Graphviz：如何在一行中制作时间线/排名

layoutgraphvizdotrank

我正在尝试创建荷兰能源行业合并的时间轴。我使用rank=same来强制节点保持在同一年份上。然而，时间轴会在自身上产生交错，导致“过去”的节点与“1993”年的节点在同一列中。
如何使年份整齐地保持在一行，并将相应的节点分别放置在不同的列中？

我发现可以通过替换以下内容来解决问题：

{ rank=min; 1993; "NUON_1993" [label="NUON"];
"EDON";
"PNEM"}

... with:

{ rank=same; 1993; "NUON_1993" [label="NUON"];
"EDON";
"PNEM_1993" [label="PNEM"]}

看起来是因为PNEM与Past的排名相同，所以在与PNEM一起使用rank=min后，将1993移回与Past相同的等级。

很好发现！我找不到那个。 - SSteve
