Problem with neighborhoods plugin and loading graph

Hello, I have problem with loading my graph exported to json from gephi into neighborhoods plugin. Arctic.json example works fine but when i change file at db.load line i get blank canvas without an errors in console. I can’t figure out what is wrong with my file, when i use parser it works fine. xtest2.zip I have another problem … how to iterate on edges, nodes using event listeners ? In old version of sigma there was code that allowed to hover all neighbours of node when mouse point(iterEdges,e.content) , but now these methods were removed 😦

`var g = {
nodes: [],
edges: []
};
var s = new sigma({

  graph: g,
  renderer: {
    container: document.getElementById('graph-container'),
    type: 'canvas'
  },
  settings: {
    doubleClickEnabled: false,
    enableEdgeHovering: true,
    edgeHoverColor: 'edge',
    defaultEdgeHoverColor: '#000',
    edgeHoverSizeRatio: 1,
    edgeHoverExtremities: true,
  }
});
sigma.parsers.json('data/xdtest2.json', 
  s,
  function() {
    s.refresh();
  }
);

I tried s.g.edges.length s.graph.edges.length but i dont know where nodes and edges are stored. Last problem i encountered is when i tried use sigma.plugins.relativeSize(s,1); after parser, the graph had not changed … Thank you.

Hello Everyone, this worked for me:

sigma.classes.graph.addMethod('neighbors', function(nodeId) {
        var i,
            neighbors = {},
            index = this.allNeighborsIndex.get(nodeId).keyList() || {};
            for (i = 0; i < index.length; i++) {
                neighbors[index[i]] = this.nodesIndex.get(index[i]);
            }
        return neighbors;
});

Hi for the neighbours problem use this function:

sigma.classes.graph.addMethod('neighbors', function(nodeId) {
    var k,
        neighbors = {},
        index = this.allNeighborsIndex[nodeId] || {};

    for (k in index) {
        neighbors[k] = this.nodesIndex[k];
    }
    return neighbors;
});
