我有以下 graphviz 文件。现在,边缘标签放置在水平线上,但我希望将节点放置在水平线上。我怎样才能做到这一点?
digraph finite_state_machine {
node [shape = doublecircle]; q_5;
node [shape = circle];
q_1 -> q_2 [ label = "." ];
q_1 -> q_2 [ label = "\epsilon" ];
q_2 -> q_1 [ label = "\epsilon" ];
q_2 -> q_3 [ label = "a" ];
q_3 -> q_4 [ label = "^\wedge a" ];
q_3 -> q_4 [ label = "\epsilon" ];
q_4 -> q_3 [ label = "\epsilon" ];
q_4 -> q_5 [ label = "b" ];
}
这是它目前的样子:
