Power BI Desktop has features that enable people with disabilities to more easily consume and interact with Power BI Desktop reports. These features include the ability to consume a report using the keyboard or a screen reader, tabbing to focus on various objects on a page, and thoughtful use of markers in visualizations.
Note: These accessibility features are available with the June 2017 Power BI Desktop and later releases. Additional accessibility functionality is planned for future releases as well.
With the accessibility enhancements, you can consume a Power BI Desktop report with a keyboard or a screen reader with the following techniques:
You can switch focus between the report page tabs, or objects on a given report page, using Ctrl+F6.
When focus is on report page tabs, use the Tab or Arrow keys to move focus from one report page to the next. The title of the report page, and whether it is currently selected, is read out by the screen reader. To load the report page currently under focus, use the Enter or Space key.
When focus is on a loaded report page, use the Tab key to shift focus to each object on the page, which includes all textboxes, images, shapes, and charts. The screen reader reads the type of object, and a description of that object that's provided by its author.
The following tips can help you create Power BI Desktop reports that are more accessible.
For Line, Area, and Combo visuals, turn markers on, and use a different Marker shape for each line.
- Using a different Marker shape for each line makes it easier for report consumers to differentiate lines (or areas) from each other.
As a follow on to the previous bullet, don't rely on color to convey information. Using shapes on lines (markers, as described in the previous bullets) is helpful.
Select a theme that is high contrast and color blind friendly from the theme gallery, and import it using the Theming preview feature.
For every object on a report, provide Alt Text. Doing so ensures that consumers of your report understand what you are trying to communicate with a visual, even if they cannot see the visual, image, shape, or textbox. You can provide Alt Text for any object on a Power BI Desktop report by selecting the object (such as a visual, shape, etc.) and in the Visualizations pane, select the Format section, expand General, then scroll to the bottom and fill in the Alt Text textbox.
Make sure your reports have sufficient contrast between text and any background colors.
Use text sizes and fonts that are easily readable. Small text size, or fonts that might be difficult to read, are unhelpful for accessibility.
Include a title, axis labels, and data labels in all visuals.
