如何在图表上显示边缘标签?

I am trying to load a gexf file with sigInst.parseGexf('data/test.gexf').

To create an edge with label I have this line in gexf file:

<edge label="test" id="7" source="14" target="18" type="directed"/>

but seems that sigma.js ignore this label field.

How can I show edge labels in graphs?

It's not yet possible with the main sigma.js library. However, I just forked the repository and added the capability on github.com here: https://github.com/sam2themax/sigma.js

To enable this new feature, set edgeLabels to true in your drawingProperties.
