Unexpected bends in Layered Layout [message #1802223]

Hi everybody,

I'm using the LayeredLayoutProvider to lay a graph out. However, by doing so, unexpected routings are generated for edges. For instance :

This happens even though I have set the following option upon defining the root

graph.setProperty(CoreOptions.EDGE_ROUTING, EdgeRouting.ORTHOGONAL);

Are there certain options that have to be configured properly beforehand in order for these weird edges not to be generated ?

Also, when comparing the JSON generated from the graph before and after its layout, it appears that certain edges get multiplied, leading to redundancies. Is there a way to avoid this phenomenon ?

You can find attached a JSON file representing the graph illustrated before.

Thanks in advance for your precious help

Hi,
Has anyone been in such a situation where edges would have such bends, even though the CoreOptions.EDGE_ROUTING option has been set to EdgeRouting.ORTHOGONAL ?
Sorry for being pushy, and thanks in advance

Hi Baptiste,

sorry for the late reply.

Laying out your graph with the current development version in our Eclipse environment yields a correct layout (see attachment). Thus the following questions:

Are you using the Java or JavaScript versions of our libraries?
Which version are you running?

Cheers,
Chris
