Description

Changing the chart zoom in the Single Metric Viewer changes the aggregation interval as well, such that sum and count result in other aggregated values, e.g.:

  • aggregation interval of 15m with peak values a bit above 7.000: single_metric_viewer_agg_interval_15m
  • same graph with expanded time window such that the aggregation interval is 30m now shows peak values a bit above 11.000 (sum over a longer time gives higher values): single_metric_viewer_agg_interval_30m

The tooltips in the chart show the value of the selected aggregation inteval. To provide some explanation to the user about the changing values in the graph it would be good to add the time interval to the tooltip, like sum over 30m.

Research direction
The issue is about adding the aggregation interval to tooltips in the Single Metric Viewer, which is part of Kibana's ML plugin. The relevant source code is likely in x pack/plugins/ml/public/application/timeseriesexplorer/components/timeseries chart or similar. Look for the tooltip component (e.g., using Vega or a custom tooltip) and modify it to include the aggregation interval label such as 'sum over 30m'. The chart's aggregation interval is derived from the time range; examine how the interval is computed and passed to the chart. The existing comments in the issue show expected behavior.
