我有一个层次结构:
\begin{figure}[!h]
\begin{center}
\resizebox{\textwidth}{!}{%
\begin{tikzpicture}[level 1/.style={sibling distance=7cm},
level 2/.style={sibling distance=2cm},
level 3/.style={sibling distance=2.5cm}, align = flush center]
\tikzstyle{every node}=[draw,rectangle]
\node {Root}
[style=edge from parent fork down]
child {
node {1}
child {node {1.1}
child {node {1.1.1} }
child {node {1.1.2} }
child {node {1.1.3} }
}
child {node {1.2}}
child {node {1.3}}
}
child {
node {2}
child {node {2.1}}
child {node {2.2}
child {node {2.2.1} }
child {node {2.2.2} }
child {node {2.2.3} }
}
child {node {2.3}}
}
;
\end{tikzpicture}
}
\end{center}
\end{figure}
我想知道,我该如何更改我的乳胶,以便在图形的某些分支上贴上标签?例如,单词“left”将位于“Root”和“1”之间的分支上,单词“right”将位于“Root”和“2”之间的分支上。谢谢。

这可以通过 来完成edge from parent node
。请注意 已\tikzstyle
被弃用。
\documentclass[tikz,border=3.14mm]{standalone}
\usetikzlibrary{trees}
\begin{document}
\begin{tikzpicture}[level 1/.style={sibling distance=7cm},
level 2/.style={sibling distance=2cm},
level 3/.style={sibling distance=2.5cm}, align = flush center]
\tikzset{every node/.append style={draw,rectangle}}
\node {Root}
[style=edge from parent fork down]
child {
node {1}
child {node {1.1}
child {node {1.1.1} }
child {node {1.1.2} }
child {node {1.1.3} }
}
child {node {1.2}}
child {node {1.3}}
edge from parent node[pos=0.25,above,draw=none]{left}%<-added
}
child {
node {2}
child {node {2.1}}
child {node {2.2}
child {node {2.2.1} }
child {node {2.2.2} }
child {node {2.2.3} }
}
child {node {2.3}}
edge from parent node[pos=0.25,above,draw=none]{right}%<-added
}
;
\end{tikzpicture}
\end{document}
有了森林,这项事业可以说变得更加简单。
\documentclass[tikz,border=3.14mm]{standalone}
\usepackage[edges]{forest}
\begin{document}
\begin{forest}
for tree={grow=south,draw,s sep=2em},
forked edges
[Root
[1,edge label={node[pos=0.35,above]{left}}
[1.1
[1.1.1]
[1.1.2]
[1.1.3]
]
[1.2]
[1.3]
]
[2,edge label={node[pos=0.35,above]{right}}
[2.1]
[2.2
[2.2.1]
[2.2.2]
[2.2.3]
]
[2.3]
]
]
\end{forest}
\end{document}
