我有一些相对简单的(自动生成的)graphviz点格式的图。这些显示了通过状态机的路径,但是当我希望图形处于状态顺序时,点有一个令人困惑的习惯,即确定两个节点必须处于同一等级。我已经尝试了很多设置(包括下面列出的:n
和:s
和weight
),但是我无法说服点将第三状态置于第四状态之上。
我在很多图形中都遇到了这个问题:点内部似乎有些东西决定了,如果两个节点处于同一等级,那会更好,并且没有任何办法可以覆盖它。我什至有代码指定一个节点应该是rank=sink
,但是dot决定无论如何都要在其下放置另一个节点。
有没有什么方法可以建议点比其他任何约束更重要?
用于生成图形的代码如下所示:
digraph {
ERROR [label="Error"];
FirstSTATE [label="Initial State" URL="\ref FirstSTATE"];
FirstSTATE -> SecondSTATE;
SecondSTATE [label="Second State" URL="\ref SecondSTATE"];
SecondSTATE -> ThirdSTATE;
ThirdSTATE [label="Third State" URL="\ref ThirdSTATE"];
FourthSTATE [label="Fouth State?" shape="diamond"];
ThirdSTATE:s -> FourthSTATE:n [weight=50];
FourthSTATE -> FifthSTATE [label="Yes" ];
FourthSTATE -> ThirdSTATE [label="No"];
FifthSTATE [label="Fifth State" URL="\ref FifthSTATE"];
SixthSTATE [label="Sixth State?" shape="diamond"];
SixthSTATE -> ERROR [label="Yes" ];
SixthSTATE -> SeventhSTATE [label="No"];
FifthSTATE -> SixthSTATE;
SeventhSTATE [label="Seventh State" URL="\ref SeventhSTATE"];
SeventhSTATE -> EighthSTATE;
EighthSTATE [label="Eighth State" URL="\ref EighthSTATE"];
NinthSTATE [label="Ninth State?" shape="diamond"];
NinthSTATE -> TenthSTATE [label="Yes" ];
NinthSTATE -> EighthSTATE [label="No"];
EighthSTATE -> NinthSTATE;
TenthSTATE [label="Tenth State" URL="\ref TenthSTATE"];
EleventhSTATE [label="Eleventh State?" shape="diamond"];
EleventhSTATE -> ERROR [label="Yes" ];
EleventhSTATE -> TwelfthSTATE [label="No" ];
TenthSTATE -> EleventhSTATE;
TwelfthSTATE [label="Twelfth State" URL="\ref TwelfthSTATE"];
}
最佳答案
使用“constraint = false”。
http://www.graphviz.org/doc/info/attrs.html#d:constraint
在您的图形中:
FourthSTATE -> ThirdSTATE [label="No" constraint=false] ;
digraph {
ERROR [label="Error"];
FirstSTATE [label="Initial State" URL="\ref FirstSTATE"];
FirstSTATE -> SecondSTATE;
SecondSTATE [label="Second State" URL="\ref SecondSTATE"];
SecondSTATE -> ThirdSTATE;
ThirdSTATE [label="Third State" URL="\ref ThirdSTATE"];
FourthSTATE [label="Fouth State?" shape="diamond"];
ThirdSTATE -> FourthSTATE;
FourthSTATE -> FifthSTATE [label="Yes" ];
FourthSTATE -> ThirdSTATE [label="No" constraint=false] ;
FifthSTATE [label="Fifth State" URL="\ref FifthSTATE"];
SixthSTATE [label="Sixth State?" shape="diamond"];
SixthSTATE -> ERROR [label="Yes" ];
SixthSTATE -> SeventhSTATE [label="No"];
FifthSTATE -> SixthSTATE;
SeventhSTATE [label="Seventh State" URL="\ref SeventhSTATE"];
SeventhSTATE -> EighthSTATE;
EighthSTATE [label="Eighth State" URL="\ref EighthSTATE"];
NinthSTATE [label="Ninth State?" shape="diamond"];
NinthSTATE -> TenthSTATE [label="Yes" ];
NinthSTATE -> EighthSTATE [label="No"];
EighthSTATE -> NinthSTATE;
TenthSTATE [label="Tenth State" URL="\ref TenthSTATE"];
EleventhSTATE [label="Eleventh State?" shape="diamond"];
EleventhSTATE -> ERROR [label="Yes" ];
EleventhSTATE -> TwelfthSTATE [label="No" ];
TenthSTATE -> EleventhSTATE;
TwelfthSTATE [label="Twelfth State" URL="\ref TwelfthSTATE"];
}
