1. Changing position of edge labels when opening/closing group nodes

Question

Hi!

I have a graph with a lot of groups; many edges are departing from them, and quite often each edge has more than one label. The problem is that, when I open or close a group, the path of the edges change and the labels get displaced, sometimes very far from the corresponding edge.

Is there a way to tell yEd where the labels should be when the group is open or closed?

Could I also set the path of the edges, always depending on whether the group is open or closed?

A second question.

In my graph there are so many nodes and edges that it is difficult to understand what goes where. Could it be possible to write a simple program or give instructions so that, when I want to see all the edges of type A they get coloured, of type B, they get coloured and so on?

Thanks!

Answer 1

Hi,

I have a roughly similar problem (front, back positioning) with group nodes posted 4 h ago.

Perhaps I can give you a tip/workaround for your 2nd question:

You can use the Selection for highliting edges:

Tools->Select elements...->Edges->Select=Selected Nodes->Ok

Hi Frank,

Thanks for your suggestion! I tried the way you said and also all the other options, but unluckily it's not enough :-(  What I would need would be to add to the dropdown list the selections which I specify. I need to highlight single edges scattered all over the graphs. I don't know whether this is possible.
Thanks anyway...

Cheers,

Jacopo

Unfortunately, no.

You can try to use custom properties and the properties mapper to achieve this. E.g. create a custom edge property "Type" of type "Integer", specify for each edge its type, then create a mapping that maps each edge type to a specific line color.
