Graphviz：集群中的排序节点

Question

我正在研究一个自动生成的 Graphviz（因此它需要是一个通用的解决方案，而不是针对这个特定的例子）。它绘制了网络的拓扑结构。但集群内的结果看起来没有组织。

拓扑结构如下：

这是相关代码：

digraph G {

splines=polyline;

subgraph cluster_sh5sl8 {
    style=filled;
    color=lightgrey;
    node [style=filled,color=white];
    sh5sl8_L1 [label = "L1"];
    label = "5/8";
}
subgraph cluster_sh5sl10 {
    style=filled;
    color=lightgrey;
    node [style=filled,color=white];
    sh5sl10_L1 [label = "L1"];
    label = "5/10";
}
subgraph cluster_sh5sl12 {
    style=filled;
    color=lightgrey;
    node [style=filled,color=white];
    sh5sl12_L1 [label = "L1"];
    label = "5/12";
}
subgraph cluster_sh5sl14 {
    style=filled;
    color=lightgrey;
    node [style=filled,color=white];
    sh5sl14_L1 [label = "L1"];
    label = "5/14";
}
subgraph cluster_sh5sl16 {
    style=filled;
    color=lightgrey;
    node [style=filled,color=white];
    sh5sl16_L1 [label = "L1"];
    label = "5/16";
}
subgraph cluster_sh6sl3 {
    style=filled;
    color=lightgrey;
    node [style=filled,color=white];
    sh6sl3_L1 [label = "L1"];
    label = "6/3";
}
subgraph cluster_sh6sl8 {
    style=filled;
    color=lightgrey;
    node [style=filled,color=white];
    sh6sl8_L1 [label = "L1"];
    label = "6/8";
}
subgraph cluster_sh6sl10 {
    style=filled;
    color=lightgrey;
    node [style=filled,color=white];
    sh6sl10_L1 [label = "L1"];
    label = "6/10";
}
subgraph cluster_sh6sl12 {
    style=filled;
    color=lightgrey;
    node [style=filled,color=white];
    sh6sl12_L1 [label = "L1"];
    label = "6/12";
}
subgraph cluster_sh6sl14 {
    style=filled;
    color=lightgrey;
    node [style=filled,color=white];
    sh6sl14_L1 [label = "L1"];
    label = "6/14";
}
subgraph cluster_sh6sl16 {
    style=filled;
    color=lightgrey;
    node [style=filled,color=white];
    sh6sl16_L1 [label = "L1"];
    label = "6/16";
}
subgraph cluster_sh30sl1 {
    rank=same;
    style=filled;
    color=lightgrey;
    node [style=filled,color=white];
    sh30sl1_9600 [label = "9600"]; sh30sl1_9590 [label = "9590"]; sh30sl1_9580 [label = "9580"]; sh30sl1_9570 [label = "9570"]; sh30sl1_9560 [label = "9560"]; sh30sl1_9280 [label = "9280"]; sh30sl1_9270 [label = "9270"]; sh30sl1_9260 [label = "9260"]; sh30sl1_9250 [label = "9250"]; sh30sl1_9220 [label = "9220"]; sh30sl1_9190 [label = "9190"]; sh30sl1_OMD [label = "OMD"];
    label = "30/1";
}

sh30sl1_9570 -> sh5sl8_L1;
sh30sl1_9560 -> sh5sl10_L1;
sh30sl1_9280 -> sh5sl12_L1;
sh30sl1_9270 -> sh5sl14_L1;
sh30sl1_9260 -> sh5sl16_L1;
sh30sl1_9220 -> sh6sl3_L1;
sh30sl1_9250 -> sh6sl8_L1;
sh30sl1_9190 -> sh6sl10_L1;
sh30sl1_9600 -> sh6sl12_L1;
sh30sl1_9590 -> sh6sl14_L1;
sh30sl1_9580 -> sh6sl16_L1;
sh6sl12_L1 -> sh30sl1_9600;
sh6sl14_L1 -> sh30sl1_9590;
sh6sl16_L1 -> sh30sl1_9580;
sh5sl8_L1 -> sh30sl1_9570;
sh5sl10_L1 -> sh30sl1_9560;
sh5sl12_L1 -> sh30sl1_9280;
sh5sl14_L1 -> sh30sl1_9270;
sh5sl16_L1 -> sh30sl1_9260;
sh6sl8_L1 -> sh30sl1_9250;
sh6sl3_L1 -> sh30sl1_9220;
}

请注意，我使用的是 FDP，但如果可以的话，我也可以使用其他任何东西。目前，FDP 给了我最好的结果。

如何订购？

我已经尝试过 clusterrank, ranksep, nodesep, constraint=false，或者以其他顺序调用它们，等等。我尝试创建一个不可抗拒的节点和 link 集群中的每个其他节点以使它们等距，但它没有工作。

我还没有可以处理生成的结果的答案 - 我有一个类似的问题，我可以自己修改 graphviz 文件：

和

<graphviz>
  digraph hierachy {
    rankdir="LR"
    graph [ordering="out"];
    subgraph cluster_Hierachie {
      label="Hierachie"
      n0 
      n10000 
      n20000 
      n30000 
      n40000 
      n50000 
      n0->n10000
      n0->n20000
      n0->n30000
      n0->n40000
      n0->n50000
   }
  }
</graphviz>

呈现为：

到目前为止找到以下链接：

Preventing graphviz from rearranging nodes

请注意关于如何指定的不同建议"ordering=out"

digraph g {
  ordering=out ;

或

digraph bt {
  graph [ordering="out"];

none 这些对我有用，尽管 got 1 upvote and 有 2 个赞成票

http://www.graphviz.org/content/ordering-edges 建议使用

rank=same

所以我尝试了：

<graphviz>
  digraph hierachy {
    rankdir="LR"
    graph [ordering="out"];

    subgraph cluster_Hierachie {
      label="Hierachie"
      n0 
      n10000 
      n20000 
      n30000 
      n40000 
      n50000 
      n0->n10000
      n0->n20000
      n0->n30000
      n0->n40000
      n0->n50000
      {
        rank=same;n0;n10000;n20000;n30000;n40000;n50000
      }
   }

  }
</graphviz>

建议添加

style=invis
{  rank=same  0 -- 1 [style=invis]
}

节点。我试过了无济于事，最后做了

<graphviz>
  digraph hierachy {
    rankdir="LR"
    graph [ordering="out"];

    subgraph cluster_Hierachie {
      label="Hierachie"
      n0 
      n10000 
      n20000 
      n30000 
      n40000 
      n50000 
      n0->n50000
      n0->n40000
      n0->n30000
      n0->n20000
      n0->n10000
   }
  }
</graphviz>

呈现为：

考虑到集群中反向排序的奇怪行为，我认为这是一个有效的解决方法。
