强制GraphViz强制节点之间的距离

Question

我使用GraphViz和以下点文件:

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];
    }
}

它给我这样的东西:

但是我想要这样的东西:

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

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

我怎样才能做到这一点？

为了您的帮助,谢谢你提前.

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";整个子图的影响我必须在两个不同的子图中分割注释.

结果是:
