Chapter 5
Table Calculations and Level of Detail Calculations
Standard calculated fields as introduced in Chapter 4 are always evaluated at the level of the individual mark. With Table Calculations and Level of Detail (LOD) Calculations, you can break out of that mold.
Table Calculations allow you to create computations that span across different marks in your visualization. Predefined Quick Table Calculations make it possible to quickly include several commonly used calculations without having to type any formulas.
LOD Calculations are similar to normal formulas in a calculated field, except that they allow you to define which dimensions should be used to break up the data. In other words, you are not limited by the dimensions used in the construction of your chart.
By the end of this chapter, you will be able to:
- Understand the order in which different work processes happen in Tableau and how that affects the different types of calculations.
- Use Table Calculations for in‐depth...
