子图水平，其节点垂直对齐 [英] Subgraphs horizontal and its nodes vertical aligned

问题描述

我在组织子图水平而在子图内部垂直时遇到问题.它们(子图和节点)全部都在一条线上(水平或垂直).

I have problems to organize my subgraphs horizontal and the nodes inside the subgraphs vertical. All of them (subgraphs and nodes) are just on one line (horizontal or vertical).

digraph G {
  rankdir = LR;
  subgraph cluster_0 {
    rankdir = TB;
    node [style=filled];
    label = "Title 1";
    color=black
    N1 -> N2;
  }
  subgraph cluster_1 {
    rankdir = TB;
    node [style=filled];
    label = "Title 2";
    color=black
    N3 -> N4 -> N5;
  }
  subgraph cluster_2 {
    rankdir = TB;
    node [style=filled];
    ...
  }
  ...

  N2 -> N3;
  ...

  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"]
  ...
}

我也尝试过使用{rank=same; N1; N3; ...;}.这会将节点从子图中移出.

I also tried with {rank=same; N1; N3; ...;}. This take the nodes out of the subgraphs.

推荐答案

您可以使用类似的方法:

You can use something like that:

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"]
}
