cytoscape: Dagre-layout prevent nodes from laying on edges

I am using cytoscapejs with dagre layout (https://github.com/cytoscape/cytoscape.js-dagre). I am very happy with this extension, however, there is one problem I am struggling with. In particular, I would like to prevent that nodes are allowed to lay over edges. Because of that, there are some examples where one cannot distinguish between an edge from a node to a successor and an edge from the successor of the particular node to the succeeding node. There is also an open issue regarding this misbehavior (https://github.com/cytoscape/cytoscape.js/issues/1078)

I allready tried out other curve-style layouts such as 'segments' and 'haystack' but unfortunately without success.

Does anyone of you have an idea how to do that?

Thanks in advance

Andy

You'd have to convert the points that Dagre gives you into segment values. You could put those values in .scratch() to be used in a mapper.

See https://github.com/cytoscape/cytoscape.js-dagre/issues/5

There are a lot of things in the queue for Cytoscape and the extensions, but unfortunately time and resources are constrained and this feature request is relatively low priority. You're welcome to make a pull request on the extension if you'd like to use the feature.

Thanks
