Testing Focus Mode

Focus mode is a critical feature in Power BI that expands a single visual for detailed analysis. Testing your theme in focus mode ensures it looks great in all viewing contexts.

How to Test Focus Mode:

  1. 1

    Hover over any visual in the preview

  2. 2

    Click the focus icon (arrows) that appears in the top-right corner

  3. 3

    Visual expands to fill the preview area

  4. 4

    Test your theme's appearance in this expanded view

  5. 5

    Click outside the visual or the X button to exit focus mode

Visual Selection Synchronization

One of Power UI's smartest features is the automatic synchronization between the preview and the Visual Styles panel.

How Sync Works:

1

Click any visual in the preview panel

2

Visual Styles panel automatically switches to that visual type

3

Make changes and see them applied to the selected visual instantly

4

Perfect for quick, targeted adjustments

Pro Tip: Use this feature to quickly style similar visuals - click each one and apply the same variant.

Testing Scenarios

Data Density

Test with different amounts of data:

  • • Few data points (2-3 series)
  • • Medium complexity (5-8 series)
  • • High density (10+ series)

Visual Types

Ensure your theme works across:

  • • Charts (column, line, area, pie)
  • • Tables and matrices
  • • Cards and KPIs
  • • Maps and custom visuals

Interactive States

Test all interaction modes:

  • • Hover effects and tooltips
  • • Selection highlighting
  • • Cross-filtering between visuals
  • • Focus mode expansion

Preview Best Practices

Start Simple

Begin with basic reports to establish your foundation colors and typography before testing complex scenarios.

Test Extremes

Check both minimal (1-2 visuals) and dense (10+ visuals) layouts to ensure your theme scales well.

Use Real Data

The sample reports use realistic data patterns. Pay attention to how your theme handles actual business scenarios.

Check Readability

Zoom out to 75% to simulate viewing on smaller screens. Ensure text and data remain clear.
