The Format pane is your primary tool for visual customization. Access it by selecting any visual and clicking the paint roller icon. Here you can modify numerous properties including colors, fonts, borders, backgrounds, and data labels.
For chart visuals, you can configure axis settings such as titles, labels, ranges, and gridlines. The legend position, size, and formatting help users understand data categories. Data colors can be customized per series or using conditional formatting rules based on values.
Title configuration allows you to add descriptive headers with custom fonts, sizes, colors, and alignment. Background colors and transparency settings help visuals blend with your report theme or stand out when needed.
Data labels display actual values on visual elements. You can control their position, decimal places, display units (thousands, millions), and formatting. This makes charts more informative at a glance.
Conditional formatting is powerful for highlighting important data. Apply color scales, data bars, icons, or rules-based formatting to tables and matrices. This draws attention to outliers, trends, or threshold violations.
Interaction settings control how visuals respond when users click on other elements. Configure whether a visual filters, highlights, or remains unchanged based on selections elsewhere in the report.
Tooltips provide additional context when hovering over data points. Customize default tooltips or create report page tooltips for rich, detailed information displays.
Slicers require special formatting attention including orientation, selection controls, and visual style. Configure single-select or multi-select behavior based on user needs.
Finally, responsive layouts ensure visuals adapt appropriately across different screen sizes and devices, maintaining readability and usability in all viewing contexts.

Why Is This Important?
Formatting and configuring visuals is a critical skill for the PL-300 exam because it directly impacts how effectively data insights are communicated to stakeholders. Well-formatted visuals enhance readability, ensure accessibility, and help users quickly understand key metrics. Microsoft allocates significant weight to this topic as it represents real-world scenarios where analysts must create polished, professional reports.
What Is Formatting and Configuring Visuals?
Formatting and configuring visuals refers to the process of customizing the appearance, behavior, and interactivity of charts, tables, and other visual elements in Power BI reports. This includes:
• Visual formatting: Colors, fonts, backgrounds, borders, and titles • Data labels: Displaying values on charts and controlling their position • Conditional formatting: Applying rules-based formatting to highlight data patterns • Tooltips: Customizing hover information for additional context • Sorting and filtering: Controlling how data is ordered and displayed • Reference lines: Adding constant, average, or target lines to visuals • Analytics pane: Adding trend lines, forecasting, and statistical elements
How It Works
When you select a visual in Power BI Desktop, you access formatting through the Format pane (paint roller icon). The pane is divided into two sections:
Visual tab: Controls specific to the selected visual type such as legend placement, axis settings, data colors, and data labels.
General tab: Controls common across all visuals including title, effects (shadow, background), header icons, and tooltips.
For conditional formatting, right-click on a field in the Values well and select Conditional formatting to apply background colors, font colors, icons, or web URLs based on field values or rules.
Key Configuration Options:
• X-axis and Y-axis: Control titles, range, scale type (linear/logarithmic), and gridlines • Legend: Position, title, and styling options • Data colors: Assign specific colors to categories or use conditional formatting • Small multiples: Break visuals into a grid based on a category field • Error bars: Display uncertainty or variability in data points
Exam Tips: Answering Questions on Format and Configure Visuals
1. Know the Format Pane Structure: Understand the difference between the Visual tab and General tab. Questions often test whether you know where specific settings are located.
2. Understand Conditional Formatting Options: Be familiar with all five conditional formatting types - background color, font color, icons, data bars, and web URL. Know that these can be based on field values, rules, or gradient scales.
3. Reference Lines vs. Trend Lines: Reference lines show fixed values (constant, min, max, average, median, percentile), while trend lines show mathematical relationships in the data. Both are found in the Analytics pane.
4. Tooltip Customization: Remember that you can create report page tooltips by setting a page as a tooltip page in Page format settings, then assigning it to visuals.
5. Sorting Behavior: Visuals can be sorted by any field in the visual using the More options menu (three dots). Know that you can sort by fields not displayed in the visual.
6. Default Summarization: When configuring visuals, understand that numeric fields default to Sum while text fields default to Count. You can change this in the field settings.
7. Small Multiples Limitations: Be aware that not all visuals support small multiples. Line, bar, column, and area charts support this feature.
8. Accessibility Features: Know about alt text configuration and tab order for screen reader compatibility - these are frequently tested topics.
9. Practice Scenario Questions: Many exam questions present a business requirement and ask which formatting option achieves the goal. Focus on matching requirements to specific features.
