I walk through the Explain Data enhancements in Tableau 2020.2 using the Sample Superstore data set. I build a simple profit versus profit ratio scatter plot and show how you can now choose which fields feed the analysis and how the feature detects multiple extreme values.

## Key takeaways

- The 2020.2 side pane looks different because it uses the new data model, but you can still follow along with similar data
- You can now choose which dimensions and measures are included in the Explain Data analysis by browsing and adding or removing fields
- Explain Data makes sensible automatic guesses, excluding fields like latitude, longitude and the profit ratio already on the chart
- The feature can now spot and list multiple extreme values rather than just a single outlier
