Tikz：循环树中的“倾斜”问题

我正在尝试在树的边缘获取倾斜的文本。

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{trees}
\usetikzlibrary{graphs}
\usetikzlibrary{positioning}
\renewcommand{\baselinestretch}{1.3}
\begin{document}

    \begin{tikzpicture}[
    sloped,
    minimum size=6mm,
    align=flush center,
    concept/.style={
        draw=#1!80!black,
        very thick,
        fill=#1!25,
        rounded corners
    },
    concept/.default=white,
    description/.style={
        font=\footnotesize,
        draw,
        dashed
    },
]
\node [concept=black] {EQUITY\\MARKETS} [
    grow cyclic,
    sibling angle=120,
    level distance=5em
]
child {
    child {
        node [concept={red}] {Private} [sibling angle=90]
        child {node [description]   {Not listed on\\Stock Exchange} }
        child {
            node [concept={orange}] {Private\\Equity Fund}
            child{ node [description={above}] {Organization} }
            child { [level distance=3em, sibling angle=60]
                child{ [sibling angle=60, level distance=5em]
                    child {node {Venture\\Capital} }
                    child {node {Growth\\Capital} }
                    child {node {Leverage\\Buyout} }
                }
                edge from parent
                node [midway, sloped] {Strategies} 
            }
        }
    }
    child {
        node [concept={blue}] {Public}
        child {node [description] {Listed on\\Stock Exchange} }
    }
    edge from parent
    node [midway,sloped] {Types} 
}
child { node[description={right}] {Ownership\\of Entity} }
;
\end{tikzpicture}
\end{document}

我希望“类型”和“策略”能够倾斜在边缘上。

我曾尝试使用倾斜选项，但并没有改变任何东西。

如果有必要的话，我正在使用 Overleaf。

如果有其他方法可以改进代码，我将非常感激您的建议。我现在才刚刚开始，对 Ti 还不是很擅长钾Z。 这是我的输出

好问题！你怀疑这是由什么引发的，grow cyclic这一点很正确。问题是grow cyclic安装了自己的转换。因此这些节点是倾斜，但相对于旋转的坐标系，所以它们最终不是倾斜的。这可以从以下线条中看出

\tikzset{grow cyclic/.style={growth function=\tikz@grow@circle}}%

和

\def\tikz@grow@circle{%
  \pgftransformrotate{%
    (\pgfkeysvalueof{/tikz/sibling angle})*(-.5-.5*\tikznumberofchildren+\tikznumberofcurrentchild)}%
  \pgftransformxshift{\the\tikzleveldistance}%
}%

tikzlibrarytrees.code.tex避免这种情况的一种方法是

  1. 定义你自己edge from parent macro的
  2. 您本地重置了这些转换。

代码和结果：

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{trees,scopes}
\begin{document}
    \begin{tikzpicture}[
    minimum size=6mm,
    align=flush center,
    concept/.style={
        draw=#1!80!black,
        very thick,
        fill=#1!25,
        rounded corners
    },
    concept/.default=white,
    description/.style={
        font=\footnotesize,
        draw,
        dashed
    },
    edge from parent macro=\mymacro
]
\def\mymacro#1#2{[style=edge from parent, #1]
{[/utils/exec=\pgftransformreset](\tikzparentnode\tikzparentanchor) -- #2
(\tikzchildnode\tikzchildanchor)} }
\node [concept=black] {EQUITY\\MARKETS} [
    grow cyclic,
    sibling angle=120,
    level distance=5em
]
child {
    child {
        node [concept={red}] {Private} [sibling angle=90]
        child {node [description]   {Not listed on\\Stock Exchange} }
        child {
            node [concept={orange}] {Private\\Equity Fund}
            child{ node [description={above}] {Organization} }
            child { [level distance=3em, sibling angle=60]
                child{ [sibling angle=60, level distance=5em]
                    child {node {Venture\\Capital} }
                    child {node {Growth\\Capital} }
                    child {node {Leverage\\Buyout} }
                }
                edge from parent
                node [pos=1.2,sloped,above] {Strategies} 
            }
        }
    }
    child {
        node [concept={blue}] {Public}
        child {node [description] {Listed on\\Stock Exchange} }
    }
    edge from parent
    node [pos=0.6,sloped,above] {Types} 
}
child { node[description={right}] {Ownership\\of Entity} };
\end{tikzpicture}
\end{document}

在此处输入图片描述

更新：Henri Menke 与我分享了一种更简单、更优雅的方法来实现这一点。只需添加edge from parent/.append style={reset cm}。全部功劳归于 Henri Menke。

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{trees}
\begin{document}
    \begin{tikzpicture}[
    minimum size=6mm,
    align=flush center,
    concept/.style={
        draw=#1!80!black,
        very thick,
        fill=#1!25,
        rounded corners
    },
    concept/.default=white,
    description/.style={
        font=\footnotesize,
        draw,
        dashed
    },
    edge from parent/.append style={reset cm}
]
\node [concept=black] {EQUITY\\MARKETS} [
    grow cyclic,
    sibling angle=120,
    level distance=5em
]
child {
    child {
        node [concept={red}] {Private} [sibling angle=90]
        child {node [description]   {Not listed on\\Stock Exchange} }
        child {
            node [concept={orange}] {Private\\Equity Fund}
            child{ node [description={above}] {Organization} }
            child { [level distance=3em, sibling angle=60]
                child{ [sibling angle=60, level distance=5em]
                    child {node {Venture\\Capital} }
                    child {node {Growth\\Capital} }
                    child {node {Leverage\\Buyout} }
                }
                edge from parent
                node [pos=1.2,sloped,above] {Strategies} 
            }
        }
    }
    child {
        node [concept={blue}] {Public}
        child {node [description] {Listed on\\Stock Exchange} }
    }
    edge from parent
    node [pos=0.6,sloped,above] {Types} 
}
child { node[description={right}] {Ownership\\of Entity} };
\end{tikzpicture}
\end{document}

这会导致同样的结果，grow cyclic使用

 \tikzset{grow cyclic/.append style={edge from parent/.append style={reset cm}}}
