从西向东到南向重排 TikZ 森林

Question

我有以下 TikZ 森林：

\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows,positioning,automata,fit}
\usepackage{forest}
\tikzset{
    >=stealth,
    auto,
    thick,
    node distance=2.5cm,
    transform shape,
}

\begin{document}
\begin{forest}
for tree={
    child anchor=west,
    parent anchor=east,
    grow=east,
    draw,
    thick,
    rounded corners=1mm,
    anchor=west,
    edge path={
    \noexpand\path[\forestoption{edge}]
        (.child anchor) -| +(-5pt,0) -- +(-5pt,0) |-
        (!u.parent anchor)\forestoption{edge label};
    },
}
[Bill
    [Bob
        [Rich
            [Sam]
            [Susan]
        ]
        [Patty]
    ]
    [Mary
        [Mike]
        [Kathy]
    ]
]
\end{forest}
\end{document}

生成图像：

这棵树从西向东“流动”。我一直在尝试锚点设置，看看能否让它从北向南生长，最低节点是 Bill 标记的节点（就像标准的家谱一样），但我似乎无法让边缘看起来正确且不重叠。

有什么建议么？

Answer 1

评论太长了。你的树的“流程”由键控制grow=east，但你似乎想要grow=south。然后你需要调整父母和孩子的锚点，正如你所预料的那样。请注意，你的\tikzset{...}东西没有效果，所以我放弃了它。

\documentclass[tikz]{standalone}
\usepackage{forest}
\begin{document}
\begin{forest}
for tree={parent anchor=south,child anchor=north,
    draw,
    thick,
    rounded corners=1mm,
    edge path={
    \noexpand\path[\forestoption{edge}]
        (!u.parent anchor) --  +(0,-5pt) -|
        (.child anchor)\forestoption{edge label};
    },
}
[Bill
    [Bob
        [Rich
            [Sam]
            [Susan]
        ]
        [Patty]
    ]
    [Mary
        [Mike]
        [Kathy]
    ]
]
\end{forest}
\end{document}

获得（几乎）相同结果的一种可能更简单的方法是仅使用，如果您加载库，即，则forked edges​​可用。edges\usepackage[edges]{forest}

\documentclass[tikz]{standalone}
\usepackage[edges]{forest}
\begin{document}
\begin{forest}
forked edges,
for tree={grow=south,
    draw,
    thick,
    rounded corners=1mm,
}
[Bill
    [Bob
        [Rich
            [Sam]
            [Susan]
        ]
        [Patty]
    ]
    [Mary
        [Mike]
        [Kathy]
    ]
]
\end{forest}
\end{document}
