适合横向模式的 8.5 英寸 x 11 英寸文档的福雷斯特层次结构图

Question

有没有办法使用图中层次结构图并将其加载到 latex 中，使其适合 8.5 英寸 x 11 英寸文档的横向布局，而不会影响页眉和页脚/页码？对 latex 来说还是有点陌生​​。我正在编写一个需要编码框架的文档，结果发现我的是分层的。但它只是 8.5 英寸 x 11 英寸纸张的一部分，上面的层次图被剪掉了。有什么想法吗？

Answer 1

一种方法是，但是您必须根据您的类别、页眉、页脚和页面布局进行调整。

修改了树的代码。另存为forest-hierarchical3.tex。

\documentclass[border=5pt,tikz]{standalone}

\usepackage{forest}
\usetikzlibrary{arrows.meta, shapes.geometric, calc, shadows}

\begin{document}
\colorlet{mygreen}{green!75!black}

\end{document}

然后你可以使用如下方法：

\documentclass[letterpaper]{article}
\usepackage[x11names,rgb]{xcolor}
\usepackage[vscale=.75]{geometry}
\usepackage{standalone}
\usepackage{rotating}
\usepackage{forest}
\usetikzlibrary{arrows.meta, shapes.geometric, calc, shadows}
\usepackage{fancyhdr}
\fancyhf[lh,ch,rh,lf,rf,cf]{Header/Footer}
\pagestyle{fancy}

\begin{document}
  \begin{sidewaysfigure}
    \centering
    \input{forest-hierarchical3}
  \end{sidewaysfigure}
\end{document}

创建以下内容：
