DOT：如何在不对这些集群中的节点进行同等排名的情况下将集群放置在同一级别？

Question

我有以下 DOT 代码。它描述了五个子图（簇）。我对两个较低集群的渲染以及集群的相对位置感到满意（三个在同一级别的顶部，两个在各自顺序的底部）。然而，我希望上面三个集群中的节点是根据它们节点的内部关系进行排序的，类似于我在下面两个集群中得到的（如你所见，上面集群中的节点全部呈现在一个单行，尽管其中一些之间存在隐藏的边缘）。

我知道它们不是的原因是 rank=same; 命令。但是，如果我删除它，我将失去集群的定位。我使用命令的不同组合和其他命令（例如 clusterrank=local;）尝试了几个变体，但下面的结果保持最接近。另外 subgraph cluster ranking in dot 没有得到我想要的东西。

Answer 1

我删除了所有重复的线条、不可见的边缘和颜色属性。

然后我给它一些颜色来使我所做的可见。

来源是这样的：

digraph G {

newrank=true;
rankdir=BT;
ranksep=2;
splines=line;

subgraph cluster_z {
    label="Z";
    "TCE";
    "TNT";
    "ZAY";
    "ZCE";
    "ZIN";
    "ZNT";
    "ZON";
    "ZOW";
    "ZPP";
    "ZSF";
    "ZSS";
    "ZST";
    "ZTA";
    "ZTO";
}

subgraph cluster_y {
    rank=same;
    label="Y";
    "YCY";
    "YES";
}

subgraph cluster_w {
    rank=same;
    label="W";
    "WER";
    "WRT";
}

subgraph cluster_o {
    label="O";
    "OCE";
    "OCT";
    "OGE";
    "OIT";
    "ONT";
    "OOL";
    "OON";
    "OPE";
    "OPY";
    "ORT";
    "OTA";
    "OTO";
    "OTS";
}

subgraph cluster_e {
  label="E";
  "EUT";
  "ERT";
  "EST";
  "EON";
  "EER";
  "ERE";
  "ETO";
}

/* All the edges */
"EER" -> "ZPP";
"EER" -> "ZSF";
"EER" -> "ZTA";
"EON" -> "ZIN";
"EON" -> "ZNT";
"EON" -> "ZON";
"EON" -> "ZSF";
"EON" -> "ZTA";
"ERE" -> "ZTA";
"OCE" -> "ZCE";
"OCT" -> "ZSS";
"OGE" -> "ZIN";
"OIT" -> "ZNT";
"OIT" -> "ZSF";
"OIT" -> "ZTA";
"ONT" -> "ZON";
"OOL" -> "ZOW";
"OOL" -> "ZSS";
"OOL" -> "ZST";
"OON" -> "ZAY";
"OON" -> "ZCE";
"OON" -> "ZSF";
"OON" -> "ZTA";
"OPE" -> "ZSF";
"OPE" -> "ZTA";
"OPY" -> "ZPP";
"ORT" -> "ZSF";
"ORT" -> "ZTA";
"OTA" -> "ZAY";
"OTA" -> "ZTA";
"OTO" -> "ZTO";
"OTS" -> "ZNT";
"OTS" -> "ZTA";

/* 15 nodes from cluster_z and cluster_y and cluster_w */
{ rank = same;
    "TCE" [style = filled; color = green;]
    "TNT" [style = filled; color = green;]
    "WER" [style = filled; color = green;]
    "WRT" [style = filled; color = green;]
    "YCY" [style = filled; color = green;]
    "YES" [style = filled; color = green;]
    "ZAY" [style = filled; color = green;]
    "ZCE" [style = filled; color = green;]
    "ZIN" [style = filled; color = green;]
    "ZON" [style = filled; color = green;]
    "ZOW" [style = filled; color = green;]
    "ZPP" [style = filled; color = green;]
    "ZSS" [style = filled; color = green;]
    "ZST" [style = filled; color = green;]
    "ZTO" [style = filled; color = green;]
}

/* 10 nodes from cluster_o and cluster_e */
{ rank = same;
    "OCE" [style = filled; color = yellow;]
    "OCT" [style = filled; color = yellow;]
    "OGE" [style = filled; color = yellow;]
    "ONT" [style = filled; color = yellow;]
    "OOL" [style = filled; color = yellow;]
    "OPY" [style = filled; color = yellow;]
    "OTO" [style = filled; color = yellow;]
    "EON" [style = filled; color = yellow;]
    "EER" [style = filled; color = yellow;]
    "ERE" [style = filled; color = yellow;]
}

/* Gives cluster_z 2 rows of nodes. */
"ZSF" -> "ZTO" [color = red];

/* Gives cluster_o 4 rows of nodes. */
"OIT" -> "OON" -> "OPE" -> "ORT" [color = red];

}

图片看起来像这样：所以你可以 fiddle 随心所欲。
