How to move non-clustered nodes in max rank

Help
1

Hi all,

I wonder if it is possible to make this graph somewhat more compact by moving the non-clustered nodes below the clusters. I tried multiple options but nothing seems to work.

Thanks in advance for the help!

The title of your request even provides the answer. Add the following to the bottom of the file:

 {rank=sink _foo _bond0 _lo  _enp1s0 }  // or rank=max

Can’t believe after all these years this was a useful feature, since it was only implemented out of a compulsive sense of completism.
