如何在此图中排序节点位置？

Question

我有以下图表Link

最后一行无法对齐。我已经尝试添加虚拟节点，但它似乎不起作用。

您可以使用rank=same 将节点显式约束到同一等级：

digraph G {
dir="back";
{
  rank=same;
  edge[style=invis];
  f30->f31->f32->f33->f34->f35->f36;
}
{
  rank=same;
  edge[style=invis];
  f40->f41->f42->f43->f44->f45->f46->f47->f48->f49->f410;
}

{
  rank=same;
  edge[style=invis];
  f50->f51->f52->f53->f54->f55->f56->f57->f58->f59->f510->f511->f512;
}

f00 -> f10[dir="back"];
f00 -> f11[dir="back"];
f10 -> f20[dir="back"];
f11 -> f22[style=invis];
f10 -> f21[style=invis];
f10 -> f22[dir="back", constraint=false];
f11 -> f21[dir="back", constraint=false];
f11 -> f23[dir="back"];


f20 -> f30[dir="back"];
f20 -> f31[style=invis];
f20 -> f32[dir=back, constraint=false]
f21 -> f31[dir=back, constraint=false];
f21 -> f32[style=invis];
f21 -> f33[dir="back"]

f40 -> f50[dir="back"];
