graph - 子图之间的距离增加

Question

我有以下代码:

digraph g {
graph [rankdir="LR" ,compound="true" ];
    subgraph cluster0 {
        graph [label="Ready\n\nAllowed Purchaser Operations:\noperation1,operation2\n\nAllowed Supplier Operations:\noperation1,operation3"  ];
        1 [ shape="none" ,fontcolor="white"  ];
    };
    subgraph cluster2 {
        graph [label="Paused\n\nAllowed Purchaser Operations:\noperation1,operation3\n\nAllowed Supplier Operations:\noperation2,operation3" ];
        3 [ shape="none" ,fontcolor="white"  ];
    };
    subgraph cluster4 {
        graph [label="Completed\n\nAllowed Purchaser Operations:\noperation4\n\nAllowed Supplier Operations:\noperation4" ];
        5 [ shape="none" ,fontcolor="white"  ];
    };
    1 -> 3 [ ltail="cluster0" ,lhead="cluster2" ,comment="6"  ];
    1 -> 5 [ ltail="cluster0" ,lhead="cluster4" ,comment="7"  ];
    3 -> 1 [ ltail="cluster2" ,lhead="cluster0" ,comment="8"  ];
    3 -> 5 [ ltail="cluster2" ,lhead="cluster4" ,comment="9"  ];
}

我想增加子图之间的距离。我尝试使用 len， margin， pad，但是我尝试过的语法不起作用。有人可以帮我吗？

我认为您正在寻找的(确实是Emden指出)确实是nodesep和ranksep属性。

graph [nodesep=6, ranksep=4];

结果将是:
