当其他节点分叉时，如何使节点以不同的方式增长

Question

我是 Latex 的初学者，对探索其广泛的功能非常感兴趣。我想建立一个家谱，并决定使用 Forest 包。我使用这个手册 -森林_doc。

我开始构建一棵有分叉边的树。我从第 4.2 节了解到，分叉边命令会修改父锚点和子锚点并设置必要的边路径。但我想要一个具有不同父锚点并经过手动校正的子锚点。我弄清楚了手动校正部分。但锚点，我无法覆盖。

这是我的代码：

\documentclass[border=10pt]{standalone}

\usepackage[edges]{forest}
\usepackage{xcolor}

\begin{document}
    \begin{forest}
        man/.style = {fill=blue!70},
        woman/.style = {fill=green},
        for tree={draw={black, thick}, edge = {draw, thick}, rounded corners, inner sep=5pt},
        [Parent, man
            [Wife, woman, for tree={grow=0} , before drawing tree={x+=5.5cm, y+=1cm}]
            [Child, man, forked edges
                [Grand Child, man]
                [Grand Child, woman]
            ]
            [Child, woman, forked edges
                [Grand Child, man]
                [Grand Child, man]
            ]
        ]
    \end{forest}
\end{document}

结果如下：

我希望妻子节点的边缘从父母的东边开始，而不是从南边开始。请告诉我我应该给出什么选项。我尝试了父锚点和子锚点，但都没有用。提前谢谢！

Answer 1

我对 了解不多forest，所以我不知道是否可行。似乎forked edges将边缘锚点移动到一个点。一种可能性是先绘制no edge它，然后再绘制它，如下所示：

\documentclass[border=10pt]{standalone}    
\usepackage[edges]{forest}
\begin{document}
    \begin{forest}
        man/.style = {fill=blue!70},
        woman/.style = {fill=green},
        for tree={draw={black, thick}, edge = {draw, thick}, rounded corners, inner sep=5pt},
        [Parent, man,
            [Wife, woman, for tree={grow=0} , before drawing tree={x+=5.5cm, y+=1cm}, no edge] {\draw[thick] () -- (!u);}
            [Child, man, forked edges
                [Grand Child, man]
                [Grand Child, woman]
            ]
            [Child, woman, forked edges
                [Grand Child, man]
                [Grand Child, man]
            ]
        ]
    \end{forest}
\end{document}

编辑：

通过创建phantom根，您可以使Parent和Wife子级处于同一级别，从而自动对齐它们，如下所示：

\documentclass[border=10pt]{standalone}
\usepackage[edges]{forest}
\begin{document}
    \begin{forest}
        man/.style = {fill=blue!70},
        woman/.style = {fill=green},
        for tree={draw={black, thick}, edge = {draw, thick}, rounded corners, inner sep=5pt},
        [,phantom[Parent, man
            [Child, man, forked edges
                [Grand Child, man]
                [Grand Child, woman]
            ]
            [Child, woman, forked edges
                [Grand Child, man]
                [Grand Child, man]
            ]
        ] [Wife, woman, no edge] {\draw[thick] () -- (!p);}]
    \end{forest}
\end{document}

Answer 2

@hpekristiansen 第一个答案的细微变化：

\documentclass[border=3.141592]{standalone}
\usepackage[edges]{forest}

\begin{document}
    \begin{forest}
for tree={
% common nodes style
    draw,
    thick,
    rounded corners, 
% styles
  man/.style = {fill=cyan!30},
woman/.style = {fill=teal!30},
% tree
    forked edge,
    edge = {-, semithick},
        }
[Parent, man, name=P
    [Wife, woman, name=W, no edge,
for tree={grow=east, anchor=base},
before computing xy={l=-0mm,s=33mm},
    ]
    [Child, man, 
        [Grand Child, man]
        [Grand Child, woman]
    ]
    [Child, woman,
        [Grand Child, man]
        [Grand Child, man]
    ]
]
\draw[semithick] (P) -- (W);
    \end{forest}
\end{document}
