displaying parallel edges

Oct 12, 2009 at 4:43 PM

I'm developing an application using graph#.

I would like to visualize the graph below.

All works fine except the last edge: 6to6: I can't understand how to show that! 

Can someone post a short example on how to do this?

Thanks a lot.

I am in trouble whene think about an edge that start from one vertex and end on the same vertex.

Actually is impossible to reach this kind of drawing.

Are you seure I exposed your correct problem?

Yes, this is the problem.

I sent an e-mail to palinkas about it and he suggested me to create a new edge routing, but this doesn't solve my problem.

I have created an edge routing inspired to the one proposed about Sugiyama (Orthogonal).

Unfortunately it is not what I need. 

What I really need is the one that an edge starts from and ends to the same vertex and when I move this vertex, the loop-edge, follows the vertex in matter. 

I would like to show this problem using images but unfortunately I can't post them in this forum.

I would like also to know where the edges are drawn so I can draw them by a routing made by my self.

The Edge style is implemented into the Generic.xaml file inside the GraphSharp.Controls project.
