包装森林：将所有叶子对齐到同一级别，从根到叶子的路径着色

包装森林：将所有叶子对齐到同一级别，从根到叶子的路径着色

我有一棵茂密的树。我用森林包画了它。代码如下。它可能效率低下，但我希望以尽可能少的代码中断继续前进。我的问题是：
1.树是不对称的。所以，默认对齐是按级别进行的。如何将所有叶子对齐在同一级别？
2.如何使某些节点变成正方形，而其他节点保持圆形？
3.如何从根到特定叶子为路径着色不同的颜色？
4.我使用 \resizebox 使树适合页面。假设看到树的人将页面转为横向模式，是否有一个全局选项可以设置将所有节点文本垂直转动？

欢迎提出有关如何最好地展示这棵树的任何其他建议/想法。

答案1

更新代码无需修改即可与新版本 (2) 一起使用森林。

  1. 树是不对称的。因此，默认对齐方式是按级别对齐。如何将所有叶子对齐在同一级别？

tier=<tier name>这可以通过设置所有终端节点来实现。要自动执行此操作，请将此代码添加到for tree：

if n children=0{
  tier=terminal
}{}
  1. 如何使某些节点变成正方形，而其他节点保持为圆形？

您可以添加shape=rectangle那些您想要的非圆形。如果您想强制它们成为正方形，您可以输入它们的宽度和高度，但这可能会产生奇怪的结果。或者您想要成为正方形的和您想要成为圆形的是否有规律？

  1. 如何将一条从根到特定叶子的路径涂成不同的颜色？

您可以使用node walk它来追溯从叶子到根的路径。例如，这里有一个样式，它接受一个参数（颜色），并用该颜色为回到根的路径着色：

\forestset{
  colour my roots/.style={
    before typesetting nodes={
      edge=#1,
      for ancestors={
        edge=#1,
        #1,
      },
      #1,
    }
  }
}

要使用它，只需添加colour my roots=<colour>到您选择的节点即可。（不必是叶子 - 它将从其所在的位置开始。请注意，如果您多次使用此样式，则根节点将以最后使用的颜色结束，任何常见路径段也是如此。

这是一个简单的例子：

根部着色

\documentclass[tikz, border=10pt, multi]{standalone}
\usepackage{forest}
\forestset{
  colour my roots/.style={
    before typesetting nodes={
      edge=#1,
      for ancestors={
        edge=#1,
        #1,
      },
      #1,
    }
  },
  my edge label/.style={
    edge label={
      node [midway, fill=white, font=\scriptsize] {#1}
    }
  }
}
\begin{document}
\begin{forest}
  for tree={
    circle,
    inner sep=1pt,
    l sep+=5pt,
    draw,
    align=center,
    if n children=0{
      tier=terminal
    }{},
  }
  [HP
    [IP, my edge label=NB
      [ABC
        [DEF]
        [GEH, colour my roots=blue]
      ]
      [HIJ
        [LMN, colour my roots=red
          [OPQ]
        ]
        [RST]
      ]
    ]
  ]
\end{forest}
\end{document}

以下是示例结果：

茂密的树

  1. 我使用 \resizebox 来让树适合页面。假设看到树的人将页面转为横向模式，是否有一个全局选项可以让我设置将所有节点文本垂直转？

不要。这会让事情变得不必要地复杂化。相反，用默认的生长方向绘制树并将其放在环境中landscape。（或者，sidewaysfigure如果您不想翻页，请使用。

这对代码的改动很小。但请注意，你可以让生活简单得多如果您使用几种样式而不是经常重复代码，那就为自己吧。

事实上，只需添加font=\tiny就可以节省每个节点内容的for tree书写。\tiny{}

如果您也能管理样式，标签可以大大简化。如果标签或内容有模式，您可以进一步自动化树。如果没有，您将得到如下结果：

\documentclass[a5paper]{article}
\usepackage[margin=0.5in]{geometry}
\usepackage[T1]{fontenc}
\usepackage{forest,pdflscape}
\forestset{
  colour my roots/.style={
    before typesetting nodes={
      edge=#1,
      for ancestors={
        edge=#1,
        #1,
      },
      #1,
    }
  },
  my edge label/.style={
    edge label={
      node [midway, fill=white, font=\scriptsize] {#1}
    }
  }
}
\begin{document}
\newlength\myheight
\setlength\myheight{\textheight}%
  \begin{landscape}
    \noindent
  \resizebox{\myheight}{!}{%
  \begin{forest} %Figure out how to align edge labels with the edge
    for tree={
      circle,
      draw,
      align=center,
      if n children=0{
        tier=terminal
      }{},
      font=\tiny
    }
  [HP
      [IP, my edge label=NB  %not built

...

      ]
  ]
  \end{forest}%
}%
\end{landscape}
\end{document}

它仍然没有那么混乱，而且肯定也没有那么重复的打字！

最后，如果你的实际树与此类似，你需要重新考虑呈现这些信息的方式。

此刻没人能阅读任何东西。即使人们只阅读电子书籍，并可以快速浏览（但既然如此，何必拘泥于一小页呢？真正大尺寸的电子纸仍然很便宜！），也根本不会明显看出有什么值得快速浏览的东西。

最好的情况是，你会激怒你的读者。最坏的情况是，他们会沮丧地放弃。

答案2

  1. 添加到序言：（where n children=0{tier=bottom}{}不要忘记前面的逗号！）

  2. rectangle向这些节点添加选项

  3. 在那片叶子上，添加for ancestors={edge=red}

  4. 使用tikz的键rotate来旋转节点。 在您的例子中，将其添加for tree={rotate=90}到前导码，以及rotate=90所有边缘标签节点。

我实际上建议定义一种样式来指定边缘标签。将其放在你的序言中：

my edge label/.style={edge label={node[midway,fill=white,font=\scriptsize]{#1}}},

my edge label=NB然后通过书写等来指定边标签。
