Chapter 6. Level of Detail and Table Calculations
In the previous chapter, you learned how to use custom calculations to create new fields that add context and insights to the story that you are telling with Tableau Public. In this chapter, we will discuss how you can use table calculations and level of detail calculations to enhance the comparisons that you are making with the data. We will build on several of the calculations that we have created to show you how to make them more dynamic and contextual.
The table calculations are different from the traditional calculations because they are performed locally on the data in the cache, that is, the data that Tableau Public has used to create the visualization. Not all data that is in your data set is in use all the time. The data in the cache is what Tableau Public is using in the memory to render your visualization. Therefore, the data that you have filtered out will not be included in the table calculations.
