Baumdiagramm beschriften

**lutz** · 22-11-2012, 15:51

Hallo zusammen!

Wie kann ich die einzelnen Äste des Baumdiagramms mit Brüchen beschriften?

Code:

\documentclass{article}
\usepackage[ngerman]{babel}
\usepackage[utf8]{inputenc}
\usepackage{tikz}
\usetikzlibrary{trees}
\usepackage{verbatim}
\pagestyle{empty}
\begin{document}
\tikzstyle{bag} = [text width=4em, text centered]
\tikzstyle{end} = [circle, minimum width=0pt,fill, inner sep=0pt]
\begin{tikzpicture}[level distance=20mm]
\tikzstyle{level 1}=[sibling distance=5cm]
\tikzstyle{level 2}=[sibling distance=3cm]
\tikzstyle{level 3}=[sibling distance=1.5cm]
\node {}
child {node {A} 		
child {node {E}
child{node{L}
}
}
child {node {L}
child{node{E}
} 								
}
}
child {node {E}  							
child {node {A}
child{node{L}
}						
}
child {node {L} 									
child{node{A}
}
}
}
child {node {L}  							
child {node {A}	
child{node{E}
}					
}
child {node {E} 									
child{node{A}
}
}
}
;
\end{tikzpicture}
\end{document}

Wenn ich einfach

edge from parent node[left] {$\frac{1}{3}$}

dranhänge, dann zerschießt es mir den Bau, siehe

Code:

\documentclass{article}
\usepackage[ngerman]{babel}
\usepackage[utf8]{inputenc}
\usepackage{tikz}
\usetikzlibrary{trees}
\usepackage{verbatim}
\pagestyle{empty}
\begin{document}
\tikzstyle{bag} = [text width=4em, text centered]
\tikzstyle{end} = [circle, minimum width=0pt,fill, inner sep=0pt]
\begin{tikzpicture}[level distance=20mm]
\tikzstyle{level 1}=[sibling distance=5cm]
\tikzstyle{level 2}=[sibling distance=3cm]
\tikzstyle{level 3}=[sibling distance=1.5cm]
\node {}
child {node {A} 	
	edge from parent node[left] {$\frac{1}{3}$} 
child {node {E}
child{node{L}
}
}
child {node {L}
child{node{E}
} 								
}
}
child {node {E}  							
child {node {A}
child{node{L}
}						
}
child {node {L} 									
child{node{A}
}
}
}
child {node {L}  							
child {node {A}	
child{node{E}
}					
}
child {node {E} 									
child{node{A}
}
}
}
;
\end{tikzpicture}
\end{document}

hi,

an der richtigen stelle und mit der kleinen aber feinen veraenderung draw=none geht es

Code:

\documentclass{article}
\usepackage[ngerman]{babel}
\usepackage[utf8]{inputenc}
\usepackage{tikz}
\usetikzlibrary{trees}
\usepackage{verbatim}
\pagestyle{empty}
\begin{document}
\tikzstyle{bag} = [text width=4em, text centered]
\tikzstyle{end} = [circle, minimum width=0pt,fill, inner sep=0pt]
\begin{tikzpicture}[level distance=20mm]
\tikzstyle{level 1}=[sibling distance=5cm]
\tikzstyle{level 2}=[sibling distance=3cm]
\tikzstyle{level 3}=[sibling distance=1.5cm]
\node {Root}
child {node {A} edge from parent node[above,draw=none] {$\frac{1}{3}$}}	
child {node {E}
child{node{L}
}
child {node {L}
child{node{E}
} 								
}
}
child {node {E}  							
child {node {A}

Hallo!

hi,

Allerdings rutschen dann die nächsten "Kinder"-Kategorie eine Ebene nach rechts. Ich hätte die gerne unterhalb der "Eltern"-Kategorie "A".

So klappt es aber auch nicht, da dann die Kinder an die Beschriftung 1/3 angehängt sind:

Code:

\documentclass{article}
\usepackage[ngerman]{babel}
\usepackage[utf8]{inputenc}
\usepackage{tikz}
\usetikzlibrary{trees}
\usepackage{verbatim}
\pagestyle{empty}
\begin{document}
\tikzstyle{bag} = [text width=4em, text centered]
\tikzstyle{end} = [circle, minimum width=0pt,fill, inner sep=0pt]
\begin{tikzpicture}[level distance=20mm]
\tikzstyle{level 1}=[sibling distance=5cm]
\tikzstyle{level 2}=[sibling distance=3cm]
\tikzstyle{level 3}=[sibling distance=1.5cm]
\node {Root}
child {node {A} edge from parent node[above,draw=none] {$\frac{1}{3}$}
child {node {E}
child {node{L}
}
}
child {node {L}
child{node{E}
} 								
}
}
child {node {E}  							
child {node {A}
child{node{L}
}						
}
child {node {L} 									
child{node{A}
}
}
}
child {node {L}  							
child {node {A}	
child{node{E}
}					
}
child {node {E} 									
child{node{A}
}
}
}
;
\end{tikzpicture}
\end{document}

