I used to make a chain diagram in tikz, like described in the manual p. 59 ff, but in contrast to the manual, my nodes are overlapping. I tried to use the "node distance" option but i doesn't seem to work. Below is the minimal working example (writeLatex.com):
\documentclass[12pt]{scrartcl}
\usepackage{tikz}
\begin{document}
\begin{figure}[tb]
\begin{center}
\begin{tikzpicture}[
% copy to preamble to use it everywhere \tikzset{node/.style...}
node/.style={
% shape
rectangle,
rounded corners=1mm,
minimum size=6mm,
%border
thick,
draw,
},
dummy/.style={
% shape
rectangle,
rounded corners=1mm,
minimum size=6mm,
%border
thick,
},
node distance=10mm
]
\node(wadl)[node]{WADL-Datei};
\node(xsd1)[node,below left of=wadl]{XSD-Datei};
\node(...)[dummy,below of=wadl]{\ldots};
\node(xsd3)[node,below right of=wadl]{XSD-Datei};
\node(test)[node,right of=wadl]{test};
\path(wadl) edge[->] (test);
\end{tikzpicture}
\end{center}
\caption{Codegeneratorsystem}
\label{fig:codegeneratorsystem}
\end{figure}
\end{document}



chainslibrary (which uses the superiorpositioninglibrary automatically and can simplify the creation of chain diagrams in certain aspects). Also, a node name of...calls for trouble as TikZ uses the.to separate node name and node anchor in the implicit node coordinate syntax. You won’t be able to reference any of...’s anchors nor use it with thepositioninglibrary as a reference node. – Qrrbrbirlbel Jun 18 '13 at 16:13
