如何在GraphViz中双向制作边缘? [英] How to make an edge with both direction in GraphViz?

问题描述

如何在GraphViz中制作两个方向的边?

How to make an edge with both direction in GraphViz?

我正在尝试制作两个方向的弯曲边缘.

I am trying to make an curved edge with both direction.

但是我唯一能做的是:

我想使x1和x2之间的边沿两个方向弯曲.

I want to make the edge between x1 and x2 curved with both direction.

我使用的代码:

digraph {

rankdir=LR

node [shape=box ]
x1;x2
node [shape=oval ]
y

x1->y[dir=back label=0.77]
x2->y[dir=back label=0.42]

x1:w -> x2:w[dir=both constraint=false]

}

我将不胜感激.

推荐答案

我认为应该有一个更好的解决方案，但以下对我有用:

I think there should be a better solution but the following did work for me:

digraph {

rankdir=LR

node [shape=box ]
x1;x2
node [shape=oval ]
y

x1->y[dir=back label=0.77]
x2->y[dir=back label=0.42]

x1:w -> x2:w[dir=both constraint=false]
x2:w -> x1:w[dir=both constraint=false]
}

基于更改点中边缘方向的答案:

digraph g {

rankdir=LR

node [shape=box ]
{rank=same x1;x2}
node [shape=oval ]
y

x1 -> y[dir=back label=0.77]
x2 -> y[dir=back label=0.42]

x1:w -> x2:w[dir=both label=0.34]

}
