We at the Data School love Tableau. It is intuitive and accessible for new users but also has depth and enough tools for more advanced users to really create. On October 18th Tableau released version 2022.3 and it has many improvements and features designed to improve the user experience. From a data users point of view the 3 biggest changes are the Data Guide, Dynamic Zoom and Table Extensions capabilities. So what are they all about?

Data Guide

This is a handy little feature that provides some “how to” with your dashboards. If you have ever built or received a dashboard and wondered what it all meant? Then this is for you.


Located on the dashboard editor next to the Show Me is now a pair of binoculars. This takes you to the data guide. Within this pop out menu is the opportunity to include a description of your visualization and any relevant links. Further down we can see an overview of the data and some extra analysis of outliers etc. from the dashboard. It’s a nice overlay using its AI to help explain dashboards to users and ultimately make them more insightful and digestible.

Dynamic Zone Visibility

This new aspect simplifies the task of displaying parts of a dashboard to a user depending on their viz interactions. Dashboard space has always been at a premium, but now using dynamic zone viz builders can show or hide information based on how the user interacts with the viz. This can be accomplished using fields or parameters and can affect tiled or floating containers on the dashboard making them appear or disappear. A very nifty use case is demonstrated by Samuel Parsons. His use of Boolean parameters to zoom in on individual charts on a dashboard. Check it on Tableau Public.

Table Extensions

The final new feature I will discuss is that of table extensions, which is located on the data source tab. It allows for extensions from R, Python and a whole host of analytical tools to be piped into Tableau. This makes it possible to augment, re-shape and enrich data in even more meaningful ways
