single visual - dual tooltip(default & Report page)

In Power BI, a single visual cannot show both the Report-page tooltip and the default (built-in) tooltip at the same time.
Power BI allows only one tooltip type per visual — either:

1.Default Tooltip (auto-generated by Power BI).

2. Custom / Report Page Tooltip

Once a Report Page is assigned.

You can do two things:

ONE:

Add the default tooltip fields manually into your report-page tooltip

You can re-create the default tooltip by manually adding:

• Axis value

• Legend

• Data point value

• Additional fields

This gives the same effect as the default tooltip while keeping your custom layout.

TWO:

Use Power BI “Smart Tooltip” patterns

You can build a toggle inside your tooltip page:

Example:

• Button: Show Default Tooltip

• Button: Show Custom Tooltip

Use bookmarks to flip between two tooltip layouts.

This is the closest to “dual tooltip” behavior.
