如何防止子图簇对齐顺序被颠倒?

How to prevent the subgraph cluster alignment order from being reversed?

如果我有这样的 graphviz dot 脚本:

digraph g {
node [style=rounded, shape=box]

    subgraph cluster1 {
        style="invis"
        1 -> 2 -> 3 -> 4 -> 5
    }

    subgraph cluster2 {
        style="invis"
         6 -> 7

         7 -> 8 -> 11
         7 -> 9 -> 11
         7 -> 10 -> 11
    }

    edge[constraint=false];
    splines="ortho"
    5 -> 6 [weight=0]
}

我得到如下所示的输出(我想要的):

但是,如果末尾的某些节点中的标签变得太长,则排列会反转如下:

digraph g {
node [style=rounded, shape=box]

8 [label="very long label"]
9 [label="very long label"]
10 [label="very long label"]


    subgraph cluster1 {
        style="invis"
        1 -> 2 -> 3 -> 4 -> 5
    }

    subgraph cluster2 {
        style="invis"
         6 -> 7

         7 -> 8 -> 11
         7 -> 9 -> 11
         7 -> 10 -> 11
    }

    edge[constraint=false];
    splines="ortho"
    5 -> 6 [weight=0]
}

如何防止这种情况发生并强制使用原始订购方法?

您必须先定义另一个长标签,然后再定义您的长标签; graphviz 按照定义的顺序绘制节点。

digraph g {
node [style=rounded, shape=box]

    subgraph cluster1 {
        style="invis"
        1 -> 2 -> 3 -> 4 -> 5
    }

    subgraph cluster2 {
        style="invis"
         6 -> 7

         7 -> 8 -> 11
         7 -> 9 -> 11
         7 -> 10 -> 11
    }

    8 [label="very long label"]
    9 [label="very long label"]
    10 [label="very long label"]

    edge[constraint=false];
    splines="ortho"
    5 -> 6 [weight=0]
}
