Graphviz Dot，混合有向和无向 [英] Graphviz Dot, mix directed and undirected

问题描述

对于我的应用程序，我需要同时表示(在同一张图中)两种关系:一种是对称的，另一种不是.

For my application I need to represent simultaneously (on the same graph) two relations: one is simmetric, the other is not.

目标:

• 理想情况下，这两种关系应该导致边缘具有不同的颜色；
• 对于对称关系，我不希望有双边；

有没有办法用 dot 做到这一点?

Is there a way of doing this with dot?

推荐答案

digraph {

    A; B; C

    subgraph Rel1 {
        edge [dir=none, color=red]
        A -> B -> C -> A
    }

    subgraph Rel2 {
        edge [color=blue]

        B -> C
        C -> A
    }

}
