Supplying data for multiple layers

Charts on charts allows you to include different sources and display it in different ways - all in a single chart. All the charts of the multiple layers can have their own respective data sources, so when creating a chart you can pass the data as an array.

In order to reference one of the layers from a chart that will utilize it's data, you can specify ID's for your layers in the following manner:

    var options = {
      data: [
        {id: "foo", url: "/path/to/foo.json"},
        {id: "bar", url: "/path/to/bar.json"}
      ]
      /* ... */
    };

Referencing the data for a layer

When specifying layers, data can be referenced by specifying the layer id:

    var options = {
      /* ... */
      layers: [
        {
          type: "shapes",
          data: {id: "foo"},
          /* ... */
        },
        {
          type: "items",
          data: {id: "bar"},
          /* ... */
        }
      ]
    };
