graphviz:强制节点在rankdir = LR中排在最前面 [英] graphviz: force nodes to top in rankdir=LR

问题描述

我想在图表的顶部显示开始中间结束"标签

I want to have the 'start middle end' label appear at the top of my graph

但是无论我把代码放在哪里，它似乎都默认为最底端.有可能吗?

But it seems to default to the bottom no matter where I put the code. Is it possible?

digraph G {
  rankdir=LR;

{node [shape=plaintext, fontsize=16];
"Start"->"Middle"->"End"[style=invis];
}

node [shape=box];
{ rank=same
"Start";a;
}
{ rank=same
"Middle";b;d;
}
{ rank=same
"End";c;e;
}

"a"->"b"->"c";
"d"->"e";

}

推荐答案

这对我有用.

digraph G {
  rankdir=LR;
  {
    node [shape=box];
    blank [style=invisible]
    blank -> d [style=invisible dir=none]
    "a"->"b"->"c";
    "d"->"e";
  }
  {
    node [shape=plaintext, fontsize=16];
    "Start"->"Middle"->"End"[style=invisible dir=none];
  }
}
