GraphViz - 如何连接子图? [英] GraphViz - How to connect subgraphs?
问题描述
在用于 GraphViz
的 DOT
语言中,我试图表示依赖关系图。我需要能够在容器中有节点,并且能够使节点和/或容器依赖于其他节点和/或容器。
In the DOT
language for GraphViz
, I'm trying to represent a dependency diagram. I need to be able to have nodes inside a container and to be able to make nodes and/or containers dependent on other nodes and/or containers.
我正在使用子图
来表示我的容器。节点链接工作正常,但我不知道如何连接子图。
I'm using subgraph
to represent my containers. Node linking works just fine, but I can't figure out how to connect subgraphs.
给定下面的程序,我需要能够连接 cluster_1
和 cluster_2
带箭头,但我尝试过的任何内容都会创建新节点而不是连接集群:
Given the program below, I need to be able to connect cluster_1
and cluster_2
with an arrow, but anything I've tried creates new nodes instead of connecting the clusters:
digraph G {
graph [fontsize=10 fontname="Verdana"];
node [shape=record fontsize=10 fontname="Verdana"];
subgraph cluster_0 {
node [style=filled];
"Item 1" "Item 2";
label = "Container A";
color=blue;
}
subgraph cluster_1 {
node [style=filled];
"Item 3" "Item 4";
label = "Container B";
color=blue;
}
subgraph cluster_2 {
node [style=filled];
"Item 5" "Item 6";
label = "Container C";
color=blue;
}
// Renders fine
"Item 1" -> "Item 2";
"Item 2" -> "Item 3";
// Both of these create new nodes
cluster_1 -> cluster_2;
"Container A" -> "Container C";
}
推荐答案
DOT用户手册给出了以下图形的示例群集之间的边缘群集
The DOT user manual gives the following example of a graph with clusters with edges between clusters
digraph G {
compound=true;
subgraph cluster0 {
a -> b;
a -> c;
b -> d;
c -> d;
}
subgraph cluster1 {
e -> g;
e -> f;
}
b -> f [lhead=cluster1];
d -> e;
c -> g [ltail=cluster0,lhead=cluster1];
c -> e [ltail=cluster0];
d -> h;
}
以及节点和群集之间的边界。
and edges between nodes and clusters.
