You can define several breakdowns for a visualization.
1. Under the Breakdown tab, click New Breakdown .
A new Empty breakdown definition is added under the Breakdown tab with the View icon turned on. The visualization also shows a single bar.
2. To add more breakdown levels, drag text columns to the Items pill or drop area.
After dragging a data column to a breakdown, this will break apart the aggregated data into separate bars and the column is added under the Items drop area of the Breakdown tab and Breakdown section of the visualization. Also, the dragged column will replace the Empty state name.
You can have as many levels in the breakdown as you like, although best practice is to limit the hierarchy to five or fewer levels.
3. Click the Save icon on the toolbar.
When saved, the notification is displayed.
