Power BI - Custom Tooltip in Power BI

Steps to Create a Custom Tooltip

1. Create a Tooltip Page

• Add a new page in Power BI.
• In Page Information, turn on Tooltip.
• Rename it (e.g., Sales Tooltip).
• Design this page with visuals you want to show when hovering (tables, charts, KPIs).

---

2. Design the Tooltip

• Example visuals:
  • A mini line chart showing sales trend for the selected region.
  • A card showing total sales.
  • A bar chart showing top 3 sales reps.

---

3. Assign Tooltip to a Visual

• Go back to your main report page.
• Select a visual (e.g., bar chart of sales by region).
• In Visualizations → Tooltip → Type, choose Report Page.
• Select your custom tooltip page (Sales Tooltip).

---

4. Test the Tooltip

• Hover over a bar (e.g., South Region).
• The custom tooltip page appears, filtered for that region.

 Example with Sample Data

Main Report (Sales by Region)

Region	Total Sales
North	9000
South	16000
East	6000
West	8000

Custom Tooltip Page (when hovering over South)

• Card: Total Sales = 16,000
• Line Chart: Monthly sales trend for South
• Bar Chart: Top Sales Rep = bob@company.com

 Key Notes

• Tooltips can include any visuals (cards, charts, tables).
• They automatically filter based on the data point hovered.
• You can create different tooltip pages for different visuals.
• Works great with Drillthrough and RLS to give secure, contextual insights.
