When designing reports in Power BI, it is essential to consider the diverse range of users who will interact with them. By implementing best practices for accessibility, such as clear structure, color contrast, proper labeling, and alternative text for visuals, you can create reports that are easily navigated and understood by keyboard or screen reader users.
Color Contrast
- Choose colors with sufficient color contrast.
- To set the color of titles, navigate to Visualizations > Matrix > Format > Title. The font color for the title can be changed here, as well as the text size and font family.
- To set the color of graph lines, navigate to Visualizations > Line chart > Format > Data Colors. These can all be customized in Power BI Desktop.
- Use WebAIM’s color contrast checker.
Markers for Data Visualizations
- Select Show Markers. Different marker shapes should also be used for each line.
Tab/Focus Order
- The default tab or focus order may not be logical for users using the Tab key and keyboard navigation to move around the report region.
- To set the tab order, you can open the selection pane (under View) and select Tab Order.
- You can drag and drop the fields to edit the tab order. Set the Title first on each slicer in order to know which slicer you are ordering – turn off the Slicer Header and use the Title instead.
Data Visualization Labeling
The Title of the data table or line chart can be dynamically updated as slicers are selected.
