More & more correct info about getting the rank of nodes:

  • sometimes the rank value changes between phases 1, 2 and 3. So to get the final ranking, run dot -Gphase=3.
  • normally, dot -Gphase=3 will add a rank attribute to the output, but dot -Gphase=4 or dot -Gphase="" or plain old dot ... will NOT show the rank attribute
  • however, dot will keep any rank attribute it is given as input, so you can run this pipeline that saves the rank as a final attribute: dot -Gphase=3 myfile.gv | dot -Gphase="" >myfile.dot (note the phase=“” to reset the phase attribute set in the first dot invocation)
