This setting allows you to choose which tooltip type is used for your combo visual. You can choose between two options:

• Custom Tooltip: use the tooltip style that is developed by ZoomCharts specifically for Drill Down Visuals.
• Power BI Tooltip: use the Power BI native tooltip style. Note: formatting options for the default Power BI tooltip can be located at Visualization Pane -> Format Visual -> General -> Tooltips.

If you wish to create Report page tooltips, you must choose the Power BI Tooltip option.
