用森林生成的水平图紧密贴合

我使用 forest 包创建了类似下图的图表。 有没有可能缩短 B5 和 B6 之间的距离？ 我更希望 B6 及其子树可以向上移动。到目前为止，我已经尝试了l、s、l sep和选项s sep，但都没有成功。 实际上，我认为默认值应该可以完成这项工作，但事实并非如此...fitfit=tight

在此处输入图片描述

\documentclass{standalone}
\usepackage{forest}

\begin{forest}
for tree={fit=tight}

[E1, for tree={grow=south},

说实话，我不确定这是否是一个很大的改进。但是，它更清楚地说明了发生了什么，代码也更加简洁。它也稍微紧凑了一些（宽度和高度/深度都比 OP 的解决方案要小）。当然，这一切是否重要是另一回事。
