GraphViz - 在多行中创建集群簇

Question

我真的很感谢你对我想要的图表的帮助。我想从一个起始集群为其他许多集群提供标签，而这些集群又应该组织成多行。

直到这一刻我写了下面的代码：

digraph g{ 
rankdir="TB"; 
compound=true; 

subgraph cluster0{ 
label="Cluster 0"; 
a0->b0; 
b0->c0; 
a0->c0; 
} 

subgraph cluster1{ 
label="Cluster 1"; 
a1->b1; 
b1->c1; 
a1->c1; 
} 

subgraph cluster2{ 
label="Cluster 2"; 
a2->b2; 
b2->c2; 
a2->c2; 
} 


subgraph cluster3{ 
label="Cluster 3"; 
a3->b3; 
b3->c3; 
a3->c3; 
} 

subgraph cluster4{ 
label="Cluster 4"; 
a4->b4; 
b4->c4; 
a4->c4; 
} 

a0->a1 [ltail=cluster0,lhead=cluster1]; 
a0->a2 [ltail=cluster0,lhead=cluster2]; 
a0->a3 [ltail=cluster0,lhead=cluster3]; 
a0->a4 [ltail=cluster0,lhead=cluster4]; 

} 

尽管此代码生成我的集群和适当的互连他们，遗憾的是所有的集群（即集群1,2,3和4）在而我希望群集1和群集2位于一行，群集3和群集4位于另一行，恰好位于包含群集1和群集2的行的下方。

虽然群集是使用不可见链接组织在一起，它们没有正确对齐（列），而且内部节点序列似乎纠结（见例如，稍微更复杂的情况下，我想标记4为总是在顶部，其中剩余的节点1,2和3应该被放置在相应的顺序从左至右）的节点以下

} 

是否有任何方式，我可以实现使用点？

非常感谢您的帮助提前！

你可以通过添加一些可见边尝试：

c0->a1 [style=invis]; 
c0->a2 [style=invis]; 
c1->a3 [style=invis]; 
c2->a4 [style=invis]; 

，并从那里，如果需要进一步提高。

这确保集群位于不同的等级上。
