Why cannot XeLaTeX clip my PSTricks graph plot correctly?

Question

The following screenshot produced by latex-dvips-ps2pdf and the clipping is well done.

\documentclass{article}
\usepackage{xcolor}
\usepackage{pstricks,pst-func}

\newpsstyle{gridstyle}
{
gridwidth=0.4pt,%default: 0.8pt
gridcolor=red!20,%default: black
griddots=0,%default: 0 
%
gridlabels=3pt,%default: 10pt
gridlabelcolor=blue,%default: black
%
subgriddiv=5,%default: 5
subgridwidth=0.2pt,%default: 0.4pt
subgridcolor=green!20,%default: gray
subgriddots=0%default: 0
}

\psset{style=gridstyle}
\newpsobject{psGrid}{psgrid}{}

\begin{document}
\noindent%
\renewcommand{\pshlabel}[1]{\bfseries\tiny #1}% for x-axis
\renewcommand{\psvlabel}[1]{\bfseries\tiny #1}% for y-axis
\psset{yunit=0.4cm,xunit=0.5cm}
\centering\begin{pspicture*}(-4,-5)(4,15)
    \psGrid
    \psaxes[Dy=2,Dx=2]{<->}(0,0)(-4,-5)(4,15)
    \psset{linewidth=1pt,linecolor=blue}
    \psPolynomial[coeff=-1 0 1,linecolor=red]{-4}{4}    
    \psPolynomial[coeff=-1 0 1,xShift=1,linestyle=dashed]{-4}{4}    
    \rput[rt](3,12){\textcolor{red}{$f(x)$}}
    \rput[lt](2.5,1){\textcolor{blue}{$g(x)$}}  
\end{pspicture*}
\end{document}

But the following screenshot produced by xelatex and the clipping is bad done

Why cannot XeLaTeX clip my PSTricks graph plot correctly?

Last edit: After updating Miktex packages, xelatex clips the graph correctly.

Answer 1

I can confirm the problem. Clipping doesn't work with xetex at all in miktex. Even with such a simple example like this:

\documentclass{article}
\usepackage{pstricks}

\begin{document}
abc\begin{pspicture*}(1,1)
\psline(-1,-1)(2,2)
\end{pspicture*}abc

\end{document}

I don't think that the version of the xdvipdfmx.cfg is the problem. Miktex use the same version as the one on CTAN (Version 0.02 (2010/08/02)). Also the miktex ghostscript isn't responsable either, it doesn't help if I change to gswin32c.

The problem doesn't seem to be new: I can reproduce it in my old miktex 2.7 (xdvipdfmx version is 0.7.3).

Answer 2

I cannot see any problem with running xelatex under TeXLive2010 and Linux. However, here is a shorten variant of your code:

\documentclass{article}
\usepackage{pst-func}

\newpsstyle{gridstyle}{
gridwidth=0.4pt,%default: 0.8pt
gridcolor=red!20,%default: black
griddots=0,%default: 0 
%
gridlabels=0pt,%default: 10pt
gridlabelcolor=blue,%default: black
%
subgriddiv=5,%default: 5
subgridwidth=0.2pt,%default: 0.4pt
subgridcolor=green!20,%default: gray
subgriddots=0%default: 0
}

\begin{document}
\noindent%
\psset{yunit=0.4cm,xunit=0.5cm}
\centering\begin{pspicture*}[showgrid](-4,-5)(4,15)
    \psaxes[Dy=2,Dx=2,labelFontSize=\bfseries\tiny,mathLabel=false]{<->}(0,0)(-4,-5)(4,15)
    \psset{linewidth=1pt,linecolor=blue}
    \psPolynomial[coeff=-1 0 1,linecolor=red]{-4}{4}    
    \psPolynomial[coeff=-1 0 1,xShift=1,linestyle=dashed]{-4}{4}    
    \rput[rt](3,12){\textcolor{red}{$f(x)$}}
    \rput[lt](2.5,1){\textcolor{blue}{$g(x)$}}  
\end{pspicture*}

\end{document}
