Patrice,
this is the default behaviour of _PSTricks_, it takes only the \psunit
into acount, but not \psxunit and \psyunit for the three makros.
Compare the following two examples. The first one will also be correct,
if you use \psset{unit=5cm}. And with \psgraph you can write simply
\let\psunit\psxunit (see example).

\documentclass{article}
\usepackage{pstricks-add}
\begin{document}

\psset{xunit=5cm,yunit=5cm}
%\psset{unit=5cm}
\begin{pspicture}{->}(-1.1,-1.1)(1.1,1.1)
\psaxes[Dx=0.2,Dy=0.2]{->}(0,0)(-1.1,-1.1)(1.1,1.1)
\psarc[linecolor=green](0,0){1}{0}{90}
\pscircle[linecolor=red]{1}
\psellipse(1,0.5)
\psline(1,1)(0,0.5)
\psframe(0.5,0.5)(1,1)
\pswedge[linecolor=blue]{1}{0}{45}
\end{pspicture}

\begin{psgraph}[Dx=0.2,Dy=0.2]{->}(0,0)(-1.1,-1.1)(1.1,1.1){10cm}{10cm}
\let\psunit\psxunit
\psarc[linecolor=green](0,0){1}{0}{90}
\pscircle[linecolor=red]{1}
\psellipse(1,0.5)
\psline(1,1)(0,0.5)
\psframe(0.5,0.5)(1,1)
\pswedge[linecolor=blue]{1}{0}{45}
\end{psgraph}

\end{document}
