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.

Summary

Level of detail expressions greatly extend what you can accomplish with calculations. You now have a toolset for working with data at different levels of detail. With fixed level of detail calculations, you can identify the first or last event in a series or whether a condition is ever true across entire subsets of data. With include expressions, you can work at lower levels of detail and then summarize those results in a view. With exclude expressions, you can work at higher levels of detail, greatly expanding analysis possibilities.

In the next chapter, we'll explore the final main type of calculations: table calculations. These are some of the most powerful calculations in terms of their ability to solve problems, and they open up incredible possibilities for in-depth analysis. In practice, they range from very easy to exceptionally complex.
