Graphviz节点排序

Question

我希望有一个图表，其布局如下：

但是当我写下这样的代码时：

digraph g {
a->b->c;
{rank=same;b,d,e,f,g,h}
d->g [weight = 1];
d->f [weight = 10];
}

就是这样：

点指南甚至建议：

    Edge weights also play a role when nodes are constrained to the same rank. 
    Edges with non-zero weight between these nodes are aimed across the rank 
in the samedirection (left-to-right, or top-to-bottom in a rotated drawing) as far
 as possible. This fact may be exploited to adjust node ordering by placing
 invisible edges (style="invis") where needed.

我徘徊为什么它不起作用？

Answer 1

在图表中添加以下行：

f->g[style=invis];
