GraphX For .Net Two DataEdges from one DataVertex to another

Question

I'm using GraphX for .Net library to build graph based on my data. I have relations: obj1->obj2 (type1), obj2->obj3(type1), obj1->obj2(type2) (type1 and type2 is a type of line, which connects two objects). I'm adding DataVertex this way:

var dataVertex = new DataVertex(obj1.Name);
dataGraph.AddVertex(dataVertex);

Then I'm adding DataEdges:

var dataEdge = new DataEdge(obj1, obj2) { Text = "type1" };
dataGraph.AddEdge(dataEdge);
dataEdge = new DataEdge(obj2, obj3) { Text = "type1" };
dataGraph.AddEdge(dataEdge);
dataEdge = new DataEdge(obj1, obj2) { Text = "type2" };
dataGraph.AddEdge(dataEdge);

But when graph is generated (I'm using BidirectionalGraph) I see only one relation between obj1 and obj2. What should I add to code to see both relations in generated graph? I need to see both relations and labels because they represent cables between two physical objects. I suspect what two relations just overlay one each-other.
If I set allowParallelEdges to false, I see only first relation, if true then only second relation.

I think you are close. Try setting the ParallelEdgeDistance to some value. For example:

            logicCore.EnableParallelEdges = true;
            logicCore.ParallelEdgeDistance = 25;
