vertical-alignment - Force GraphViz 强制节点之间的距离

Question

我将 GraphViz 与以下点文件一起使用:

digraph G
{
    rankdir=LR;
    subgraph commits
    {
        "5c071a6b2c" -> "968bda3251" -> "9754d40473" -> "9e59700d33" -> "2a3242efa4";
    }
    subgraph annotations
    {
        "V1.0" [shape=box];
        "br/HEAD" [shape=box];
        "V1.0" -> "9e59700d33" [weight=0];
        "br/HEAD" -> "2a3242efa4" [weight=0];
    }
}

它给了我类似的东西:

但我想要这样的东西:

                                        V1.0         br/HEAD
                                          |             |
                                         \/            \/

5c071a6b2c -> 968bda3251 -> 9754d40473 -> 9e59700d33 -> 2a3242efa4

我该怎么做？

为了您的帮助，提前致谢。

Answer 1

这将使注释与提交对齐:

digraph G
{
    rankdir=LR;
    subgraph commits
    {
        "5c071a6b2c" -> "968bda3251" -> "9754d40473" -> "9e59700d33" -> "2a3242efa4";
    }
    subgraph annotations1
    {
        rank="same";
        "V1.0" [shape=box];
        "V1.0" -> "9e59700d33" [weight=0];
    }
    subgraph annotations2
    {
        rank="same";
        "br/HEAD" [shape=box];
        "br/HEAD" -> "2a3242efa4" [weight=0];
    }
}

由于 rank="same"; 影响整个子图，我不得不将注释拆分为两个不同的子图。

结果是:
