## What is the purpose of the change The Metrics Explorer chart only read `series.values`, so a PromQL query that returned native histograms (no scalar samples) was plotted as the empty state even though data existed. ## Brief changelog - `toNumericSamples` now falls back to the series' histogram samples when no scalar values are present - each histogram contributes a trend point: the observed `sum` in the metric's unit, falling back to the observation `count` when the sum is blank or non-finite (a blank field parses to `0`, so it is treated as missing) - scalar samples still take precedence when both are present - series drawn from histograms are marked with a "Histogram" tag in the legend, and the empty-state copy now reads "No samples" / "暂无数据" ## How was this patch verified - web: `MetricsExplorer.test.tsx` 15/15 (histogram-only renders from sums, blank sum falls back to count, scalar-over-histogram precedence, empty state); full `vitest run` 642/642; `tsc -b` and `eslint` clean Fixes #2492 -- This is an automated message from the Apache Git Service.
