How to display parallel edges in a directed graph

Hi,

I was just wondering how to display the edges as parallel edges. I am asking this because i want to use nodexl to model a directed multigraph. Evertime I use reciprocal edges it appears as 1 edge with arrows pointing both ways like this <------>. I would like the edges to be treaated seperately. 

Thank you

I'm afraid that NodeXL can't do that yet -- it always draws parallel edges on top of each other.  We're talking about adding a more sophisticated edge-routing algorithm, but we haven't gotten to it yet.

You might try experimenting with varying the width and opacity of one of the edges to make the two edges distinct.  For example, if you set the width and opacity of one of the edges to 3.0 and 30, respectively, you will be able to see both edges.
