如何将节点放置在neato图的顶部？

Question

是否可以强制graphviz将节点“a”置于此图的顶部？我试过neato和fdp。

digraph G { 
    "a"; 
    "b"; 
    "c"; 
    "d"; 
    "e"; 
    "a" -> "b"; 
    "a" -> "d"; 
    "a" -> "a"; 
    "b" -> "c"; 
    "c" -> "d"; 
    "d" -> "e"; 
    "e" -> "a"; 
} 

Answer 1

如果你想使用NEATO，您可以与pos属性实验：

digraph G { 
    "a" [pos="0,2!"]; 
    "b"; 
    "c"; 
    "d"; 
    "e"; 
    "a" -> "b"; 
    "a" -> "d"; 
    "a" -> "a"; 
    "b" -> "c"; 
    "c" -> "d"; 
    "d" -> "e"; 
    "e" -> "a"; 
} 

当使用dot布局，您可以切换周围边缘的方向确保a保持最佳状态：

digraph G { 
    "a"; 
    "b"; 
    "c"; 
    "d"; 
    "e"; 
    "a" -> "b"; 
    "a" -> "d"; 
    "a" -> "a"; 
    "b" -> "c"; 
    "c" -> "d"; 
    "d" -> "e"; 
    "a" -> "e" [dir=back]; 
}
