More than 7 solid line types possible?

Question

I would like to show an Interface Diagram (EAI Middleware), with Sender- and Receiver Systems.

The arrow width should indicate the number of messages that have been sent. But it turns out, that this doesn't scale, as Yed "only" has 7 solid line styles. It would be nice, to have a line width taht scales. Something like the blue thick arrow in the picture below. Is this already possible?

 

Answer 1

Your observation is to the point, yEd provides 7 discrete line widths, i.e., the thick blue arrow seen in the diagram isn't possible.
