SUM WHERE, out there: A Visual Introduction to DAX Basic Aggregators and Filters
Our resident #powerbi and DAX wizard Brian Grant provides a Visual Introduction to DAX Basic Aggregators & Filters. It’s a great explanation of the simplest of simple in DAX, the SUM function, and showing how it actually arrives at the number you are expecting. Brian also explores what relationships actually do between tables and how filters themselves are really just tables. With actual examples, the theoretical will become concrete, and the simplicity of the language will start to reveal itself.
