Tikz 层次结构图 - 分支子级

Question

\documentclass{article}
\usepackage{tikz-qtree}

\begin{document}
\tikzset{edge from parent/.style=
{draw, edge from parent path={(\tikzparentnode.south)
-- +(0,-8pt)
-| (\tikzchildnode)}},
blank/.style={draw=none},
level distance=45pt}
\begin{tikzpicture}[every tree node/.style={align=center,minimum width=\widthof{Janet Botwood}}]
 \Tree 
[ .{Ruth Butler\\Registered Manager} 
[ .{Anita Kaur\\Registered Manager} ] 
 [ .{Janet Botwood\\Head of Care} ] 
 [ .{Sunny Bell\\Head of Care}  ] ] 
\end{tikzpicture}

\end{document}

我试图让 Anita 和 Ruth 处于同一分支级别。另外，我该如何创建 Janet 和 Sunny 的子分支？

Answer 1

树不适用于多个“父母”。我不确定，如果我理解得对，但您可以将两个名字放入一个节点中：

% arara: pdflatex

\documentclass{article}
\usepackage{tikz-qtree}
\usetikzlibrary{shapes}

\begin{document}
    \tikzset{edge from parent/.style=
        {draw, edge from parent path={(\tikzparentnode.south)
                -- +(0,-8pt)
                -| (\tikzchildnode)}},
        blank/.style={draw=none},
        level distance=45pt}
    \begin{tikzpicture}[every tree node/.style={align=center,minimum width=\widthof{Janet Botwood}}]
    \Tree [.\node(grands)[rectangle split,rectangle split horizontal,rectangle split parts=2]{Ruth Butler\\Registered Manager \nodepart{second} Anita Kaur\\Registered Manager};  
    [ .{Janet Botwood\\Head of Care} A B C  ] 
    [ .{Sunny Bell\\Head of Care} D E F ] ] 
\end{tikzpicture}
\end{document}

Answer 2

像这样吗？

这使用了 powerforest包。让 Ruth 和 Anita 处于同一级别的技巧是让她们成为某个phantom节点的子节点，因为树必须有一个根。

\documentclass[tikz,border=5pt,multi]{standalone}
\usepackage{forest}
\begin{document}
\begin{forest}
  for tree={
    edge path={
      \noexpand\path [draw, \forestoption{edge}] (!u.parent anchor) -- +(0,-5pt) -| (.child anchor)\forestoption{edge label};
    },
    align=center,
    parent anchor=south,
    child anchor=north
  }
  [, phantom, for children={fit=band}
    [Ruth Butler\\Registered Manager
      [Janet Botwood\\Head of Care
        [child 1]
        [child 2]
        [child 3]
      ]
      [Sunny Bell\\Head of Care
        [child 1]
        [child 2]
        [child 3]
      ]
    ]
    [Anita Kaur\\Registered Manager]
  ]
\end{forest}
\end{document}

或者像这样？

\documentclass[tikz,border=5pt,multi]{standalone}
\usepackage{forest}
\begin{document}
\begin{forest}
  for tree={
    edge path={
      \noexpand\path [draw, \forestoption{edge}] (!u.parent anchor) -- +(0,-5pt) -| (.child anchor)\forestoption{edge label};
    },
    align=center,
    parent anchor=south,
    child anchor=north
  }
  [, phantom, for children={fit=band}
    [Ruth Butler\\Registered Manager
      [Janet Botwood\\Head of Care
        [child 1]
        [child 2]
        [child 3]
      ]
    ]
    [Anita Kaur\\Registered Manager
      [Sunny Bell\\Head of Care
        [child 1]
        [child 2]
        [child 3]
      ]
    ]
  ]
\end{forest}
\end{document}
