Ranking
In ranking, you can choose top and bottom N to control the number of categories. This option is helpful in filtering out the less important data and focusing on specific values. It's different from using filters in Power BI, which compare the overall data, whereas ranking is applied within a hierarchy.
Examples with top and bottom ranking configuration.
