From the Rich Filters App configuration page, Jira administrators can enable/disable deprecated app features. If you are using any of these features, let us know; otherwise, these features will be completely removed in a future version of the application. You can use the check-boxes to re-enable them until they are completely removed.
- Σ Time Series: Allow Σ-values for time series
If this deprecated feature is enabled, an extra option preceded by Σ will be available for each numeric value in the time series configuration. Options preceded by Σ include for each issue the values of its sub-tasks. This feature will be removed in a future app version.
