节点的排名提供了未评级的结果

Question

digraph para

我试图按以下方式对节点进行排名：

   {rank=same 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40}
   {rank=same 41 42}
   {rank=same 43 44 45 46}
   {rank=same 47 48 49 50 51 52 53 54 55 56 57 58 59 60}
   {rank=same 61 62 63 64 65 66 67 68 69 70 71 72}
   {rank=same 73 74 75 76 77 78}

但是，在我看来，只有第一级分配正确（对于节点0,1,2，...，40）。您能帮我看看其他组排名的问题吗？他们为什么不彼此分开？

Answer 1

rank = same只能对列在一起的那些节点强制相同的等级，不能保证两个rank = same获得不同的等级。而且似乎您图中的层次结构与选定的子图不太匹配尝试用群集和/或节点着色替换您的排名，以分析问题所在。例如：

subgraph cluster1 {0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40}
subgraph cluster2 {41 42}
subgraph cluster3 {43 44 45 46}
subgraph cluster4 {47 48 49 50 51 52 53 54 55 56 57 58 59 60}
subgraph cluster5 {61 62 63 64 65 66 67 68 69 70 71 72}
subgraph cluster6 {73 74 75 76 77 78}
或
{0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40}
node[style=filled]
{node[fillcolor=red] 41 42}
{node[fillcolor=blue] 43 44 45 46}
{node[fillcolor=salmon] 47 48 49 50 51 52 53 54 55 56 57 58 59 60}
{node[fillcolor=pink] 61 62 63 64 65 66 67 68 69 70 71 72}
{node[fillcolor=green] 73 74 75 76 77 78}
