I have been using yEd for several years and am recently returning to it after a 6 month break. Now, when I open old graphs, I get curvy edges. No matter what layout I choose I can not get back to orthoganal edges. I have tried everything I know to do without any luck. I need help please.
I have attached a sample graph here.
Note: I this graphml file was generated using a script that has been in production for some time. This script has always generated files that allowed changes in layout using yEd. We often generate files containing 10,000 or more nodes and regularly view these using an orthogonal edge layout. After a brief pause in usage (6 months) the graphml files generated by this script can not be viewed with orthogonal edges.
