GraphViz-定义簇的顺序

发布于 2025-01-25 21:34:26 字数 675 浏览 3 评论 0原文

我正在GraphViz/dot中生成群集节点。简化示例：

digraph G {
    rankdir=LR

    n2a->n3
    n1->n2b
    n2b->n2a
    n2b->n3
    n3->n1

    subgraph cluster_1 { label="cluster_1" n1 }
    subgraph cluster_2 { label="cluster_2" n2a n2b }
    subgraph cluster_3 { label="cluster_3" n3 }
}

我想强迫点始终以从右到左的升序将簇放置（左侧的群集1，接下来是群集2等），但是按DOT指示，将每个群集内的节点排列在每个群集中自动地。

我尝试使用clusterRank，等级，newrank，benteraind = false发生。怎么办？

I'm generating clustered nodes in graphviz/dot. Simplified example:

digraph G {
    rankdir=LR

    n2a->n3
    n1->n2b
    n2b->n2a
    n2b->n3
    n3->n1

    subgraph cluster_1 { label="cluster_1" n1 }
    subgraph cluster_2 { label="cluster_2" n2a n2b }
    subgraph cluster_3 { label="cluster_3" n3 }
}

I want to force dot to always put the clusters in ascending order from right to left (cluster 1 in the left, next is cluster 2 etc.), but to arrange the nodes inside each cluster as dot dictates automatically.

I tried to play with clusterrank, rank, newrank, constraint=false and couldn't manage to make it happen. How can it be done?

您可以通过添加边缘来建立每个群集中每个节点的等级来“强制”这一情况。排名都比cluster_2中的每个节点较低。

digraph G {
    rankdir=LR

    n2a->n3
    n1->n2b
    n2b->n2a
    n2b->n3
    n3->n1

    subgraph cluster_1 { label="cluster_1" n1 }
    subgraph cluster_2 { label="cluster_2" n2a n2b }
    subgraph cluster_3 { label="cluster_3" n3 }
    // simple-minded solution - force clusters based on (added) rank
    edge [style=invis]
    {n1} -> {n2a n2b} -> {n3}
}

cluster_1中的每个节点的

You can "force" this to happen by adding edges to establish rank of every node in every cluster. Every node in cluster_1 has a lesser rank than every node in cluster_2, etc. Like so:

digraph G {
    rankdir=LR

    n2a->n3
    n1->n2b
    n2b->n2a
    n2b->n3
    n3->n1

    subgraph cluster_1 { label="cluster_1" n1 }
    subgraph cluster_2 { label="cluster_2" n2a n2b }
    subgraph cluster_3 { label="cluster_3" n3 }
    // simple-minded solution - force clusters based on (added) rank
    edge [style=invis]
    {n1} -> {n2a n2b} -> {n3}
}
