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。我尝试过使用len, margin, pad，但我尝试过的语法不起作用。有人可以帮助我吗？
我认为你正在寻找什么（如Emden https://stackoverflow.com/users/2348178/emden指出）确实是nodesep http://www.graphviz.org/doc/info/attrs.html#d:nodesep and ranksep http://www.graphviz.org/doc/info/attrs.html#d:ranksep属性。
graph [nodesep=6, ranksep=4];
结果将是：
