I am displaying graphs with graphviz_draw

To obtain a different color for every type of vertex I use argument

vcolor=g.vp["typev"]

where the vertex property "typev" is of type int, it works just fine

My problem is with edge colors: I have an edge property called g.ep["typee"] but it is of type vector<short>, in fact it is a list of three elements and it is the second one that I need to define the color of every edge.

ecolor=g.ep["typee"][1]

and it didn't worked (this was predictable since one has to apply g.ep["typee"] to an edge first and then take the second element to get an integer). I also tried

ecolor=lambda x: g.ep["typee"][x][1]

ecolor=(lambda x: g.ep["typee"][x][1])

none of them worked. How can I obtain what I need?
