graphviz：“相同”分组框周围的虚线框

Question

我有很多盒子放在这样的水平上： 通过多条{rank=same a3 b3_1 b3_2 c3_1 c3_2 d3_1 d3_2};行，而我用a3 [label = "Assigned"];行定义元素。

我想在同一级别上的所有元素周围放置一个（点状，如果可能的话）框，例如（通过编辑器进行模型化）：

整个来源如下：

digraph customer {
layout=dot
label = "some diagram";
labelloc = "t"; // place the label at the top
node [shape=record];

{rank=same a1 b1 c1 d1};
{rank=same a2 b2 c2 d2};
{rank=same a3 b3_1 b3_2 c3_1 c3_2 d3_1 d3_2};

由于某种原因，它与rank=same声明冲突。

尝试删除它，并在其中使用rank=same来代替群集，如下所示：

subgraph cluster_one {
  label="cluster one";
  rank=same;
  style=dotted;
  a1 b1 c1 d1
};

subgraph cluster_two {
  label="cluster two";
  rank=same;
  style=dotted;
  a2 b2 c2 d2
};

或更短（一行）：

subgraph cluster_one { label="cluster one" rank=same style=dotted a1 b1 c1 d1 }

请记住，子图的宽度将与以前不同。
