问题 I would like to generate static graph use GraphStream. Is there any suggestion solutions? I read input data from DGS file (generated from other model). Because the number of nodes is not fix every time and I don't want to manually specify each position of each node. Currently I can use the autolayout function to place the nodes and the result is OK, but the problem is: each node can be moved if you click the node and drag it. Is there any way to generate the graph use autolayout, and the node

问题 It is possible to activate layout process in GraphStream with Viewer#enableAutoLayout(). Unfortunately, this process will tamper each user interaction like node dragging.

Displaying Parallel Edges in Graphstream

阅读更多关于 Displaying Parallel Edges in Graphstream

I have a multigraph, and I would like to be able to see each edge that goes from one vertex to another clearly. For example, when I have a graph with 2 vertices, and 2 edges going from the first to the second, I would like to see 2 arrows going from the first node to the second, instead of the arrows overlapping. This is my code currently, and you can see that I'm trying to have 2 edges connecting A and B: import org.graphstream.graph.*; import org.graphstream.graph.implementations.*; import org.graphstream.ui.swingViewer.Viewer; public class Tutorial1 { public static void main(String args[])
