Graphviz中群集之间的直边

问题描述

我正在尝试在Graphviz的群集之间建立一条不影响排名的边缘.

I'm trying to have an edge between clusters in Graphviz where the edge does not affect the ranking.

这看起来不错:

digraph {
  subgraph clusterX {
    A
    B
  }

  subgraph clusterY {
    C
    D
  }

  A -> B
  B -> C [constraint=false]
  C -> D
}

但是，当我在C -> D边缘添加标签时，B -> C边缘会尝试绕过所述标签(看起来很丑).

However when I add a label to the C -> D edge the B -> C edge tries to circumvent said label (which looks ugly).

digraph {
  subgraph clusterX {
    A
    B
  }

  subgraph clusterY {
    C
    D
  }

  A -> B
  B -> C [constraint=false]
  C -> D [label=yadda]
}

有什么想法可以使边缘从B到C保持笔直?

Any idea how I can keep the edge from B to C straight?

推荐答案

最简单的方法是在点文件中添加splines=false-这会强制将边缘渲染为直线:

The easiest way to achieve this is to add splines=false to the dot file - this forces the rendering of the edges to be straight lines:

digraph {
 splines=false;
 subgraph clusterX {
    A;
    B;
 }

 subgraph clusterY {
    C;
    D;
 }

 A -> B;
 B -> C [constraint=false];
 C -> D [label=yadda];
}

输出:
