在 Latex 中将垂直树转换为水平树

Question

我想使用 tikz 绘制下面的树。

但我已经以垂直格式绘制了树。

有没有办法将上面的图水平转换？

Answer 1

您可以使用选项grow=east。forest有关选项的更多信息以及如何使用选项为节点及其所有后代设置选项，请参阅手册for tree：

\documentclass[a4paper, 10pt]{report}
\usepackage [edges, linguistics]{forest} % for drawing forest

\begin{document}
\begin{center}
  \begin{forest}
    for tree={grow=east},
    forked edges
 [a
 [b][c[d][e]]]]
\end{forest}
\end{center}
\end{document}

或者使用grow'=east设置reverse为true而不是false：

\documentclass[a4paper, 10pt]{report}
\usepackage [edges, linguistics]{forest} % for drawing forest

\begin{document}
\begin{center}
  \begin{forest}
    for tree={grow'=east},
    forked edges
 [a
 [b][c[d][e]]]]
\end{forest}
\end{center}
\end{document}

注意：手册还解释了grow''，它不会改变reverse。在示例中，它将显示与 相同的结果grow。
