如何在Graphviz中将绿色节点排列到红色节点右侧？

问题描述

我想把图中所有绿色节点放在红色节点的右侧，用一条虚拟竖线分隔开。原本以为添加cluster能实现，但结果布局混乱了。以下是我的两个Graphviz输入文件，求可行的实现方法？

当前输入文件 

rankdir="LR"
                subgraph cluster_2 {
                        "astn-serialize-string-res" [ color="green" ]
                }
                subgraph cluster_4 {
                        "pareto-lang-lib" [ color="red", penwidth=3 ]
                }
                subgraph cluster_5 {
                        graph[color="red"]
                        "astn-unmarshall-lib" [ color="red", penwidth=3 ]
                }
                subgraph cluster_6 {
                        graph[color="red"]
                        "astn-typedhandlers-lib" [ color="red", penwidth=3 ]
                }
                subgraph cluster_7 {
                        graph[color="red"]
                        "astn-tokenizer-lib" [ color="red", penwidth=3 ]
                }
                subgraph cluster_8 {

解决方案

方法一：简化Cluster结构实现分组

你之前的Cluster嵌套层级太多，导致Graphviz布局逻辑混乱。直接把红色节点和绿色节点分别放在两个顶级Cluster里，去掉多余的子Cluster，同时隐藏Cluster的边框和标签，就能让Graphviz自动将两组节点左右分隔：

rankdir="LR"
        // 红色节点的顶级Cluster
        subgraph cluster_red {
                label=""; // 隐藏Cluster标签
                color=white; // 隐藏Cluster边框
                "pareto-lang-lib" [ color="red", penwidth=3 ]
                "astn-unmarshall-lib" [ color="red", penwidth=3 ]
                "astn-typedhandlers-lib" [ color="red", penwidth=3 ]
                "astn-tokenizer-lib" [ color="red", penwidth=3 ]
                "astn-serializer-lib" [ color="red", penwidth=3 ]
                "astn-parser-lib" [ color="red", penwidth=3 ]
                "astn-mrshlschema-lib" [ color="red", penwidth=3 ]
                "astn-marshall-lib" [ color="red", penwidth=3 ]
                "astn-loader-lib" [ color="red", penwidth=3 ]
                "astn-ide-lib" [ color="red", penwidth=3 ]
                "astn-expect-lib" [ color="red", penwidth=3 ]
        }
        // 绿色节点的顶级Cluster
        subgraph cluster_green {
                label="";
                color=white;
                "astn-serialize-string-res" [ color="green" ]
                "astn-typedhandlers-api" [ color="green" ]
                "astn-tokenconsumer-api" [ color="green" ]
                "astn-serialize-string-api" [ color="green" ]
                "astn-handlers-api" [ color="green" ]
        }
        // 原有的边定义
        "pareto-lang-lib--fountain-pen-lib" [label= "fountain-pen-lib"]
        "pareto-lang-lib" -> "pareto-lang-lib--fountain-pen-lib"
        "pareto-lang-lib" -> "astn-handlers-api"
        "pareto-lang-lib" -> "astn-expect-lib"
        "astn-unmarshall-lib" -> "astn-typedhandlers-api"
        "astn-unmarshall-lib" -> "astn-handlers-api"
        "astn-typedhandlers-lib" -> "astn-typedhandlers-api"
        "astn-typedhandlers-lib" -> "astn-tokenconsumer-api"
        "astn-typedhandlers-lib" -> "astn-handlers-api"
        "astn-typedhandlers-lib" -> "astn-expect-lib"
        "astn-typedhandlers-api" -> "astn-handlers-api"
        "astn-tokenizer-lib" -> "astn-tokenconsumer-api"
        "astn-serializer-lib" -> "astn-serialize-string-api"
        "astn-serializer-lib" -> "astn-handlers-api"
        "astn-serialize-string-res" -> "astn-serialize-string-api"
        "astn-parser-lib" -> "astn-tokenconsumer-api"
        "astn-parser-lib" -> "astn-handlers-api"
        "astn-mrshlschema-lib" -> "pareto-lang-lib"
        "astn-mrshlschema-lib" -> "astn-typedhandlers-api"
        "astn-mrshlschema-lib" -> "astn-handlers-api"
        "astn-marshall-lib" -> "astn-typedhandlers-api"
        "astn-marshall-lib" -> "astn-tokenconsumer-api"
        "astn-marshall-lib" -> "astn-parser-lib"
        "astn-loader-lib" -> "astn-unmarshall-lib"
        "astn-loader-lib" -> "astn-tokenizer-lib"
        "astn-loader-lib" -> "astn-parser-lib"
        "astn-loader-lib" -> "astn-mrshlschema-lib"
        "astn-loader-lib" -> "astn-expect-lib"
        "astn-ide-lib" -> "astn-typedhandlers-api"
        "astn-expect-lib" -> "astn-handlers-api"
}

方法二：用不可见节点+Rank约束强制分隔

如果需要更精确的位置控制，可以给红色节点和绿色节点分别设置同Rank，再添加不可见的中间节点和边，强制红色在左、绿色在右：

rankdir="LR"
        // 红色节点组，强制同Rank
        subgraph red_group {
                rank=same;
                "pareto-lang-lib" [ color="red", penwidth=3 ]
                "astn-unmarshall-lib" [ color="red", penwidth=3 ]
                "astn-typedhandlers-lib" [ color="red", penwidth=3 ]
                "astn-tokenizer-lib" [ color="red", penwidth=3 ]
                "astn-serializer-lib" [ color="red", penwidth=3 ]
                "astn-parser-lib" [ color="red", penwidth=3 ]
                "astn-mrshlschema-lib" [ color="red", penwidth=3 ]
                "astn-marshall-lib" [ color="red", penwidth=3 ]
                "astn-loader-lib" [ color="red", penwidth=3 ]
                "astn-ide-lib" [ color="red", penwidth=3 ]
                "astn-expect-lib" [ color="red", penwidth=3 ]
        }
        // 绿色节点组，强制同Rank
        subgraph green_group {
                rank=same;
                "astn-serialize-string-res" [ color="green" ]
                "astn-typedhandlers-api" [ color="green" ]
                "astn-tokenconsumer-api" [ color="green" ]
                "astn-serialize-string-api" [ color="green" ]
                "astn-handlers-api" [ color="green" ]
        }
        // 添加不可见分隔节点，强制分组顺序
        separator [style=invisible]
        "astn-expect-lib" -> separator [style=invisible]
        separator -> "astn-handlers-api" [style=invisible]

        // 原有的边定义
        "pareto-lang-lib--fountain-pen-lib" [label= "fountain-pen-lib"]
        "pareto-lang-lib" -> "pareto-lang-lib--fountain-pen-lib"
        "pareto-lang-lib" -> "astn-handlers-api"
        "pareto-lang-lib" -> "astn-expect-lib"
        "astn-unmarshall-lib" -> "astn-typedhandlers-api"
        "astn-unmarshall-lib" -> "astn-handlers-api"
        "astn-typedhandlers-lib" -> "astn-typedhandlers-api"
        "astn-typedhandlers-lib" -> "astn-tokenconsumer-api"
        "astn-typedhandlers-lib" -> "astn-handlers-api"
        "astn-typedhandlers-lib" -> "astn-expect-lib"
        "astn-typedhandlers-api" -> "astn-handlers-api"
        "astn-tokenizer-lib" -> "astn-tokenconsumer-api"
        "astn-serializer-lib" -> "astn-serialize-string-api"
        "astn-serializer-lib" -> "astn-handlers-api"
