In this chapter, we covered some of Tableau's analytic tools, which allow us to create reference lines or bands, cluster data in similar buckets, identify trends, and forecast what our data will look like in the future. This allows us to highlight some of the useful information that might have been missing from the views (such as an average line or maybe a constant band to tell us when a project started and finished), and this helps bring meaningful insight to our data.

This chapter concludes our exploration of worksheets, for which we now have all the tools required for the exam. We will study how to link and present different worksheets in a single consolidated view using dashboards in the next and last chapter of this book.
