[pstricks] Question aboout pst-plot

[azzam.hassan at voila.fr]

Hi
here below my pstricks code
\begin{center}
\def\f{x^2-2}
\def\fDerive{2*x}
\psset{plotpoints=100,algebraic,xunit=2cm,yunit=.5cm}
\psset[pst-plot]{fontscale=10,valuewidth=10,decimals=-1}
%
\begin{pspicture*}[showgrid](-3,-5)(3.5,5)
\psaxes[labelFontSize=\scriptstyle]{->}(0,0)(-3,-3)(3,4.5)[$x$,0][$y$,0]
\psplot[linewidth=2pt,linecolor=blue]{-1}{3}{\f}
\uput[270](2.5,-0.1){$x_0=2.5$} %\uput[90](3.9,0){$x_0$}
\psNewton[linecolor=red,linewidth=0.5pt,%plotstyle=xvalues,
showDerivation=false]{2.5}{\f}{3}
\psNewton[showpoints=true,dotsize=5pt,dotstyle=o,plotstyle=xvalues,linestyle=dashed]{2.5}{\f}{4}
\rput*(0,-3.5){M{\'e}thode de Newton: R{\'e}solution de $x^2-2=0$}
\end{pspicture*}
\end{center}

I would make the xvalues on the plot, smaller
