森林本地风格与全球风格

这件事让我沮丧了一两个小时。通常我会在每张图片中局部维护森林风格。有一片森林让我抓狂不已，但我确信我做的事情完全是愚蠢的。

下面的 MWE 可以按原样编译，但当注释掉 tikzset 并且取消注释两个相同的注释行时，将无法编译。为什么不行？错误是“我不知道密钥 '/tikz/belowab”

\documentclass{article}
\usepackage{forest}

\begin{document}

\tikzset{
aboveab/.style={midway,  above,  font=\scriptsize,  text width=1.5cm,  align=center},
belowab/.style={midway,  below,  font=\scriptsize,  text width=1.5cm,  align=center}}

\begin{forest} 
%aboveab/.style={midway,  above,  font=\scriptsize,  text width=1.5cm,  align=center},
%belowab/.style={midway,  below,  font=\scriptsize,  text width=1.5cm,  align=center},
for tree={
  grow=east,
  draw=blue,
  circle,
  line width=0.2pt,
  parent anchor=east,
  child anchor=west,
  edge={draw=blue},
  edge label={\Huge\color{black}},
  edge path={
    \noexpand\path[\forestoption{edge}]
      (!u.parent anchor) -- ([xshift=-1.6cm].child anchor) --    
      (.child anchor)\forestoption{edge label};
  },
  l sep=2cm,
} 
[,rectangle, s sep=35pt,
  [,edge label={node[belowab]{Text}}
    [,edge label={node[belowab]{Text}}
    ]
    [,edge label={node[aboveab]{Text}}
    ]
  ]
  [,edge label={node[aboveab]{Text}}
    [,edge label={node[belowab]{Text}}
    ]
    [,edge label={node[aboveab]{text}}
    ]
  ]
]
\end{forest}

\end{document}

但是，以下形式的森林前缀将起作用

\begin{forest}
parentab/.style={align=center,text width=2cm,fill=green!20,rounded corners=2pt},
childab/.style={align=center,text width=3.5cm,fill=green!50,rounded corners=6pt},
grandchildab/.style={fill=pink!50,text width=3.3cm},
for tree={%
    thick,
    drop shadow,
    l sep=0.6cm,
    s sep=0.8cm,
    node options={draw,font=\sffamily},
    edge={semithick,-Latex},
    where level=0{parentab}{},
    where level=1{
        minimum height=1cm,
        childab,
        parent anchor=south west,
        tier=p,
        l sep=0.25cm,
        for descendants={%
            grandchildab,
            minimum height=0.6cm,
            anchor=150,
            edge path={
                \noexpand\path[\forestoption{edge}]
                (!to tier=p.parent anchor) |-(.child anchor)\forestoption{edge label};
            },
        }
    }{},
}

同样这也有效

\begin{forest}
m/.style={fill=color1!30},
f/.style={fill=color1!60,text=white},
h/.style={fill=color2!30},
  for tree={
    child anchor=west,
    parent anchor=east,
    grow'=east,%
  %minimum size=1cm,%new possibility  (note how did \\
  text width=4cm,%
    draw,
    anchor=west,
    edge path={
      \noexpand\path[\forestoption{edge}]
        (.child anchor) -| +(-5pt,0) -- +(-5pt,0) |-
        (!u.parent anchor)\forestoption{edge label};
    },
  }

注释掉\tikzset 并使用本地设置获得的错误消息告诉您问题：

! Package pgfkeys Error: I do not know the key '/tikz/belowab' and I am going 
to ignore it. Perhaps you misspelled it.

密钥处理器需要以下形式的密钥/tikz/...，因此您需要将/tikz密钥的本地路径设置为：

\documentclass{article}
\usepackage{forest}

\begin{document}

\begin{forest} 
/tikz/aboveab/.style={midway,  above,  font=\scriptsize,  text width=1.5cm,  align=center},
/tikz/belowab/.style={midway,  below,  font=\scriptsize,  text width=1.5cm,  align=center},
for tree={
  grow=east,
  draw=blue,
  circle,
  line width=0.2pt,
  parent anchor=east,
  child anchor=west,
  edge={draw=blue},
  edge label={\Huge\color{black}},
  edge path={
    \noexpand\path[\forestoption{edge}]
      (!u.parent anchor) -- ([xshift=-1.6cm].child anchor) --    
      (.child anchor)\forestoption{edge label};
  },
  l sep=2cm,
} 
[,rectangle, s sep=35pt,
  [,edge label={node[belowab]{Text}}
    [,edge label={node[belowab]{Text}}
    ]
    [,edge label={node[aboveab]{Text}}
    ]
  ]
  [,edge label={node[aboveab]{Text}}
    [,edge label={node[belowab]{Text}}
    ]
    [,edge label={node[aboveab]{text}}
    ]
  ]
]
\end{forest}

\end{document}

以下解释由萨索·日瓦诺维奇（软件包作者）comment：

当在节点规范中（即在内容之后）forest遇到未知键（在路径中）时，它会自动将键附加到键列表节点选项中，该选项在创建节点时传递给 tikz（然后路径自动更改为）。创建边标签时，您将直接在 tikz 中创建节点：请注意，使用的是 tikz 语法，节点选项放在方括号中。因此，必须在路径中创建此类样式。/forest/tikzedge label={node[aboveab]{Text}}/tikz
