Graphviz 水平子图及其节点垂直对齐

我在水平组织子图和垂直组织子图中的节点时遇到问题。所有这些（子图和节点）仅在一条线上（水平或垂直）

---

我还尝试了

{rank=same；N1；N3；…；}

。这将从子图中删除节点

您可以使用类似的方法：

digraph G {
  rankdir = LR;
  subgraph cluster_0 {
    {rank=same N1 N2}
    label = "Title 1";
    N1 -> N2;
  }
  subgraph cluster_1 {
    {rank=same N3 N4 N5}
    label = "Title 2";
    N3 -> N4 -> N5;
  }
  subgraph cluster_2 {
    node [style=filled];
    label = "Title 3";
    N6;
  }

  N2 -> N3;
  N5 -> N6;
  N1 [label = "BA_A", fillcolor="green", shape="Msquare"]
  N2 [label = "W2", fillcolor="green", shape="octagon"]
  N3 [label = "BA_A", fillcolor="green", shape="Msquare"]
  N4 [label = "W2", fillcolor="green", shape="octagon"]
  N5 [label = "W2_ERROR", fillcolor="red", shape="octagon"]
  N6 [label = "W3", fillcolor="green", shape="invtriangle"]
}

在你的情况下，我更喜欢顶部而不是底部的布局

digraph G {
  rankdir = TB;
  node [style=filled];
  subgraph cluster_0 {
    N1 N2
    label = "Title 1";
    edge [dir = back]
    N2 -> N1;
  }
  subgraph cluster_1 {
    N3 N4 N5
    label = "Title 2";
    edge [dir = back]
    N5 -> N4 -> N3;
  }
  subgraph cluster_2 {
    label = "Title 3";
    N6
  }
  N2 -> N3 [constraint=none];
  N5 -> N6 [constraint=none];
  N1 [label = "BA_A", fillcolor="green", shape="Msquare"]
  N2 [label = "W2", fillcolor="green", shape="octagon"]
  N3 [label = "BA_A", fillcolor="green", shape="Msquare"]
  N4 [label = "W2", fillcolor="green", shape="octagon"]
  N5 [label = "W2_ERROR", fillcolor="red", shape="octagon"]
  N6 [label = "W3", fillcolor="green", shape="invtriangle"]
}

谢谢！你知道我怎样才能把所有的子图都放到最上面吗？子图之间的边将具有曲线连接，而不是直接连接

digraph G {
  rankdir = TB;
  node [style=filled];
  subgraph cluster_0 {
    N1 N2
    label = "Title 1";
    edge [dir = back]
    N2 -> N1;
  }
  subgraph cluster_1 {
    N3 N4 N5
    label = "Title 2";
    edge [dir = back]
    N5 -> N4 -> N3;
  }
  subgraph cluster_2 {
    label = "Title 3";
    N6
  }
  N2 -> N3 [constraint=none];
  N5 -> N6 [constraint=none];
  N1 [label = "BA_A", fillcolor="green", shape="Msquare"]
  N2 [label = "W2", fillcolor="green", shape="octagon"]
  N3 [label = "BA_A", fillcolor="green", shape="Msquare"]
  N4 [label = "W2", fillcolor="green", shape="octagon"]
  N5 [label = "W2_ERROR", fillcolor="red", shape="octagon"]
  N6 [label = "W3", fillcolor="green", shape="invtriangle"]
}
