I've also found set actions to be valuable for cohort analysis. By creating sets based on specific criteria, such as customer segments or product categories, we can analyze the behavior and performance of different cohorts over time. It enables us to easily compare retention rates, revenue growth, or any other metric across these segments, helping us tailor our strategies and identify areas for improvement.

One thing to keep in mind when working with set actions is to consider the performance impact when dealing with large datasets. The more complex the set action, the longer it may take for the visualizations to update. It's important to optimize the queries and design efficient visualizations to ensure a smooth user experience.

Set actions have been incredibly useful in our projects. We used them to compare sales performance across different regions. By allowing users to select a specific region, we could dynamically update the visualizations to show the corresponding sales figures, trends, and comparisons with other regions. It made the analysis more engaging and provided actionable insights at the click of a button.

Set actions in Tableau allow users to dynamically group data points and trigger actions based on those selections. For example, you can create a set action to highlight specific data points when a user clicks on them, providing a more interactive experience. Additionally, set actions can be used to filter multiple sheets or dashboards based on a common set selection, improving the overall user experience in exploring related data.
