Tooltips in Power BI

Tooltips in Power BI provide additional contextual information when a user hovers over a visual element, such as a bar in a chart or a data point in a scatter plot. They enhance interactivity and help users understand the underlying data without cluttering the main report.

Types of Tooltips in Power BI 1. Default Tooltips – Automatically generated by Power BI for visual elements.
2. Report Page Tooltips – Custom tooltips designed using separate report pages.
3. Dynamic Tooltips – Tooltips that display dynamic content based on measures.
4. Modern Visual Tooltips – Available in some visuals for advanced formatting.

Default Tooltips Power BI automatically creates tooltips displaying data for the hovered visual element. These include values from the visual’s fields, like axis categories, values, and legends.

How to Customize Default Tooltips Step 1: Select the visual.
Step 2: Go to the Format pane and expand the Tooltip section.

We can modify the text and background colour and its formatting.

After changing the background colour, see its effect on the tooltip by hovering it on the data point.

Step 3: The default tooltip can be customized by adding fields to the Tooltips field well. We can add multiple fields in the Tooltips.
