TikZ Tree：更改特定樹邊緣的樣式

Question

我想改變樹的某些邊緣的樣式。我想要一條從樹根到一片葉子的紅色虛線路徑。但是如果我改變一些特定的邊緣，下面的所有邊緣也會改變。連標籤也變紅了，這是我不想要的。

這就是發生的事情：

但我想要這樣的東西：

有什麼建議麼？這不可能那麼難。但我花了一個多小時試圖找出答案。這是我的程式碼：

\documentclass[border=10pt,svgnames]{standalone} 

\usepackage{tikz}
\usetikzlibrary{positioning,automata,backgrounds}
\definecolor{light-gray}{gray}{0.6}


\begin{document}
\centering
\begin{tikzpicture}[level distance=1.5cm,
  level 1/.style={sibling distance=3cm},
  level 2/.style={sibling distance=1cm},
  level 3/.style={sibling distance=1cm},
  every node/.style={thin}]
  \node {1}
    child {node {00}
      child {node {00}}
      child {node {}}
      child {node {10}}
      child {node {}}
    }
    child {node {}}
    child {node {10}
    child {node {00} edge from parent[dashed, very thick, red]
    child {node {00}}  
    child {node {01}}
    child {node {10}}
    child {node {11} edge from parent[dashed, very thick, red]}
    }
    child {node {}}
    child {node {}}
    child {node {11}}
    }
    child {node {}};
\end{tikzpicture}
\end{document}

Answer 1

您可以使用Forest使用簡單的語法來自訂樹的每個邊緣，只需插入像這樣的邊緣選項

edge={dashed,red,thick}

完整程式碼

\documentclass[border=10pt,svgnames]{standalone} 
\usepackage{forest}

\begin{document}

\begin{forest}
for tree={delay={where content={}{content={\phantom{00}}}{}},s sep+=5mm,l+=5mm}
[1
  [00
     [00]
     []
     [10]
     []  
  ]
  []
  [10,edge={dashed,red,thick} 
     [00,edge={dashed,red,thick}
        [00]
        [01]
        [10]
        [11,edge={dashed,red,thick}]     
     ]
     []
     []
     [11]  
  ]
  [\phantom{00}]
]
\end{forest}

\end{document}
