    Methods Description

    data

    data()

    Getter for the data.

    Returns:

    Object - Return data object with nodes and edges fields
    See listing
    var data = chart.data();
var nodesData = data.nodes;
var edgesData = data.edges;
edgesData.set(0, 'stroke', '1 blue'); //Set edge stroke for first edge in dataset
nodesData.set(0, 'shape', 'star5'); //Set shape for first node in dataset

    Try it:

    data(data)

    Setter for the data. Learn more about data

    Params:

    NameTypeDescription
    dataObjectData is object with two required fields 'edges' and 'nodes'.
    1. nodes is one of
      • Array where each element is object
      • anychart.data.View
      • anychart.data.Set
    2. edges is one of
      • Array where each element is object
      • anychart.data.View
      • anychart.data.Set

    Requires for node data object:
    • Data object must contain required 'id' field.
    • For fixed layout data must contain 'x' and 'y' fields otherwise it will be placed at (0:0) coordinate.
    • Define group field, if you want group nodes, nodes of same group must has equal group id
    Requires for edge data object:
    • edge object must contain required 'from' and 'to' fields, this fields is ids of nodes that mean nodes dataset must contain nodes with this ids
    • id field is not required but if you want have access to it you need pass it too
    You can pass with data all settings you can setup though methods of this element, fill, stoke and etc.
