Summary
PR #270922 adds a UnifiedHistogramChart above the Alerting v2 episodes list, showing count of active episodes over time within the selected time range. Users can break down the chart by Status, Rule, Acknowledged, or Assignee; selections and time interval persist in the URL. Brushing the chart updates the global time filter. Series are color-coded to match status badges (red=active, green=inactive, blue=recovering, yellow=pending), and a cap warning appears when the 10,000-episode query limit is hit. Alerting v2 remains under the xpack.alerting_v2.enabled feature flag with no public documentation.
Why this needs docs: The histogram chart is a prominent interactive visualization that substantially changes how users interpret alert episode trends on a page that has no public docs; it must be documented when Alerting v2 reaches public availability.

Alerting v2 alert episodes list (new page needed) > Episode histogram chart
- What the docs say: No public Alerting v2 documentation exists yet.
- What to add: When creating Alerting v2 docs for the episodes list page, document the histogram chart above the episodes table. Cover: breakdown options (Status, Rule, Acknowledged, Assignee); time interval and breakdown persistence in the URL; brushing to update the global time filter; color coding matching status badge colors (red=active, green=inactive, blue=recovering, yellow=pending); and the 10,000-episode query cap warning. Stack only (technical preview, feature flag required), from 9.5.0.
