You can customize a visual's title, font size, style, colors, data labels, and other formatting options. Select a visual on the report canvas and use the Format pane to modify its appearance.
The Format pane has two main sections:
Note: Recent versions of Power BI Desktop introduce On-object Interaction, which allows many formatting options to be accessed directly from the report canvas. However, the complete set of formatting options remains available in the Format pane.
In Power BI, the "General" section within the "Format" pane provides essential options for customizing and fine-tuning the selected visual's appearance. The General section contains formatting options that apply to the overall visual, including its size, position, title, effects, header icons, tooltips, accessibility settings, and other general properties.
The “General “section includes options such as
Properties – In the "Properties" section, you can adjust the size of the visual and its position on the page, along with adding padding to ensure it fits perfectly within your report layout.
Title –The "title" in the "General" section allows you to name the visual and change how the title looks. You can make the title bigger or smaller, choose its color, and decide where to put it on the report page. It helps you create a clear and attractive report with visuals that have clear names and styles.
Effects – The Effects section allows you to customize the appearance of a visual by applying options such as background color, borders, shadows, transparency, rounded corners, and glow effects. These formatting options help improve the visual appearance of your reports and draw attention to important insights.
Header icons –Header icons refer to small graphical symbols or images placed at the top of a visual. These icons serve various purposes and provide quick access to different functionalities and actions within the Power BI. For example, you can enter Focus mode, export data, show the visual as a table, drill through to related pages, spotlight a visual, copy the visual, and access additional options.
Header icons can also be customized by showing or hiding specific icons based on report requirements, improving the report viewing experience.
Tooltips –In Power BI, tooltips are like little boxes that pop up when you move your mouse over a data point or item in a report. They show extra information related to that data, helping you understand it better. Tooltips are a handy way to get more insights without overcrowding the main visual, making data exploration easier and more informative in your reports and dashboards.
Tooltips can be customized to show relevant details, such as the exact values, percentages, or descriptions related to the data point.
Power BI also supports Report Page Tooltips, which allow report authors to create fully customized tooltip pages containing charts, KPIs, tables, images, and other visuals. These interactive tooltips provide richer context without cluttering the report.
Alt text-In Power BI, alt text (alternative text) is a brief description that can be added to images and visuals. It provides a text-based representation of the visual content, making it accessible to people with visual impairments or those using screen readers. Adding meaningful Alt Text helps improve report accessibility and supports users who rely on screen readers.
Visual
The "Visual" section provides various settings to customize and fine-tune the appearance and behavior of the selected visual element in your report. This section provides various settings specific to the type of visual you have chosen.
Some common options you may find in the "Visual" section include:
X-Axis and Y-Axis- You can format the labels, titles, and gridlines of the X and Y axes to make the visual easier to understand.
- Title – Add or edit the title for X & Y axes and can adjust its font size, color and alignment.
- Axes Type – Choose between “Categorical” (Text-based fields) or “Continuous” (numerical data) for both axes.
Legend – You can show or hide the legend, which explains the colors or categories used in the visual. Customize the position of the legend, adjust the font size, color and can add title to the legend.
Gridlines – Customize the appearance of gridlines (Dotted, Solid, Dashed). You can also customize the gridline color, transparency, and width to improve readability while keeping the report visually clean.
Zoom slider - It allows you to adjust the level of zoom or magnification applied to a visual or data visualization. By using the zoom slider, you can focus on specific parts of the visual to see more detailed information or zoom out to get a broader view of the data.
Data Labels- You can choose to show or hide data labels on the visual to display the actual values directly on the elements. You can control the position of data labels to avoid overlap and enhance readability. Recent Power BI updates provide additional formatting options such as display units, decimal precision, background color, and series-level customization for supported visuals.
Plot area background - The plot area is the space where the actual data is displayed within a visual. Depending on the visual type, you can customize the plot area's background using colors, transparency, and other supported formatting options to better match your report's overall design.
Customizing the plot area background helps you align the visual with your report's theme and design, making it more engaging and effective in conveying insights from your data.
Conditional Formatting-Power BI provides Conditional Formatting to dynamically change the appearance of visuals based on data values. You can apply formatting such as background colors, font colors, icons, data bars, and color scales using rules or field values to highlight trends and important business insights.
Analytics-Many Power BI visuals support Analytics features such as Constant Lines, Average Lines, Trend Lines, Forecasts, Error Bars, and Percentile Lines. These features help users identify patterns, compare values, and gain deeper insights from their data.
These analytical features help users identify trends, compare performance, and make more informed business decisions.
Best Practices
• Use consistent colors and fonts throughout the report.
• Align visuals properly for a clean layout.
• Use data labels only when they improve readability.
• Add meaningful Alt Text to improve accessibility.
Conclusion
Formatting plays a vital role in creating clear, professional, and visually appealing Power BI reports. By using the General and Visual formatting options, you can customize every aspect of a visual to improve readability and effectively communicate insights. With recent enhancements such as On-object Interaction, Report Page Tooltips, improved Header Icons, and enhanced formatting capabilities, Power BI Desktop provides greater flexibility for designing interactive and user-friendly reports. Applying consistent formatting and following best practices will help you create reports that are both engaging and easy to understand.
