Microsoft has announced its plans to improve the visualization experience across devices with the help of new responsive visualizations. As the name suggests, responsive visualizations can automatically adpat to display the maximum amount of data and insight regardless of the display size. As the display size reduces, responsive visualizations prioritizes the data view, for example removing padding and legend tweaks such as moving the legend to the top of the visualization and more. Check out the gif above to see this experience in action.
Power BI users can make their visualization responsive by going to the formatting pane of Power BI Desktop, under General, set Responsive to On. When responsive visualizations become generally available, Microsoft will make it default for all visualizations added to new reports.
