1. Click on a visualization on a dashboard.
The associated data table is displayed on the Data Table pane.
2. Click the Options button. The Visualization Settings pane is displayed along with the current data table being used.
3. Select another data table in the Datatable drop-down list.
The visualization is updated to reflect the data setting in the new associated data table.
