The Tableau Workshop

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.

Preface

Types of LOD Calculations

In this section, you will learn about the various LOD calculations. There are four LOD calculation types:

  • FIXED
  • INCLUDE
  • EXCLUDE
  • Table-Scoped

You will now learn about each of these LOD calculations in greater depth. You will also learn their application in visualizations by performing an exercise for each.

FIXED

FIXED LOD calculations compute an expression using specified dimensions. An example would be identifying the top-performing product categories per region per country. This can easily be done using FIXED LOD calculations.

Exercise 9.02: Creating a FIXED LOD Calculation

In this exercise, you will calculate SUM(Profit) fixed at a Country level. Suppose, as a country-level manager, you are only interested in the profits generated at country level, but occasionally would like to hone in on the Region level of that country. Now, you will compute a measure at a specific dimension level, rather than making calculations...
