no problem with PSTricks ...


\documentclass[pstricks]{standalone}
\usepackage{pst-plot}
\makeatletter
\def\psdots at iii{%
   \psk at dotsize
   \@nameuse{psds@\psk at dotstyle}
   \tx at setStrokeTransparency
   newpath
   n { transform floor .5 add exch floor .5 add exch
       itransform Dot  } repeat }
\makeatother
\begin{document}

\def\al{0.007133}
\def\be{13.76 }

\psset{llx=-1,lly=-0.75,urx=0.5,ury=0.5,arrows=->}
\pstScalePoints(1,1){1000 div}{}
\begin{psgraph}[Oy=30,Dy=10,Ox=3,xlabelFactor=\cdot10^3](3,30)(10,100){10cm}{10cm}
\readdata{\Data}{data.dat}
\pslistplot[plotstyle=dots,dotscale=0.5,linecolor=blue,strokeopacity=.4]{\Data}
\psplot[algebraic,plotpoints=2]{3.7}{9.4}{\al*x*1000+\be}
\end{psgraph}

\end{document}

The modification will be available in the next PSTricks update.
