graphviz - graphviz 中的自循环边太短且难看

Question

我用graphviz画了一张图。请参阅FSM 。我认为它很丑，因为自环边缘太短。边缘的属性“minlen”对我不起作用。我尝试了节点的几个端口，但除了我当前的实现之外，一切都显示出一团糟。你有什么好主意给我吗？代码在这里:

digraph finite_state_machine {
rankdir=LR;
size="8,2"
fontname="Verdana"
node [shape = doublecircle]; Idle;
node [shape = circle,nodesep = "2.0"];
Working:s -> Working:s [ label = "response[j]?" ,minlen = 50000];
Idle -> Working [ label = "boot" ];
Working:n -> Working:n [ label = "sendtx[i]!",minlen = 50000 ];
Working:e -> Working:e [ label = "qry!" ,minlen = 50000];

}

Answer 1

添加 nodesep=1; 会使循环变得更大，但不是更好。所以这会有所帮助:

digraph finite_state_machine {
  rankdir=LR;
  size="8,2"
  fontname="Verdana"
  node [shape = doublecircle]; Idle;
  node [shape = circle,nodesep = "2.0"];
  Working:s -> Working:s [ label = "response[j]?" ,minlen = 50000];
  Idle -> Working [ label = "boot" ];
  Working:n -> Working:n [ label = "sendtx[i]!" ];
  Working:e -> Working:e [ label = "qry!"];
  nodesep=1;
}

会产生如下内容:
