some small modifications:

\documentclass{scrartcl}
\usepackage{pst-plot}
\begin{document}

\psset{unit=.8cm,plotpoints=500}
\begin{pspicture}(-1,-3)(11,7)
   \psaxes[arrowscale=2,Dx=20,dx=2,Dy=20,dy=2,subticks=10,
   ,ticklinestyle=dashed,yticksize=0 10,xticksize=-3 7,
   tickcolor=black!50,subtickcolor=black!20,
   subticksize=1]{->}(0,0)(0,-3)(10.5,7.5)[$x$,-90][$y$,180]
   \psplot[linewidth=1.5pt,algebraic,
           linecolor=red]{0}{10}{4*sin(Pi/2.5*x)+2}
\end{pspicture}

\end{document}