Hallo,
wenn das 1/3 an den Ast von "root" zu "child A" geschrieben werden soll, dann muss das "edge from parent node" direkt vor der schließenden Klammer des "child A" geschrieben werden.

Code:

\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{trees}
\pagestyle{empty}
\begin{document}
\begin{tikzpicture}[level distance=20mm]
\tikzstyle{level 1}=[sibling distance=5cm]
\tikzstyle{level 2}=[sibling distance=3cm]
\tikzstyle{level 3}=[sibling distance=1.5cm]
\node {root}
  child {node {child A}
    child {node {E}
      child{node{L}
      }
    }
    child {node {L}
      child{node{E}
      }
    }
  edge from parent node[above] {$\frac{1}{3}$}}
  child {node {E}
    child {node {A}
      child{node{L}
      }
    }
    child {node {L}
      child{node{A}
      }
    }
  }
  child {node {L}
    child {node {A}
      child{node{E}
      }
    }
    child {node {E}
      child{node{A}
      }
    }
  }
;
\end{tikzpicture}
\end{document}

Hallo!

Zitat von esdd

wenn das 1/3 an den Ast von "root" zu "child A" geschrieben werden soll, dann muss das "edge from parent node" direkt vor der schließenden Klammer des "child A" geschrieben werden.

Prima vielen Dank für den Tipp, jetzt funktioniert es.

Code:

\documentclass{article}
\usepackage[ngerman]{babel}
\usepackage[utf8]{inputenc}
\usepackage{tikz}
\usetikzlibrary{trees}
\usepackage{verbatim}
\pagestyle{empty}
\begin{document}
\tikzstyle{bag} = [text width=4em, text centered]
\tikzstyle{end} = [circle, minimum width=0pt,fill, inner sep=0pt]
\begin{tikzpicture}[level distance=20mm]
\tikzstyle{level 1}=[sibling distance=5cm]
\tikzstyle{level 2}=[sibling distance=3cm]
\tikzstyle{level 3}=[sibling distance=1.5cm]
\node {}
child {node {A} 
child {node {E}
child {node{L}
edge from parent node[left,draw=none] {$1$}}
edge from parent node[above,draw=none] {$\frac{1}{2}$}}
child {node {L}
child{node{E}
edge from parent node[right,draw=none] {$1$}} 								
edge from parent node[above,draw=none] {$\frac{1}{2}$}}
edge from parent node[above,draw=none] {$\frac{1}{3}$}}
child {node {E}  							
child {node {A}
child{node{L}
edge from parent node[left,draw=none] {$1$}}						
edge from parent node[above,draw=none] {$\frac{1}{2}$}}
child {node {L} 									
child{node{A}
edge from parent node[right,draw=none] {$1$}}
edge from parent node[above,draw=none] {$\frac{1}{2}$}}
edge from parent node[left,draw=none] {$\frac{1}{3}$}}
child {node {L}  							
child {node {A}	
child{node{E}
edge from parent node[left,draw=none] {$1$}}					
edge from parent node[above,draw=none] {$\frac{1}{2}$}}
child {node {E} 									
child{node{A}
edge from parent node[right,draw=none] {$1$}}
edge from parent node[above,draw=none] {$\frac{1}{2}$}}
edge from parent node[above,draw=none] {$\frac{1}{3}$}}
;
\end{tikzpicture}
\end{document}

Noch eine Schönheitskorrektur: Die Brüche kleben in der 2. Ebene noch zu sehr an den Linien. Wie kann ich dies korrigieren?

**hakaze** · 23-11-2012, 10:08

Du kannst die nodes auch noch etwas mit xshift/yshift verschieben, zum Beispiel:

Code:

edge from parent node[above,draw=none,xshift=-2pt] {$\frac{1}{2}$}} % 2 pt nach links verschieben

**esdd** · 23-11-2012, 10:34

Oder du verwendest bei den schrägen Ästen einfach above left bzw. above right.

Code:

edge from parent node[above left] {$\frac{1}{2}$}}

Das draw=none ist übrigens nicht notwendig.
