Orthogonal Bus Routing in ELK Layered - how? [message #1734516]

Hey there, first off, thanks for you great ELK project.

I'm trying to realize a genealogy editor in the medical domain, re-enacting the way domain experts visualize and edit such graphs.

To this end, I need to realize an orthogonal bus layout routing, which should look like in the following image:

Could somebody give me some hints on how to realize this? I found the ELK layered algorithm quite promissing.

If this algorithm is the way to go, are there any hints I can deliver to the algorithm for node placement and or routing that are not covered via the properties?

Is bus routing supported at all?

Yes, ELK Layered should be able to do what you're looking for. For that kind of bus routing try to activate the "Merge Edges" option (visible in the Layout view after activating the advanced options in the toggle button of the view toolbar).

All configuration parameters of the algorithm are controllable via the properties. Apart from the layout view, they can be set programmatically. There's not much documentation on this yet, since large parts of the API have been rebuilt, but some is available here: https://github.com/eclipse/elk/wiki/Advanced-Configuration
