<pre>
Histogram buckets of the data series. Sorted by the min value of the
bucket, ascendingly, and the number of the buckets is dynamically
generated. The buckets are non-overlapping and completely cover whole
FLOAT64 range with min of first bucket being `"-Infinity"`, and max of
the last one being `"Infinity"`.
