bottom left corner. E.g. for the following simple document:

Code: Select all

\documentclass{article}
\usepackage{pstricks}
\usepackage{pst-plot}
\begin{document}
\begin{pspicture}[unit=2mm](0,0)(18,18)
\psaxes[Dx=2,Dy=2]{->}(18,18)
\psdots(4,7)(5,5)(7,4)
\end{pspicture}
\begin{pspicture}[unit=2mm](0,0)(18,18)
\psaxes[Dx=2,Dy=2]{->}(18,18)
\psdots(8,14)(10,10)(14,8)
\end{pspicture}
\end{document}

the two pictures appear on different pages. Anything wrong with the parameters I provide?

Edit: Nevermind, I got it - (18,18) parameters seem to indicate 18x18 cm, regardless of unit size..
