Question

What techniques can I use to enhance Power BI visuals for accessibility, including colorblind-friendly palettes and readable fonts?

To optimize the user experience, I need to monitor Power BI report usage and performance metrics effectively. I’m seeking methods to track user interactions, report load times, and other key performance indicators. Any insights on Power BI tools or settings for tracking and analyzing these metrics to make data-driven improvements would be useful.

• Accessibility in Power BI visuals can also be improved by making use of various strategies that will make your reports more usable to all users. First and foremost, adopt color palettes that are friendly to the color blind as they are very important to color-deficient users. This application can assist you in determining colors that are best to use for a certain type of color blindness, like red and green, which is also referred to as Coblis. In Power BI, any visual can be adjusted by using the colors defined in the section that is found under “Data Colors” when setting the colors of charts, graphs, and icons to be different. In addition, avoid using highly decorative or compressed fonts or set the font size to about 12 and above using clear fonts. Use high-contrast designs and allow such factors as text labels, legends, and tooltips to be readable. Last but not least, implement a description of your complex visuals in the form of text or tooltips for screen readers because they work effectively with Power BI, which has alternative text and titles for images or objects.

• In order to manage and analyze the usage and performance of Power BI reports, Power BI provides a number of built-in features and tools Power BI delivers. The most useful of these is the Power BI Service Usage Metrics report, which allows tracking the number of people using reports, user interactions, and frequency of usage. You can turn and configure this report in Power BI Service to see the statistics about the report usage, the specific pages that users navigate to inside the report, and the amount of time spent interacting with each report. In addition, if you want to drill deeper into the performance metrics of a report, use Performance Analyzer in Power BI Desktop. This tool displays how long it takes for each report to load, how long it takes to render each of the visuals, and how long it takes to execute each of the DAX queries. By looking into these metrics, you will be able to narrow down the issues regarding high loading time or visuals that are particularly heavy and may require optimization. In addition, you may want to consider using additional monitoring solutions such as Power BI’s REST API or Azure Application Insights that allow for in-depth logging and tracking of user metrics. This data should be scrutinized on a constant basis so that there will be more proactive and effective strategies in place to improve reports functionality and increase ease of use.
