DAX Cookbook

By: Greg Deckler

Overview of this book

DAX provides an extra edge by extracting key information from the data that is already present in your model. Filled with examples of practical, real-world calculations geared toward business metrics and key performance indicators, this cookbook features solutions that you can apply for your own business analysis needs. You'll learn to write various DAX expressions and functions to understand how DAX queries work. The book also covers sections on dates, time, and duration to help you deal with working days, time zones, and shifts. You'll then discover how to manipulate text and numbers to create dynamic titles and ranks, and deal with measure totals. Later, you'll explore common business metrics for finance, customers, employees, and projects. The book will also show you how to implement common industry metrics such as days of supply, mean time between failure, order cycle time and overall equipment effectiveness. In the concluding chapters, you'll learn to apply statistical formulas for covariance, kurtosis, and skewness. Finally, you'll explore advanced DAX patterns for interpolation, inverse aggregators, inverse slicers, and even forecasting with a deseasonalized correlation coefficient. By the end of this book, you'll have the skills you need to use DAX's functionality and flexibility in business intelligence and data analytics.

Applying Advanced DAX Patterns

This chapter contains some of the more mind-bogglingly hard problems to solve in DAX that I have encountered over the years, as well as a few DAX oddities such as creating Scalable Vector Graphics (SVG) graphics and animations. This is not to say that the previous chapters do not have some very hard DAX recipes. This chapter, however, has an abundance of truly complex DAX code that solves some of the more vexing problems you might encounter. Either through brute force or DAX code wizardry, this chapter should put to rest any notion that DAX cannot solve just about any calculation you might throw at it!

The following is the list of recipes that we will cover in this chapter:

  • Using dynamic ABC classification
  • Creating an inverse slicer
  • Unpivoting columns in DAX
  • Transposing tables
  • Repeating counter with criteria
  • Using across then down
  • Using matrix multiplication...
