Guidance on Auto-Layout w/ Semantics [message #1849931]

I need a layout algorithm to consider node types. Using the picture attached as an example. I'd like the nodes of the same color to be grouped together in the same column/layer.

I was looking at ELK layered and it seems to do something similar. I'm wondering whether its possible to modify one of the layering options in https://github.com/eclipse/elk/tree/master/plugins/org.eclipse.elk.alg.layered/src/org/eclipse/elk/alg/layered/p2layers so that it could group the nodes by type.

Hi, generally it is possible to group nodes in layers given the fact that no in-layer edges exist.
See an example here

The solution is a mixture of cycle breaking and layer assignment.

With the next release it will also be possible to do cycle breaking based on the order of the nodes in model.

Hi,

you could also have a look at layout partitions, as in this example
