Network-graph-component Plugin query

Hi prasanthrajac0001,

I suggest you post this question in the specific plugin page so that the plugin creators can help you.

Thanks Pedro Simões. Posted the same query,

Q1. Can we get the dynamic data from external DB's and build network diagram? How to map the nodes and edges respectively for dynamic values?

Ans: Yes. When we have accurate node details and their corresponding details in DB tables, 

1. Get the node details and its edge details from DB or view (incase of separate tables for nodes and edges)
2. Create separate expressions. One for formulating dictionary of nodes and another for formulating dictionary of edges
3. Pass them to the networkGraphField

Please find the code snippet at the bottom.

{
  a!localVariables(
//Use the expression for preparing the dictionary of nodes in case of database retrieval
    local!nodes:{
      {id: 1,label: "Node 1", hidden: false},
      {id: 2,label: "Node 2", hidden: false},
      {id: 3,label: "Node 3", hidden: false},
      {id: 4,label: "Node 4", hidden: false},
      {id: 5,label: "Node 5", hidden: false},
      {id: 6,label: "Node 6", hidden: false}
    },
//Use the expression for preparing the dictionary of edges in case of database retrieval
    local!edges:{
      { from: 1, to: 2 },
      { from: 1, to: 3 },
      { from: 1, to: 4 },
      { from: 4, to: 5 },
      { from: 4, to: 6 }
    },
  networkGraphField(
    label: "Network Graph Field",
    labelPosition: "ABOVE",
    validations: {},
    height: "SHORT",
    nodes: local!nodes,
    edges: local!edges,
    nodeOptions: {},
    edgeOptions: {
      arrows: "to"
    },
    groups: {},
    layout: {
      hierarchical: {
        direction: "UD",
        sortMethod: "directed"
      }
    },
    interaction: {},
    physics: {
      barnesHut: {
        springLength: 200
      }
    },
    showBorder: true
  )
  )
}

Q2. I have a requirement, to show the drill-down level of each node as a separate interface. Is it possible to implement the same by using Network-graph-component Plugin?

Ans: No. The existing networkGraphField component does not have link facility. If we need we need to customize the component to enable the link facility.

Q3. Can we show/hide the nodes depends on the requirements? Any examples please share.

Ans: Yes. We can hide the nodes by using the hidden parameter of the Node. Following code snippet demonstrate this requirement.

Note: When we hide node, the node will be disappeared. Its associated edges will be removed from it connected nodes.

…

nodes: {{id: 1, label: "Node 1", hidden:true }}
