Display text on sides of a node

GoJS
1

How I can display text on sides on a node? Let say I want to display text on right side of a node. The node is part of a group.

I want it to be like this.

nodetext

In node Array I have node like this.

{ key: “port2”, txt:“Node1”, group: “card1”},
{ key: “port3”, txt:“Node1”, group: “card1”},
{ key: “port4”, txt:“Node1”, group: “card1”},
{ key: “port5”, txt:“Node1”, group: “card1”},

You can use a Horizontal panel. I suggest reading the intro page on panels here, as well as any other intro pages relevant to the application you’re building.

I am focusing on groups and nodes only for my diagram. I am aware of Panels and stacked node. My current implementation is based on stacked node.

On stacked node Can I put condition like

case 1: if true then show-> TextBox—Image($(go.Node, “Horizontal”)

case 2: if true then show-> Image—TextBox($(go.Node, “Horizontal”)

case 3: if true then show-> TextBox
Image

($(go.Node, “Vertical”)

case 4: if true then show-> Image
TextBox

($(go.Node, “Vertical”)

These four cases Can I put as a condition in node template(case will come from NodeDataArray)?

I think you and Hardy is talking about same stacked content on node. I am using stackedcontent but I have use cases which I have mentioned in earlier reply.

I want to make these cases to work with nodeDataarray.

Thanks

Please note that with the data that you gave before:

{ key: “port2”, txt:“Node1”, group: “card1”},
{ key: “port3”, txt:“Node1”, group: “card1”},
{ key: “port4”, txt:“Node1”, group: “card1”},
{ key: “port5”, txt:“Node1”, group: “card1”},

it’s impossible to tell the nodes apart, other than by looking at the key value. So you’ll need to have a reliable way to tell the cases apart. For now, I’ll just add a single property named “case”, but you could add two properties or more. The secret is in making sure you have the right Bindings with the right conversion functions.

  function init() {
    var $ = go.GraphObject.make;

    myDiagram =
      $(go.Diagram, "myDiagramDiv",
          {
            initialContentAlignment: go.Spot.Center  // for v1.*
          });

    myDiagram.nodeTemplate =
      $(go.Node, "Horizontal",
        new go.Binding("type", "case", function(c) { return (c <= 2) ? go.Panel.Horizontal : go.Panel.Vertical; }),
        new go.Binding("isOpposite", "case", function(c) { return (c === 1 || c === 3); }),
        $(go.Shape,
          { fill: "white", width: 24, height: 24, portId: "" },
          new go.Binding("fill", "color")),
        $(go.TextBlock,
          { margin: 4 },
          new go.Binding("text"))
      );

    myDiagram.model = new go.GraphLinksModel(
    [
      { key: 1, text: "Alpha", color: "lightblue", case: 1 },
      { key: 2, text: "Beta", color: "orange", case: 2 },
      { key: 3, text: "Gamma", color: "lightgreen", case: 3 },
      { key: 4, text: "Delta", color: "pink", case: 4 }
    ],
    [
      { from: 1, to: 2 },
      { from: 1, to: 3 },
      { from: 2, to: 2 },
      { from: 3, to: 4 },
      { from: 4, to: 1 }
    ]);
  }

produces:
