[pstricks] pst-fit

[Markus Krebs]

Dear all,

is there any easy way to change the font size and the decimal seperator
in listplot for the printed equation and the coefficient of determination?

Minimal working example:

\documentclass{article}
\usepackage{pst-fit,pstricks-add}
\begin{document}
\begin{filecontents}[overwrite]{linearbsp.dat}
5 1
3 4
4 2
6 1
2 7
\end{filecontents}
\readdata{\Linear}{linearbsp.dat}
\psset{unit=1cm}
\begin{pspicture}(-1,-1)(7,10)
\psaxes[showorigin=false]{->}(0,0)(-1,-1)(7,10)[$x$,270][$y$,0]
\psplot[algebraic,linecolor=gray,linestyle=dashed]{-1}{7}{9-1.5*x}
\listplot[plotstyle=dots,linecolor=red,dotscale=2,dotstyle=x]{\Linear}
\listplot[decimals=6,EqPos=5 6,plotstyle=GLLSR,
linestyle=solid,linecolor=blue,linewidth=1.5pt,comma]{\Linear}
\end{pspicture}
\end{document}

Thanks for any help in advance!
