森林边缘的特殊符号/颜色

我正在研究森林，这是迄今为止我构建的树的一部分：

我正在尝试创建您在附图中看到的树的这一部分。如何将图片中显示的符号添加到边缘？此外，如何使边缘显示不同的颜色？

Answer 1

将您的示例修剪为仅需要的包，您可以定义一个边缘样式（此处称为xedge），它在边缘上添加井号标记并使其和其下方的其余节点变为灰色。

我已将其替换\sc为\scshape（见双字母字体样式命令 (\bf，\it，...) 会在 LaTeX 中复活吗？）我还为你的wiggly风格添加了一个来源，它来自另一个答案在网站上。

对于以后的问题，请构建最小实际编译的示例，并给出适当的代码归属。

\documentclass{article}

\def\textgamma{$\gamma$}
\forestset{
grayed/.style={for tree={gray,edge=gray}},
xedge/.style={grayed,edge path={\noexpand\path[\forestoption{edge}](!u.parent anchor)-- node[sloped,rotate=90,text={black}] {=} (.child anchor)\forestoption{edge label};}},
% following style from https://tex.stackexchange.com/a/326392/
  /tikz/squiggly/.style={decorate, decoration={snake, amplitude=.5mm, segment length=2mm}},
  wiggly/.style={edge=squiggly},
  move me/.style n args=2{%
    before drawing tree={%
      x+=#1,
      y+=#2,
    },
  },
}
