力GraphViz力在子图之间对齐

Question

我在以下点文件中使用GraphViz：

digraph "Fast-forward"
{
    rankdir=LR;
    subgraph master
    {
        "5c071a6b2c" -> "968bda3251";
    }
    subgraph branch
    {
        "35ee8ce6b6" [color="blue"] [style="filled"];
        "968bda3251" -> "9754d40473" [weight=0];
        "9754d40473" -> "9e59700d33" -> "35ee8ce6b6";
    }
    subgraph c1
    {
        rankdir=LR;
        rank="same";
        "remote/master/HEAD" [shape=box];
        "remote/master/HEAD" -> "35ee8ce6b6" [weight=0];
        oldmh [label="master/HEAD"] [shape=box] [color="red"] [style="filled"];
        newmh [label="master/HEAD"] [shape=box] [color="blue"] [style="filled"];
        oldmh -> "968bda3251" [weight=0];
        newmh -> "35ee8ce6b6" [weight=0];
    }
}

它给了我这样的东西：

​

但我想要这样的东西：

white | \/ "9754d40473" -> "9e59700d33" -> "35ee8ce6b6"; / /\ 5c071a6b2c -> 968 3251/\ _

我怎么能这么做？

谢谢你的帮助，提前谢了。

Answer 1

我倾向于首先定义所有具有特殊需求的节点(比如处于同一级别或具有特殊形状/颜色)，然后定义链接。这样，您就可以确保正确地分组rank=same节点，并按照正确的顺序进行定义。

没有weight=0，所有的侧链接都会在顶部结束。将weight=0添加到您想要的底部。

digraph "Fast-forward"
{
    rankdir=LR;
    subgraph c1 {
        rank="same";
        "968bda3251";
        oldmh [label="master/HEAD"] [shape=box] [color="red"] [style="filled"];
    }
    subgraph c2
    {
        rank="same";
        "remote/master/HEAD" [shape=box];
        "35ee8ce6b6" [color="blue"] [style="filled"];
        newmh [label="master/HEAD"] [shape=box] [color="blue"] [style="filled"];
    }
    "5c071a6b2c" -> "968bda3251" -> "9754d40473" -> "9e59700d33" -> "35ee8ce6b6";
    oldmh -> "968bda3251" [weight=0];
    "remote/master/HEAD" -> "35ee8ce6b6";
    newmh -> "35ee8ce6b6" [weight=0];
}

如果你真的想在96到97之间慢跑，你可以这样做：

digraph "Fast-forward"
{
    rankdir=LR;
    subgraph c1 {
        rank=same;
        "968bda3251";
        oldmh [label="master/HEAD"] [shape=box] [color="red"] [style="filled"];
    }
    subgraph c1p5 {
        rank=same;
        "9754d40473";
        inviso [style="invis"];
    }
    subgraph c2
    {
        rank="same";
        "remote/master/HEAD" [shape=box];
        "35ee8ce6b6" [color="blue"] [style="filled"];
        newmh [label="master/HEAD"] [shape=box] [color="blue"] [style="filled"];
    }
    "5c071a6b2c" -> "968bda3251";
    "968bda3251" -> "9754d40473" [weight=0];
    "9754d40473" -> "9e59700d33" -> "35ee8ce6b6";
    oldmh -> "968bda3251" [weight=0];
    "remote/master/HEAD" -> "35ee8ce6b6";
    newmh -> "35ee8ce6b6" [weight=0];
    "968bda3251" -> inviso [style="invis"];
    "9754d40473" -> inviso [style="invis"];
}

Answer 2

rank="same"会影响子图的所有节点，因此必须将标记子图分成两部分：

digraph "Fast-forward"
{
    rankdir=LR;
    subgraph master
    {
        "5c071a6b2c" -> "968bda3251";
    }
    subgraph branch
    {
        "968bda3251" -> "9754d40473" [weight=0];
        "9754d40473" -> "9e59700d33" -> "35ee8ce6b6";
        "35ee8ce6b6" [color="blue"] [style="filled"];
    }
    subgraph c1
    {
        rank="same";
        "remote/master/HEAD" [shape=box];
        "remote/master/HEAD" -> "35ee8ce6b6" [weight=0];
        newmh [label="master/HEAD"] [shape=box] [color="blue"] [style="filled"];
        newmh -> "35ee8ce6b6" [weight=0];
    }
    subgraph c2
    {
        rank="same";
        oldmh [label="master/HEAD"] [shape=box] [color="red"] [style="filled"];
        oldmh -> "968bda3251" [weight=0];
    }
}

这将给你：
