[2.0.0] Node scaling not working

[aguinaldoabbj]

Hi again, @thebestnom !

In my vis app I was trying to use the automatic scaling of vis.js by setting the "value" attribute instead of the "size" attribute.

However, if I try to map the value attribute to a property of a node it doesn't work. All the nodes stay with the same size:

The nodes in red and blue have a "inDegree" attribute in Neo4j. I can map the label though. Am I doing something wrong ?

{
  "container_id": "viz",
  "neo4j": {
    "server_url": "neo4j://1.1.1.1:7687",
    "server_user": "",
    "server_password": ""
  },
  "labels": {
    "E": {
      "value": "inDegree",
      "label": "node_id",
      "[NeoVis.NEOVIS_ADVANCED_CONFIG]": {
        "static": {
          "color": "lightblue",
          "shape": "dot",
          "font": {
            "color": "black",
            "background": "none",
            "strokeWidth": "0",
            "size": "20"
          }
        },
        "function": {
          "color": "(node) => {if (node.properties['Type'] == 'info') return 'lightblue'; else return 'tomato';}"
        }
      }
    }
  },
  "initial_cypher": "MATCH p=(:E)-[]-() RETURN p LIMIT 100"
}

This is really weird... It should just work 😅 Maybe they all have the same value? If the shape is dot which you did the value should just scale...

Yep, this is weird.

The nodes have different values for this inDegree attribute, as you can see if I access the viz object in the console:

Do you know where could I find out if the "value" attribute is indeed being mapped?

Another strange thing: if I use value approach for just one of the labels, every node configured in Neovis gets the same size, for all labels...

just tested on data from https://github.com/neo4j-contrib/neovis.js/issues/198#issuecomment-919372724 with same configuration (except the value is mapped instead of cypher) and it's just works...

[CinderD]

cypher: { value: "MATCH (n) WHERE id(n) = $id RETURN n.pagerank", label: "MATCH (n) WHERE id(n) = $id RETURN n.name" }, I tried. Both the label and the value could only be extracted from the cypher statements.

@aguinaldoabbj try moving your definition of node shape from [NeoVis.NEOVIS_ADVANCED_CONFIG].static to config.visConfig.nodes, e.g.:

{
    "container_id": "viz",
    "neo4j": {
        "server_url": "neo4j://1.1.1.1:7687",
        "server_user": "",
        "server_password": ""
    },
    visConfig: {
        nodes: {
            shape: 'dot'
        }
    },
    "labels": {
        // ...
    },
    "initial_cypher": "MATCH p=(:E)-[]-() RETURN p LIMIT 100"
}

The example that @thebestnom referenced uses that style of config. For me it also worked with the visConfig option.
