graphviz with combined edges -


i'm looking way achieve in graphviz:

          --- node b            | node ---           |           --- node c

another example (at bottom): http://machining.grundfos.de/media/60727/grundfos_pumpenhandbuch.pdf#23

is there way of doing graphviz?

so far got orthogonal edges:

digraph g {  graph [rankdir=lr,splines=ortho,concentrate=true];  node [shape=box,];  edge [dir=none];   -> b;  -> c; }

you must introduce intermediate (eventually hidden) nodes act split points. instance:

digraph g {  graph [rankdir=lr,splines=ortho,concentrate=true];  node [shape=box,];  edge [dir=none];  [shape=point];  -> -> b;  -> -> c; }

yields
