手动

我根据这个例子创建了一个思维导图：http://www.texample.net/tikz/examples/computer-science-mindmap/

有时分支包含的信息太多，导致地图看起来很丑陋，如下例所示：

在此处输入图片描述

这是我使用的代码：

\documentclass[landscape]{article}

\usepackage{tikz}
\usetikzlibrary{mindmap,trees}
\begin{document}
\pagestyle{empty}
\begin{tikzpicture}
  \path[mindmap,concept color=black,text=white]
    node[concept] {Main Topic}
    [clockwise from=0]
    child[concept color=green!50!black] {
      node[concept] {definition}
      child { node[concept] {this is a very long sentence ... very long sentence ... and it is even longer ...} }
      child { node[concept] {this is a very long sentence ... very long sentence ... and it is even longer ...} }
    }  
    child[concept color=blue] { node[concept] {Subtopic 1} }
    child[concept color=red] { node[concept] {Subtopic 2} }
    child[concept color=orange] { node[concept] {Subtopic 3} }
    child[concept color=purple] { node[concept] {Subtopic 4} }
    child[concept color=brown] { node[concept] {Subtopic 5} };
\end{tikzpicture}
\end{document}

是否有可能创建不显示为圆圈而是仅显示为线的分支，就像本例中那样，根本不使用图片？

手动

一种相当手动的方式是使用“定义”来命名节点，例如(def)，并使用位于右侧的普通节点def。

我为这些所谓的“非概念”创建了一种风格：

  • rectangle（默认），
  • text width=12em，
  • execute at begin node=\footnotesize而不是font=\footnotesize（不能完美地与结合text width。

此外，我为从到那些非概念的cncc east路径创建了一种风格。 它包括def

  • out=0和in=180，和

  • A to path。

    to由于声明中的使用to path失败，我回到了较低的版本\tikz@to@curve@path，它计算来自的路径

    • tikztostart和
    • tikztotarget

    .east它们先前分别设置为和.south west锚点。

    另外，.south east目标节点的角用于确定线以下节点。

代码

\tikzset{
    non-concept/.style={
        rectangle,

                      % where the non-concept is east of the concept

        in=180,

（有点）自动

我更喜欢上面描述的手动方式。

设置edge of parent path不是一个大问题，甚至更容易。

但是在正确的级别分配正确的样式非常烦人，而且必须编写自定义的growth function。

代码

\documentclass[tikz, border=2pt]{standalone}
\usetikzlibrary{mindmap,trees,positioning}
\makeatletter
\tikzset{
    non-concept/.style={
        rectangle,
        text width=12em,
        text=black,
        align=left,
    },
    cncc east/.style={
        edge from parent path={
            (\tikzparentnode.east) to[out=0, in=180] (\tikzchildnode.south west)
            -- (\tikzchildnode.south east)
        }
    }
}
\makeatother
\begin{document}
\pagestyle{empty}
\begin{tikzpicture}
  \path[mindmap, concept color=black, text=white]
    node[concept] {Main Topic}[clockwise from=0]% named \___/ node
    child[concept color=green!50!black] {
        node[concept] (def) {definition}
        [
            grow=right,
            sibling distance=14ex,
        ]
            child[level distance=5cm] { node[non-concept] {What does each person know and not know about my topic?}                            edge from parent[cncc east] }
            child[level distance=5cm] { node[non-concept] {How will each person react? What concerns will I need to overcome?}                 edge from parent[cncc east] }
            child[level distance=5cm] { node[non-concept] {Who exactly is my audience? What is each listener's role and reason for attending?} edge from parent[cncc east] }
        }
    child[concept color=blue]           { node[concept]       {Subtopic 1} }
    child[concept color=red]            { node[concept]       {Subtopic 2} }
    child[concept color=orange]         { node[concept]       {Subtopic 3} }
    child[concept color=purple]         { node[concept]       {Subtopic 4} }
