Text Formatting ⇒ Adjusting text in family tree nodes

[anta40]

Let's say we have this hypothetical family tree

Code: Select all

\documentclass{beamer}
\usepackage{tikz}
\usepackage{verbatim}
%\usepackage[active,tightpage]{preview}
%\PreviewEnvironment{tikzpicture}
%\setlength\PreviewBorder{15pt}%
\usetheme{default}
\usetikzlibrary{trees}
\begin{document}


\begin{frame}{Hello}

A fictionary family tree

\begin{center}
\begin{tikzpicture}[
  man/.style={rectangle,draw,fill=blue!20},
  woman/.style={rectangle,draw,fill=red!20,rounded corners=.8ex},
  grandchild/.style={grow=down,xshift=1em,anchor=west,
    edge from parent path={(\tikzparentnode.south) |- (\tikzchildnode.west)}},
  first/.style={level distance=6ex},
  second/.style={level distance=12ex},
  third/.style={level distance=18ex},
  level 1/.style={sibling distance=5em}]
    % Parents
    \coordinate
      child[grow=left] {node[man,anchor=east]{Cyrus the Great}}
      child[grow=right] {node[woman,anchor=west]{Elizabeth}}
      child[grow=down,level distance=0ex]
    [edge from parent fork down]
    % Children and grandchildren
    child{node[man] {John the Conqueror}}
    child{node[man] {Ivan the Terrible}}
    child {node[woman] {Joanne of Arc}}
    child {node[man] {Richard Lionheart}}
    child {node[woman]{Mata Hari}};
\end{tikzpicture}
\end{center}
\end{frame}



\end{document}

Due to long names, the nodes will be jammed like this. So I have several questions in mind:
1. How to insert linebreaks into the nodes?
2. How to adjust the fonst size?
3. How to adjust the distance between nodes?

Thank you

You can do all this by modifying styles.

1. You can use \\, but add an alignment option, such as align=center.
2. Add an option such as font=\small.
3. Adjust a distance value, such as level 1/.style={sibling distance=6em}].

A complete example with the changes:

Code: Select all

\documentclass{beamer}
\usepackage{tikz}
\usepackage{verbatim}
%\usepackage[active,tightpage]{preview}
%\PreviewEnvironment{tikzpicture}
%\setlength\PreviewBorder{15pt}%
\usetheme{default}
\usetikzlibrary{trees}

  grandchild/.style={grow=down,xshift=1em,anchor=west,
    edge from parent path={(\tikzparentnode.south) |- (\tikzchildnode.west)}},
  first/.style={level distance=6ex},
  second/.style={level distance=12ex},
  third/.style={level distance=18ex},
  level 1/.style={sibling distance=5em}]
    % Parents
    \coordinate
      child[grow=left] {node[man,anchor=east]{Cyrus the Great}}
      child[grow=right] {node[woman,anchor=west]{Elizabeth}}
      child[grow=down,level distance=0ex]
    [edge from parent fork down]
    % Children and grandchildren
    child{node[man] {John the\\Conqueror}}
    child{node[man] {Ivan the\\Terrible}}
    child {node[woman] {Joanne\\of Arc}}
    child {node[man] {Richard\\Lionheart}}
    child {node[woman]{Mata\\Hari}};
\end{tikzpicture}
\end{center}
\end{frame}
