我正在forest为一份报告绘制酶/底物的水平图。在我的实际standalone文件中，它目前的样子如下：
我想使用standalone以便可以添加引用和工作超链接。但是，包含文本的框太高，相对不重要的图形占用了主报告文档中的太多空间。我已经尝试过s sep等，但因为我认为这是个tikz问题（即文本框的高度），所以我不确定该怎么做，因为我最近才开始学习tikz。我绝对不知道如何forest与 交互tikz以设置node至少。
请问我怎样才能控制包含“马肝醇 DH”的框的高度node（例如）并减少单词上方和下方的空间？
我的 MWE 如下所示：

您可以添加inner ysep=1pt（或任意长度）到for tree。
\documentclass[border=0mm]{standalone}
\usepackage{forest}
\useforestlibrary{edges}
\usetikzlibrary{arrows,arrows.meta,automata,backgrounds,calc,

\usepackage[hidelinks]{hyperref}
\begin{document}
\newcommand\hyperlinkStuff[2]{\scalebox{0.75}{\tiny(\color{blue}{\href{#1}{#2}}\color{black}{)}}}
\begin{forest}

如您所见，节点之间的垂直距离由 设定s sep=1pt（在代码中用 标记<--）。您可以根据需要更改距离的大小。
编辑：
显然，由于某些未知的原因，您更喜欢节点的边界紧贴文本，并且节点具有垂直距离，例如如下所示：
对于这个（丑陋的）结果你需要for tree添加选项：
inner ysep = 0.5pt, outer ysep=0pt,
并改为s sep = 1pt`s sep = 0pt。
