Help： after graph initialization, how to update graph configuration

[chi-gao]

I have registered two custom edges, and I want to change the default edge type after some event. I can't find any api to do this, please help me.

I have tried graph.get('cfg') but it's result is undefine, so I can't achieve this by graph.set('cfg', xxxx).

sorry, please ignore me.
graph.get(xx) and graph.set(xx) can be used to update graph configuration directly. so the answer is just use graph.get('defaultEdge') and graph.set('defaultEdge', xxxx).

And another way is to change every edge configration and then call graph.render to refresh the canvas.
