Edge merging points and edge crossing points [message #1753839]

Hello,

in huge diagrams with edge merging layout configuration, it's hard to understand to which direction an edge is going. For this problem i had the idea to add arrows on points where one edge merges into another edge.

Another problem which i noticed is, that you can't differ an edge crossing from an edge merging if you have multiple edges in an area (maybe not good recognizeable). For this i had the idea to use edge crossing visualization like in a circuit diagram.
Example: index.php/fa/28406/0/

Is it possible to gather the layouting information of an edge (at least merging points)? Thank you in advance.

Best regards
Mehmet Karaman

If you use the elk.layered algorithm, after layout the edges should be annotated with junction points.

This is nothing the layout algorithm would do. You may be able to add it in your rendering framework based on edge directions and the above mentioned junction points.

Thank you for the answer. This seems to be the thing what i am looking for.
