Successes and failures are separate series rather than a signed sum, so a bucket containing both stays readable. Bucket width follows the zoom level with a 12h floor. Rendered as a timeseries rather than a barchart panel: barchart joins all series into one frame and returns no data at all when some of them are empty, which is the normal state here (no failures, no skips). Caveat: the first run after a job/repo first appears registers no change and is not counted.",
