Multiple Marriages - Genogram

GoJS

I think you’re not setting up the Nodes and Links correctly. Notice that in the Genogram sample, there’s a setupDiagram function that you call to create the appropriate Nodes and Links.

I tried the following family:

      setupDiagram(myDiagram, [
          { key: 0, n: "husband", s: "M", ux: [1, 2, 3] },
          { key: 1, n: "wife 1", s: "F" },
          { key: 2, n: "wife 2", s: "F" },
          { key: 3, n: "wife 3", s: "F" },
          { key: 11, n: "child 1 1", s: "M", f: 0, m: 1 },
          { key: 12, n: "child 1 2", s: "M", f: 0, m: 1 },
          { key: 21, n: "child 2 1", s: "F", f: 0, m: 2 },
          { key: 22, n: "child 2 2", s: "F", f: 0, m: 2 },
          { key: 31, n: "child 3 1", s: "F", f: 0, m: 3 },
          { key: 32, n: "child 3 2", s: "M", f: 0, m: 3 }
        ]);

I got back these results:

Oh, wait – there was one change I made. I set the Link.routing on the Marriage Links to be AvoidsNodes:

      myDiagram.linkTemplateMap.add("Marriage",  // for marriage relationships
        $(go.Link, { selectable: false, routing: go.Link.AvoidsNodes },
          $(go.Shape, { strokeWidth: 2, stroke: "darkgreen" })
      ));

If I move one of the parent nodes around, I can see that the relationships are maintained visually. (But a new layout is not performed.)
