Force specific type of node alignment

Help
1

Hi!
In my graph Graphviz aligns nodes in ranks no matter the shape. Is there a way I can influence it, so that nodes with shape=point and shape=diamond (representing bindings) are not forced in the same rank as nodes with shape=box (representing activities)? For example, below you can see that the diamond with label 6 is aligned with activity ‘Load to Vehicle’. It would be better to align it with the other bindings with shape=point and labels 5,4,2, at the place where I have drawn a star.
An observation, I am avoiding using invisible edges because they caused me problems early. I know Graphviz works best without forcing it, so I am looking for an attribute that could help solve this.
Thanks for your support in advance!

If you add the following to the graph, it will force all four nodes into the same rank.

{  rank=same
 o_7 o_11 o_22 i_6
}

p.s. a few other comments:

  • several of the nodes are defined more than once (e.g. “Reschedule Container” and Depart). This is legal but confusing
  • Units (inches) will be ignored: height=“0.2in”
  • penwidth = None will be ignored
  • shape = box is applied to a cluster but will be ignored
  • It would be safer to set minlen to an integer instead of a floating point number. minlen=4.0 seems to work, but minlen=4 would be safer.
