Learning Tableau 2020 - Fourth Edition

Overview of this book

Learning Tableau strengthens your command on Tableau fundamentals and builds on advanced topics. The book starts by taking you through foundational principles of Tableau. We then demonstrate various types of connections and how to work with metadata. We teach you to use a wide variety of visualizations to analyze and communicate the data, and introduce you to calculations and parameters. We then take an in-depth look at level of detail (LOD) expressions and use them to solve complex data challenges. Up next, we show table calculations, how to extend and alter default visualizations, build an interactive dashboard, and master the art of telling stories with data. This Tableau book will introduce you to visual statistical analytics capabilities, create different types of visualizations and dynamic dashboards for rich user experiences. We then move on to maps and geospatial visualization, and the new Data Model capabilities introduced in Tableau 2020.2. You will further use Tableau Prep’s ability to clean and structure data and share the stories contained in your data. By the end of this book, you will be proficient in implementing the powerful features of Tableau 2020 for decision-making.

Relative versus fixed

We'll look at the details shortly, but first it is important to understand that table calculations may be computed in one of the two following ways:

  • Relative: The table calculation will be computed relative to the layout of the table. They might move across or down the table. Rearranging dimensions in a way that changes the table will change the table calculation results. As we'll see, the key for relative table calculations is scope and direction. When you set a table calculation to use a relative computation, it will continue to use the same relative scope and direction, even if you rearrange the view. (The term here is different from Relative To that appears in the UI for some quick table calculations.)
  • Fixed: The table calculation will be computed using one or more dimensions. Rearranging those dimensions in the view will not change the computation of the table calculation. Here, the scope and direction remain fixed to one or more...
