title: Edges with same source and target in Gephi?
body: <p>I want to draw a graph with Gephi, my nodes are countries and my edges correspond to trade exchanges between countries, but I have an additional information which is the exchanged product. If two countries trade different products, I happen to have several edges between two given nodes (the goal is to color them accordingly to the product). Weight is proportional to exchanged quantity.</p>
  
  <p>For example I have the following edges : </p>
  
  <p><code>source target  label   weight<br>
     104    0      22      0.18<br>
      64    0      22      0.18<br>
     120    0      22      0.12<br>
     120    0      31      0.09</code></p>
  
  <p>But Gephi selects one of the edge and sums the weights... </p>

  <p>If I choose id myself to make him undestand that even if I have the same source and target, I can have different edges, he still doesn't understand... </p>
  
  <p><code>id       source  target    label   weight<br>
  104_0_22    104     0        22      0.18<br>
  64_0_22      64     0        22      0.18<br>
  120_0_22    120     0        22      0.12<br>
  120_0_31    120     0        31      0.09</code>  </p>
  
  <p>I don't paste the picture but it is the same exactly..</p>
  
  <p>Do somebody know how to handle that ? </p>
