Marapet的代码非常接近(参见:http://i.imgur.com/ElzSl.png ).我接受了他的回答.

Answer 1

我将为转换条件创建节点:

digraph g{
  Opened[label="1\nOpened\nE: open door"];
  Closed[label="2\nClosed\nE: closed door"];
  node[shape=plaintext];

  Opened -> close_door[arrowhead=none];
  close_door -> Closed;
  Opened -> open_door[dir=back];
  open_door -> Closed[arrowhead=none];
}
