This video introduces the concept of ranking values in DAX using the RANKX function. You'll see a quick overview of the RANKX, RANK.EQ and RANK functions before using the RANKX function to create a calculated column. You'll learn how to control the sort order of the ranking, as well as how to deal with tied results using either a Skip or Dense rank. You'll also see how to use the RANKX function to rank aggregated values in a measure, including how to use the ALL function to ensure the ranking is evaluated correctly. You'll learn how to hide ranked values on total rows in a visual using the HASONEVALUE or ISINSCOPE functions, and how to use ALLSELECTED to rank only the values currently displayed in the visual. You'll also see how to return only the top 3 results based on the rank. The final part of the video explains how to calculate ranks for different levels of a group hierarchy in a matrix visual, including how to calculate subtotals correctly, and how to return a rank for each level of grouping.
