Question

这个答案与 Qrrbrbbirbel 对节点文本旋转所做的类似。但我没有旋转节点文本，而是修改了路径，edge from parent以便挤入更多信息。

需要旋转的节点需要密钥mind your rotate。

首先是代码和结果，

\documentclass[tikz]{standalone}
\usetikzlibrary{mindmap}
\def\myrotangle{0}
\makeatletter
\tikzset{tikz@concept@setting/.style={edge from parent path={
        (\tikzparentnode) 
        \pgfextra{
        \pgfpointdiff{%}
            \pgfpointanchor{\tikzchildnode}{north}
        }
        {%}
            \pgfpointanchor{\tikzchildnode}{south}
        }
        \pgfmathsetmacro\mychildsize{veclen(\pgf@x,\pgf@y)}
        \pgfpathmoveto{\pgfpointanchor{\tikzchildnode}{center}}
        \pgfset{minimum size=\mychildsize}
        \pgfsetlinewidth{1mm}
        \pgfnode{circle}{center}{}{\tikzchildnode-temp}{\pgfusepath{discard}}
             \pgfpointdiff{%}
                 \pgfpointanchor{\tikzchildnode}{center}
                }
                {%}
                 \pgfpointanchor{\tikzparentnode}{center}
                }
            \pgfmathparse{atan2(\pgf@x,\pgf@y)}%
            \xdef\myrotangle{\pgfmathresult}
            \pgfmathparse{((\myrotangle>90+\pgfkeysvalueof{/tikz/sibling angle})&&(\myrotangle<270+\pgfkeysvalueof{/tikz/sibling angle})?(\myrotangle + 180):(\myrotangle))}
            \xdef\myrotangle{\pgfmathresult}
            }
        to [circle connection bar] (\tikzchildnode-temp)
        }
    }
}

\makeatother


\tikzset{mind your rotate/.style={
    rotate=\myrotangle-\pgfkeysvalueof{/tikz/sibling angle}
    }
}

在此处输入图片描述

简而言之，发生的事情是：常规父子节点名称被捕获。使用它们的坐标计算旋转角度。还测量了子节点的大小（粗略地！）。然后将临时的非旋转节点放置在子节点之上，这样连接栏就不会混淆。

还有几点我遗漏了；

子节点的尺寸测量相当原始。没有考虑线宽、内部分隔，但我认为手动测量可以实现更平滑的连接。（测量值以黄线显示）
旋转校正代码是直接复制/粘贴完成的，因此可能需要再次检查。我觉得我遗漏了一些东西，但没有进行广泛的测试。
总的来说，我认为这不能与其他节点形状一起使用，因为对于连接转换来说，想出的代码真的很难。
