To tune and improve Tableau performance, Tableau has a built-in workbook performance grader that enables you to analyze your workbook’s performance. This is in the form of Tableau Performance Recording. For Excel files that aren’t too large, you probably won’t need these techniques. But as your files get larger (both data sources and your workbooks with calculations), and especially as you are…
Tableau story points are a powerful, often underutilized, feature of Tableau. Most people are used to seeing tables of numbers from Excel, with maybe a chart or two. It’s a manual process to create and maintain those, and they aren’t always done well. Further, an Excel chart can encode one or two values at the most. A Tableau chart can encode…

Why should you use a slope chart in Tableau? Imagine we have the following chart: How useful is this? How much insight can we pull…
A Tableau Pareto chart is a type of Tableau chart that contains both bars and a line graph, where individual values are represented in descending order by bars, and the cumulative total is represented by the line. It highlights the 80/20 rule, which states that typically 80% of the results are caused by 20% of the factors. For example, 80% of sales are…
Tableau sparklines are very small line charts, usually drawn without axes or coordinates. It presents the general variation in values trended over time, in a simple and highly condensed way. Tableau sparklines are small enough to be embedded in text. While the typical chart is designed to show as much data as possible, and is set off from the flow of text,…
