In this chapter, you’ll learn how to create custom calculations using Microsoft’s formula language, DAX (Data Analysis Expressions). You’ll learn how to expand your source tables with calculated columns, before progressing to writing calculated measures to help summarize your data.

Getting Started with DAX

In this chapter, you'll learn about context in Power BI and how it plays an important part when building reports. Next, we'll learn how to use iterator functions to evaluate data at a row level. We'll then introduce you to the CALCULATE function to help you filter your data and finally, we'll show you how to use variables to make writing DAX functions more efficient.
