pub fn stat_keys() -> Vec<String>Expand description
The metric keys aggregated into the per-graph stats block via the mean
(compute_stats). Derived from [report.stats]: the keys whose
formula is a plain mean of their own metric over not_empty
(agg('<k>', 'avg', 'not_empty')). The richer aggregate formulas (percentiles,
all population, …) are parsed but not yet wired into the built-in stats.
