One exception to this is when the data is rendered in a matrix rather than a table: the total in the accessible Show Data table is positioned at the top rather than the bottom where we see it visually. The data in the accessible Show Data table will render in the order it is shown in the visual, so you can control that in your design. Show Data table at top level Show Data table after expanding down a level When they do this, the accessible Show Data table changes to what is currently shown in the visual. Keyboard (and screen reader) users can also access the menu options to drill down a level and expand down a level. Based upon my testing so far, it also works on custom visuals (for the most part). Props to the Power BI team for making that work. Why does this matter? When we talk about charts on a report we tend to say something like “That sales by region bar chart is….” Now someone using a screen reader can also follow that reference. It’s also pretty cool that when the screen reader encounters a visual on the report page it announces the visual title, the chart type, and the alt text. These features are consistent across Power BI Desktop and. They have added keyboard shortcuts to navigate between pages, examine the visuals on a page, and show the data in an accessible format. Power BI is off to a good start with screen reader accessibility and keyboard navigation, but there are some gaps. So here’s my second blog post (the first on my Data Savvy blog) with more of what I learned from this experience.
It was a very interesting and enlightening experience that provided enough content for multiple blog posts. He helped me test various features and do the screen capture you see in the video embedded in the BlueGranite blog post.
This all came about because I got the chance to work with my friend Dave Bahr, an accessibility specialist who is also blind and an advanced user of screen readers. And it shares several tips to make your report more accessible to screen readers and those who navigate via keyboard only. It contains some good reasons why accessibility should be considered when it comes to usability features of any web property or data viz. I recently wrote a post on the BlueGranite blog called Improving Screen Reader Accessibility in Power BI Reports.
