Creating measures using DAX
DAX (Data Analysis Expressions) Measures in Power BI are standard aggregation functions or dynamic custom expressions defined with the DAX formula language. Using this formula language, you can calculate, combine, and filter data that can return one or more values. DAX Measures are dynamic and user-defined formulas where results change depending on context. This article discusses the DAX Measures in Power BI, how to create and edit, and how to use them in Power BI Visualization reports.
