Summary
This chapter is a door opened to unlimited power. With the right dataset and calculations, you can build absolutely anything you want. Yes, it requires a bit, and sometimes, a lot of practice, but mastering Tableau goes through this. As the title of this book says, we're only getting started here!
In this chapter, you learned the basics of Calculated Fields. With simple examples, you learned why aggregation is so important, created your first calculations, and used your first Tableau functions. In the second part of this chapter, things started to get a bit more complicated, as we looked at two types of special functions: Table Calculation and LOD. Table functions are applied after the aggregations and can be computed in various ways. You can use them to calculate ranks, difference, percentages of totals, and more. LOD can ignore dimension filters and even remove duplication. Both are powerful; both require practice.
In the next chapter, you'll learn how to use all the analytics...
