[pstricks] labels and 3dplot

[Markus Krebs]

Hi!

Is there any possibility to change label-style in 3d-plot? The decimals are 
not necesary.

\documentclass[12pt,landscape,xcolor={svgnames,dvipsnames},trans]{beamer}
\usepackage{pstricks,pst-vue3d,pst-3dplot,pstricks-add,pst-xkey}
\psset{unit=0.4}
\begin{pspicture}(-19,-10)(9,10)
\psset{xMin=0,
           yMin=0,
           zMin=0,
           xMax=20,
           yMax=10,
           zMax=10,
          Alpha=40,
          Beta=30,
          nameX=$x_1$,
          nameY=$x_2$,
          nameZ=$x_3$,
         IIIDticks=true,
         linewidth=2pt}%
\pstThreeDCoor[drawing=true,IIIDticksize=.25]
\psset{linewidth=0.25pt,linecolor=gray}
\pstThreeDPlaneGrid[xsubticks=20,ysubticks=10](0,0)(20,10)
\pstThreeDPlaneGrid[ysubticks=10,xsubticks=20,planeGrid=xz](0,0)(20,10)
\pstThreeDPlaneGrid[subticks=10,planeGrid=yz](0,0)(10,10)
\end{pspicture}
\end{document}

Thanks in advance!
