Learning Tableau 2022 - Fifth Edition

By: Joshua N. Milligan

Overview of this book

Learning Tableau 2022 helps you get started with Tableau and data visualization, but it does more than just cover the basic principles. It helps you understand how to analyze and communicate data visually, and articulate data stories using advanced features. This new edition is updated with Tableau’s latest features, such as dashboard extensions, Explain Data, and integration with CRM Analytics (Einstein Analytics), which will help you harness the full potential of artificial intelligence (AI) and predictive modeling in Tableau. After an exploration of the core principles, this book will teach you how to use table and level of detail calculations to extend and alter default visualizations, build interactive dashboards, and master the art of telling stories with data. You’ll learn about visual statistical analytics and create different types of static and animated visualizations and dashboards for rich user experiences. We then move on to interlinking different data sources with Tableau’s Data Model capabilities, along with maps and geospatial visualization. You will further use Tableau Prep Builder’s ability to efficiently clean and structure data. By the end of this book, you will be proficient in implementing the powerful features of Tableau 2022 to improve the business intelligence insights you can extract from your data.

Fundamental table calculation concepts

Although it is quite easy to create quick table calculations, it is essential to understand some fundamental concepts. We’ll take a look at these next, starting with the difference between relative and fixed table calculations.

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 following two 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 relative here is different from...
