But I have some issues when it comes to the Composer installation. Network Setup: Host1: Orderer, Peer1.Org1, Peer2.Org1, CLI Host2: Peer1.Org2, Peer2.Org2 When it comes to the Fabric setup everything appears to be ok. I'm able to start the network, join the peers from the second host, and update the anchor peers (one for each organisation). The Composer installation starts with creating and importing the business network card and

I would like to know if it's possible to achieve what's shown by (B) with JGraphX. The reason for such requirement is that the graph looks clutted if there are many edges from the same source. 回答1: Using the EDGESTYLE_ELBOW is not a bad option but if you want to use the layout you can probably adapt the following. The CompactTreeLayout creates a edge of three points. If you extend the layout, you can edit the first 2 points of

Cannot add edges, Invalid vertex ID in IGraph

Please Help!!! 回答1: I think this all depends on what g has for vertices. If you start off with an empty g , you only have the vertex 0 , so if you're trying to call add_edges with two different vertices, it's just not
