You can add pivot tables in the Visualization view to display data from an existing (input or output) table aggregated in different ways.
To show data aggregated, select the table columns and rows that you want to display and select the appropriate aggregator to compute the data for each cell.
For example, the JSON code that is generated for a pivot table is as follows:
{
"name": "",
"type": "Pivot",
"props": {
"container": "Pivot2",
"data": "party",
"spec": {
"config": {},
"columns": [
{
"property": "Party Size",
"label": "Party Size",
"type": "Number",
"visible": true,
"width": 0,
"style": {}
}
],
"rows": [
{
"property": "Payer Gender",
"label": "Payer Gender",
"type": "String",
"visible": true,
"width": 0,
"style": {}
},
{
"property": "Day of Week",
"label": "Day of Week",
"type": "String",
"visible": true,
"width": 0,
"style": {}
}
],
"tableRenderer": "Table Row Heatmap",
"aggregator": "Count Unique Values",
"aggregatedCol1": "Tip"
},
"search": ""
}
}
