减少森林树木宽度但不挤压树木

Question

如果这是一个愚蠢的问题，请原谅 - 这是我在 stackexchange 上的第一个问题。我使用 forest 包构建了下面的树。不幸的是，这棵树对于页面来说太“宽”了。

有没有办法让森林将粉色框放在绿色框下方的长线上，以便树适合页面？或者你能想出一种方法来排版此图，使其水平适合而不会看起来太“挤压”吗？

谢谢！

您可以调整text width节点，也可以调整lanss sep以使节点更接近。进一步添加，交换 Sub distributor节点。不过，您必须稍微修改虚线箭头。

}

\begin{document}

\begin{forest}
for tree={%
    l sep=1cm,
    s sep=0.1cm,
    minimum height=0.8cm,

                [Customer] {\draw[->,dotted] () -- ++(-4cm,0) to[out=north,in=west] (Company);}
                [Installer]
                [Installer]
            ]
            [Agent]

我希望这足以将内容带入页面；-)。

通过s=1cm使用

[Company,s=1cm, name=Company,... 

可以调整绿色和粉色团伙之间的水平间距，以获得

但它又会增加总宽度（这正是我们试图减少的！）。

将粉色向左移动将得到

    [Distributor, for tree={child, fill=pink!50}

            [Installer

        [Sub distributor
            [Agent]
            [Agent]
        ]
        [Sub distributor,
            [Agent,
                [Customer] {\draw[->,dotted] () --++(0,-1cm) -- ++(6.5cm,0) to[out=north,in=east] (Company);}
                [Installer]
                [Installer]
            ]
            [Agent]

    ]
]

\end{document}

正如所见，情况并没有太大改善。
