    Hi,<br>
    <br>
    <span style="white-space: pre;">> are you looking for something
      like this?<br>

    <br>
    definitely something that looks like that. Isn't there a more proper
    way<br>
    to do it with many points (>1000) with dots all having the same
    size ?<br>
    <br>
    <span style="white-space: pre;">> If not provide a _complete_
      example including a small data set</span><br>
    <br>
    I am trying to do something like this:<br>
    <br>
    \def\xmin{3700}<br>
    \def\ymin{31}<br>
    \def\xmax{9400}<br>
    \def\ymax{103}<br>
    \def\dx{2500}<br>
    \def\dy{25}<br>
    \def\al{0.007133}<br>
    \def\be{13.76}<br>
    \begin{pspicture}<br>
\begin{psgraph}[Ox=\xmin,Oy=\ymin,Dx=\dx,Dy=\dy](\xmin,\ymin)(\xmax,\ymax){5cm}{5cm}<br>
\psfileplot[plotstyle=dots,dotscale=.5,linecolor=blue,strokeopacity=.2]{data.dat}<br>
    \psplot[algebraic,plotpoints=2]{\xmin}{\xmax}{\al*x+\be}<br>
    \end{psgraph}<br>
    \end{pspicture}<br>
    <br>
    where the data set can be found at<br>
    <br>

    <br>
    Sorry for compilation time (5871 points), but I guess data size
    matters here.<br>
    <br>
    best,<br>
