我有这个gv代码,
我想要水平顺序: 12 13 14 15 23 24
但我明白了:
23 13 12 24 14 15
graph "tree" {
node [shape=plaintext];
1 [label = "1"]
2 [label = "2"]
3 [label = "3"]
4 [label = "4"]
5 [label = "5"]
12 [label = "12"]
13 [label = "13"]
14 [label = "14"]
15 [label = "15"]
23 [label = "23"]
24 [label = "24"]
1 -- 12;
2 -- 12;
1 -- 13;
3 -- 13;
1 -- 14;
4 -- 14;
1 -- 15;
5 -- 15;
2 -- 23;
3 -- 23;
2 -- 24;
4 -- 24;}
解决方案:Force the left to right order of nodes in graphviz?对于这种情况不起作用(排序节点不是边缘)。
如果我添加:
{rank = same; 12 13 14 15 23 24; rankdir=LR;}
我们得到相同的无序节点:

dot -T png test.gv > test.png

最简单的方法是添加'隐形'(白色,无箭头)边缘。
这将鼓励点按顺序对齐节点。
graph "tree" {
node [shape=plaintext];
1 [label = "1"]
2 [label = "2"]
3 [label = "3"]
4 [label = "4"]
5 [label = "5"]
12 [label = "12"]
13 [label = "13"]
14 [label = "14"]
15 [label = "15"]
23 [label = "23"]
24 [label = "24"]
1 -- 12;
2 -- 12;
1 -- 13;
3 -- 13;
1 -- 14;
4 -- 14;
1 -- 15;
5 -- 15;
2 -- 23;
3 -- 23;
2 -- 24;
4 -- 24;
// 'white' (invisible on white background) edges, weight to encourage order
// results in tidiest graph with horizontal nodes in desired order.
edge [color=white,weight=4,arrowhead=none,arrowtail=none];
12 -- 13 -- 14 -- 15 -- 23 -- 24 -- 25 -- 34 -- 35 -- 45;
{rank = same; 12 13 14 15 23 24 25 34 35 45; rankdir=LR;}
}
