[pstricks] I need some advise for a generic drawing

Great :-)

Hmm, you are right. Actually after thinking a bit more about it i 
realised that something like:

<--- dendrit.tex --->

\documentclass{article}

\usepackage{pstricks}
\usepackage{multido}

\newcommand{\dendrit}[6][]{%
\psline[#1](0,0)(0,#2)
\multido{\na=#4+-#5,\nb=0.4+#6}{#3}{%
\rput[c](0,\nb){\psline[#1](-\na,0)(\na,0)}}}

\pagestyle{empty}

\begin{document}

\begin{pspicture}(0,0)(6,4)
    
     \rput(0,0){\dendrit[linecolor=red,linestyle=dashed]{2}{4}{0.8}{0.1}{0.4}}
    
     \rput(2,0){\dendrit{2}{4}{1}{0.2}{0.4}}
    
     \rput(4.5,0){\dendrit[linecolor=blue]{3}{6}{1.2}{0.15}{0.5}}
   
\end{pspicture}

\end{document}

<-------->

should do the job. I thought that i could find some rules which 
determine the distances and length, etc. but it's much easier to make 
it a parameter and check what looks best for the current purpose. At 
the moment it will become only a small feature in a already existing 
picture therefore is should not waste too much time on it.

Nevertheless thanks
   Martin
