Charting regressions per month
I think it could be beneficial to understand the number of issues labelled with the regression label that are raised each month.
Looking at the historical regressions, it seems fairly common for team labels to also be applied. I don't see much value in mapping this to team (even though it's already possible), rather just to count the number of known regressions in total that are raised per month.
Chart proposal
X: Month Y: Regression count (open and closed issues)
Work needed
Queries for issues per label per month are already in use so this should just be a case of adding a new route, view and chart
I think a new page regarding regressions per project would be best
Notes
We could chart this daily too, to be able to see when regressions are most commonly raised. I imagine during the RC phase and in the period following the release. Because regressions are usually noticed on staging during the QA phase or by users whose established workflows have been affected by a change introduced in a new release.
