如何让点并排绘制连接的子图？

Question

这是生成的图表当前的样子： 这是代码：

  digraph {
  rankdir=TB;
  subgraph cluster01 {
    label="1.fázis"

    aSTART;
    node [shape = doublecircle]; a001; 
    node [shape = ellipse];

    aSTART -> a0 [ penwidth = 3 label = "0" ];
    a0 -> a00 [ penwidth = 3 label = "0" ];  
    a00 -> a001 [ penwidth = 3 label = "1" ];


    a0 -> aSTART [ label = "1" ];  
    a00 -> a00 [ label = "0" ];  
    a001 -> a0 [ label = "0"];
    a001 -> aSTART [ label = "1"];
    aSTART -> aSTART [ label = "1"];  
  }
  subgraph cluster02
  {
  label="2.fázis"
  bSTART; b1; b11;
  node [shape = doublecircle]; b111;
  node [shape = ellipse];

  bSTART -> b1 [ penwidth = 3 label = "1" ];
  b1 -> b11 [ penwidth = 3 label = "1" ];  
  b11 -> b111 [ penwidth = 3 label = "1" ];

  b1 -> bSTART [ label = "0" ];  
  b11 -> bSTART [ label = "0" ];  
  b111 -> bSTART [ label = "0"];
  bSTART -> bSTART [ label = "0"];

  b111 -> b111 [label = "1"];
  }

  subgraph cluster03
  {
  label="3.fázis";  

    cSTART; c0; c1; c01; c10;
    node [shape = doublecircle]; c010; c100;
    node [shape = ellipse];

    cSTART -> c0 [ penwidth = 3 label = "0" ];
    c0 -> c01 [ label = "1" ];  
    c01 -> c010 [ penwidth = 3 label = "0" ];

    cSTART -> c1 [ label = "1" ];  
    c1 -> c10 [ penwidth = 3 label = "0" ];    
    c10 -> c100 [ label = "0" ];    

    c0 -> c1 [ penwidth = 3 label = "1" ];
    c01 -> c1 [ label = "1" ];
    c1 -> c1 [label = "1"];

    c10 -> c01 [ penwidth = 3 label = "1"];

    c010 -> c100 [penwidth = 3 label = "0"];
    c010 -> c01 [label = "1"];

    c100 -> c01 [label = "1"];
    c100 -> c0 [label = "0"];

  }

  a001 -> b1 [color = "red" style = "dashed"];
  b111 -> c1 [color = "red" style = "dashed"];
}

如果我删除 2 条红线，它会按照我想要的方式排列：

我怎样才能让它像这样排列并且同时有两条红线？

Answer 1

你可以添加

{
   rank=same;
   aSTART;
   bSTART
   cSTART;
}

在您的子图 cluster03 之后。 Dot 会给你一个警告，但会按照你想要的方式绘制：

D:\Code\funfunfun>dot -Tpng -oso1.png -Gcharset=latin1 so1.dot
Warning: aSTART was already in a rankset, ignored in cluster _anonymous_0
Warning: bSTART was already in a rankset, ignored in cluster _anonymous_0
Warning: cSTART was already in a rankset, ignored in cluster _anonymous_0

Answer 2

您应该在两条红色边上使用constraint=false 属性。

如果为 false，则不使用边对节点进行排序。
