Overview of this book

Learning Tableau has never been easier, thanks to this practical introduction to storytelling with data. The Tableau Workshop breaks down the analytical process into five steps: data preparation, data exploration, data analysis, interactivity, and distribution of dashboards. Each stage is addressed with a clear walkthrough of the key tools and techniques you'll need, as well as engaging real-world examples, meaningful data, and practical exercises to give you valuable hands-on experience. As you work through the book, you'll learn Tableau step by step, studying how to clean, shape, and combine data, as well as how to choose the most suitable charts for any given scenario. You'll load data from various sources and formats, perform data engineering to create new data that delivers deeper insights, and create interactive dashboards that engage end-users. All concepts are introduced with clear, simple explanations and demonstrated through realistic example scenarios. You'll simulate real-world data science projects with use cases such as traffic violations, urban populations, coffee store sales, and air travel delays. By the end of this Tableau book, you'll have the skills and knowledge to confidently present analytical results and make data-driven decisions.

Introduction

In any visualization, a virtual table is created based on the dimensions used in the view. This is added to the Columns, Rows, and Marks shelves.

Figure 8.1: Virtual table in the view

The highlighted area in the preceding figure consisting of the Rows, Columns, and Marks shelves will make up your level of detail. The empty canvas outline for dropping fields contains the virtual table that will be affected by table calculations.

A table calculation is simply a calculation that computes results based on the table segment in scope. You will learn about segments and scope in detail in the following sections. For now, assume it is the entire empty canvas area. All table calculations will only be computed within the empty canvas outline or the virtual table.

In previous chapters, you learned about visualization methods that present data in a meaningful way. There may be times where you need to analyze a table, such as when you want to find the...
