Gephi API - Edge to self, Two edges between same nodes

[Junkers]

Hello,
this is my first post so I want to thank You guys for great tool
I use Gephi with my recommendation system graph virtualization software. For test I use MovieLens dataset.
There are 3 issues i can't solve:
1. I have to create edges like on figures 1 and 2 on image below (self-edge and multiple edges between nodes).
is this topic still current? http://forum.gephi.org/viewtopic.php?f= ... edge#p9515

2. I add random color to my edges with method like

Code: Select all

Edge temp;    
Random rand = new Random();
                r = rand.nextFloat() % 1.0f;
                g = rand.nextFloat() % 1.0f;
                b = rand.nextFloat() % 1.0f;
temp.getEdgeData().setColor(r, g, b);
edges.add(temp);

But in visualization they are greyed out:

3. This graph above is autoconfigured can i create button to relocate nodes and edges?

Thanks for all help

On #1 - for now, Gephi doesn't support multiple edges between nodes. I need to think about the other questions before responding.
