orderGraphviz-固定子图 [英] orderGraphviz - fixed subgraphs

问题描述

我喜欢这样创建3列图形:

I like to create a 3 column graph like this:

代码:

digraph g {
rankdir="LR";
node[shape = circle, fontsize=14];
fontsize=18;
labeljust="l";

{ rank=same;
}

edge[style=invis, fontsize=12];
subgraph clusterA {
    a->b;
    label="A";
}
subgraph clusterC {
  e->f->g;
    label="C";
}

subgraph clusterB {
 c->d;
label="B";
}

}

我想用子图A，C，B的顺序创建一个图.如何在不保留A–C–B的顺序的情况下向该图添加关系(例如c-> f;和b-> g;)?

I want to create a graph with the subgraphs A,C,B ordering. How can I add relations to this graph (ex. c->f; and b->g;) without the remaining the order of A--C--B?

推荐答案

您可以尝试使用 constraint=false 添加不应该影响布局的边.在最后一个群集之后，插入以下内容:

You may try adding the edges which are not supposed to influence the layout with constraint=false. After the last cluster, insert something like:

edge[constraint=false, style=solid];
c->f;
b->g;

如果集群仍然重新排序，则可以添加不可见的边缘(确保constraint=true)以强制布局:

If the clusters get reordered anyway, you may add invisible edges (make sure that constraint=true) to enforce the layout:

c -> e [constraint=true, style=invis];
e -> a [constraint=true, style=invis];
