I create a graph with edge attributions (say r
, such as, r=23
).
How do display edge labels only with the values, 23
instead of {'r':'23'}
.
Related source codes are below:
# build a graph
G.add_edge(u, v, r=value)
# plot the graph
pos = nx.spring_layout(G, scale=2)
nx.draw(G, pos)
edge_labels = nx.get_edge_attributes(G,'r')
nx.draw_networkx_edge_labels(G, pos, labels = edge_labels)
plt.savefig(out_file)
The command draw_networkx_edge_labels
needs the argument edge_labels
rather than labels
.
So you need to change nx.draw_networkx_edge_labels(G, pos, labels = edge_labels)
to nx.draw_networkx_edge_labels(G, pos, edge_labels = edge_labels)
