# Adding child nodes to child nodes in TikZ Mindmap

I'm trying to build a mind map in TikZ and am having numerous problems.

I have only a very basic grasp of TeX and would like some help.

I found a source and replaced text to create my first steps.

Now I'd like:

1. To add child nodes to my child nodes

2. A bigger canvas

How do I do them?

Source code:

\documentclass{article}

\usepackage{tikz}
\usetikzlibrary{mindmap,trees}

\begin{document}
\begin{tikzpicture}
\path[mindmap,concept color=black,text=white]
node[concept] {Die Wahrnehmung}
[clockwise from=0]
child[concept color=green!50!black] {
node[concept] {Sensorische Prozesse}
[clockwise from=90]
child { node[concept] {Sinnes\-organe} }
child { node[concept] {Schwellen}
child {node[concept] {absolute Schwelle}}
child {node[concept] {Unterschiedsschwelle}}
}
child { node[concept] {Optische Täuschungen aufgrund sensorischer Prozesse}
}
}
child[concept color=blue] {
node[concept] {Organisation}
[clockwise from=-30]
child { node[concept] {Hauptsatz} }
child { node[concept] {Gestaltgesetze} }
}
child[concept color=red] { node[concept] {Klassifikation} };
\end{tikzpicture}
\end{document}

I have fixed the code and added the image but I am not sure if that was your actual question. So please let us know if I edited a little too much. –  percusse Feb 23 '12 at 11:21
No, that's exactly what I need! Thanks, let me try a bit further and report back with the next problem… –  Edd Turner Feb 23 '12 at 11:26
Oh, please ask a new question. You are definitely welcome to ask follow-up questions as seperate questions. Moreover, you can link to this question in your new ones. –  percusse Feb 23 '12 at 11:29
OK, my new question is tex.stackexchange.com/questions/45515/… –  Edd Turner Feb 23 '12 at 12:14
You may want to load \usepackage[utf8x]{inputenc} to support Umlaute, and may want to have a look at tex.stackexchange.com/questions/45517/… for automatic hyphenation of German words. –  Unapiedra Feb 23 '12 at 12:23

Just nest further, add children after nodes. The tikzpicture canvas will be extended. Here's a small example with four levels. You can extend it, add and modify styles.

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{mindmap}
\begin{document}
\begin{tikzpicture}
\path[mindmap,concept color=blue,text=white,
level 1 concept/.append style=
{every child/.style={concept color=blue!70},sibling angle=-30}]
node[concept] {\Huge\bfseries PGF}[clockwise from=0]
child {node[concept]{\LARGE Ti\emph{k}Z}
child{node[concept] {\large arrows}
child {node[concept] {thick}}
child {node[concept] {thin}}}
child{node[concept] {\large mindmap}}
child{node[concept] {\large plots}} };
\end{tikzpicture}
\end{document}
