Hey there,
I have a list of labels which I'd like to attach to the rendering of a
graph. I can get a PDF with labels on the edges using:
import graph_tool.all as gt
[[[make graph g with vertices and edges]]]
gt.graphviz_draw(g, eprops={"label":g.edge_index},output="out.pdf")
#produces a graph with edges labeled 0 to n-1
gt.graphviz_draw(g, eprops={"label":"test label"},output="out.pdf")
#produces a graph with all edges labeled "test label", so labeling with
strings is possible
What I'd like to do is to use those edge_index values as index for an arary
containing my labels as strings to be placed in the graph.
eprops={"label":labelStrings[i]} # where i is equal to the numeric value of
the edge_index
How would I do that?
edge_index is a PropertyMap so that can't be used as index, but getting the
values out as an array fails too so apparently it is of type vector or
object.
Perhaps if I could see what a 'vector' is as defined here I might be able to
figure it out, but it's not specified:
http://projects.skewed.de/graph-tool/doc/graph_tool.html#graph_tool.PropertyMap
Being able to assign a label at the moment the edge is created with add_egde
would work too and is even preferable in my situation, so that might be a
solution too if I'd know how.
Thanks,
Jelle
