I have a number of (directed) graphs based on social groups, where the members have expresed likes and dislikes in respect to the other members. tkgraph makes it simple to draw the graphs in a very pleasing way, but I would like to differentiate between positive and negative relations in the graph by having the edges for the negative relations dashed and the positive ones continuous.

Is that possible? If so how?

Tom
