vq.utils.GoogleDSUtils.dataTableToNetworkArray(googleDataTable)
Converts a special DataTable object into a network object used by CircVis.
For a DataTable with fields: chr1, start1, end1, value1, options1, chr2, start2, end2, value2, options2, linkValue
the function returns an array of JSON objects consisting of two node JSON objects and a linkValue:
{node1,node2,linkValue}
The JSON array can then be passed into the NETWORK.DATA.data_array parameter used to configure Circvis.
- Parameters:
- googleDataTable
- - google.visualizations.DataTable object returned by a google datasource query
- Returns:
- network_json_array - a JSON array representation of a Google Visualizations DataTable object. The column label is assigned as the property label
