Can I make a scalable edge or arc?

0 votes
Hi Thomas,

Thanks for the reply, I've created the SVG file.

Is there a way I can use my edge/arc in the same way as the built in edges?

My arrow is a fixed length and although I can adjust the size, it would be much easier if I could just click on the first node and then the second?

Is this possible?

Thanks,

Brian

The size of arrows in yEd is not related to nodes in any way. (The size of the built-in arrows is affected by the edge line type thickness. However, this type of automatic size scaling cannot be reproduced with the  label icon workaround I described in my previous answer.)

That said, I get the feeling that we might mean different things when talking about edges/arcs and arrows.
To me, an edge is the connection between two nodes:

An arrow is a visual decoration at the endpoints of edges:


Now, what I was suggesting in my previous mail is creating a normal edge and adding a label with an icon:

Corresponding GraphML. (Note, this edge has not arrows in the technical sense.)

 

If you are actually asking how to re-use this edge style without having to go through the trouble of each time creating a label with an icon, then the answer is creating a user-defined palette section (see "Edit" -> "Manager Palette"), adding the edge to said palette (right-click the edge to open its context menu and choose "Add to Palette"), and finally double-clicking the new edge style template in the new palette section to set the style as the default edge style.
