Creating Multiple Link form single Node

how can i get multiple link from single node in different Ports.
Here as shown in given image I am not able to link multiple link from different port in single node
So can you tell me how it is possible to link different link from different ports

For this i am using this code

For creating Node
myDiagram.nodeTemplateMap.add("", // the default category
(go.Node, "Spot", nodeStyle(), // the main object is a Panel that surrounds a TextBlock with a rectangular Shape (go.Panel, “Auto”,
(go.Shape, "Rectangle", { fill: "#00A9C9", stroke: null }, new go.Binding("figure", "figure")), (go.TextBlock,
font: “bold 11pt Helvetica, Arial, sans-serif”,
stroke: lightText,
margin: 8,
maxSize: new go.Size(160, NaN),
wrap: go.TextBlock.WrapFit,
editable: true
new go.Binding(“text”).makeTwoWay())
// four named ports, one on each side:
makePort(“T”, go.Spot.Top, true, true),
makePort(“L”, go.Spot.Left, true, true),
makePort(“R”, go.Spot.Right, true, true),
makePort(“B”, go.Spot.Bottom, true, true)

For creating link :
var linkSelectionAdornmentTemplate =
(go.Adornment, "Link", (go.Shape,
// isPanelMain declares that this Shape shares the Link.geometry
{ isPanelMain: true, fill: null, stroke: “deepskyblue”, strokeWidth: 0 }) // use selection object’s strokeWidth

myDiagram.linkTemplate =
  $(MultiArrowLink,  // subclass of Link, defined below
        relinkableFrom: true,
        relinkableTo: true,
        reshapable: true,
        resegmentable: true
      { isPanelMain: true },
      new go.Binding("fill", "color"))
    // no arrowhead is defined here -- they are hard-coded in MultiArrowLink.makeGeometry

Are you using a GraphLinksModel and have you set the properties on it to make use of multiple ports? GraphLinksModel | GoJS API and GraphLinksModel | GoJS API
