Graphviz子圖順序

Question

我試圖創建一個帶點的圖形網絡。和Graphiz。

到目前爲止，這是我的代碼：

graph { 
rankdir = LR; 
splines=line;  

subgraph cluster_1{    
    1; 2; 
} 
subgraph cluster_2{ 
    b; c; 
} 

subgraph cluster_3{ 
color = white  
    10;11; 
} 

b -- {1 2 10 11}[color = blue]; 
c -- {1 2 10 11}[color = yellow]; 



1[label = "1", style = filled, fillcolor = grey91] 
2[label = "2", style = filled, fillcolor = grey91] 
b[label = "B", style = filled, fillcolor = blue] 
c[label = "C", style = filled, fillcolor = yellow] 
10[label = "10", style = filled, fillcolor = grey91] 
11[label = "11", style = filled, fillcolor = grey91] 

} 

這就是我得到：

這是我想獲得什麼：

如何把子圖按正確的順序？

謝謝大家提前的幫助！ 親切的問候！

根據需要定義邊緣的順序有幫助。您的版本將1 2 10 11放在同一等級中，因此它們被設置爲一個在另一個之下。

graph 
{ 
    rankdir = LR; 
    splines = line; 

    node[ style = filled, fillcolor = grey91 ]; 
    1 2 10 11; 
    b[ label = "B", fillcolor = blue ]; 
    c[ label = "C", fillcolor = yellow ]; 


    subgraph cluster_1 
    {    
     1; 2; 
    } 
    subgraph cluster_2 
    { 
     b; c; 
    } 
    subgraph cluster_3 
    { 
     color = white  
     10; 11; 
    } 

    edge[ color = blue ] 
    { 1 2 } -- b -- { 10 11 }; 
    edge[ color = yellow ] 
    { 1 2 } -- c -- { 10 11 }; 
}
