Hello to everyone!
I would like to know how I can properly retrieve the coordinates information of an edge, to reconstruct the path connecting two nodes. I saw that in the yEd graphml file of the network I can recognise the source and target ports (sx, sy, tx, ty) and other additional points in the <yPath> tag, which I guess represent the turns/corners of the path (imagine an orthogonal layout). The information related to the source and target ports seem however to be positioned relative to a system having the origin in the centre of the corresponding source/target nodes. Do you think I have correctly understood the structure and meaning of the tag? Thank you in advance!
