Clusters #123

Closed AmanGotchu closed 5 years ago

AmanGotchu commented 5 years ago

Is it possible to assign a group of nodes with their own set of edges in a cluster without defining "cluster specific" edges?

How are clusters used in this library?

nidi3 commented 5 years ago

Can you give an example of what you want do achieve? Can you do this with the native dot implementation or would it not be possible?

Yep, its possible with native DOT -> Graphviz implementation. Just not sure if this library has support for it.

nidi3 commented 5 years ago

Just use .cluser():

Graph g = graph().with(
    graph("1").cluster().graphAttr().with(Label.of("#1")).with(node("a0").link("a1")),
    graph("2").cluster().graphAttr().with(Label.of("#2")).with(node("b0").link("b1")),
    node("start").link("a0", "b0"));

Is this possible with MutableGraphs?

.setCluster()

AmanGotchu commented 5 years ago

I'm able to create clusters and add them to my overall graph, but I can't find a way to set the rank of specific clusters inside the overall graph so only some (potentially all) start at the same spot.

How would you do it in DOT?

Do you mean like swim lanes?

AmanGotchu commented 5 years ago

Swim lanes are similar to what I want. I ended up figuring it out though! I had to make all edges that connect different clusters "constraint"="false"

So, closing the issue.
