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?
