After the multi-query join Grafana ranged the gauge cell across every numeric
field in the frame, so 31 blocks was drawn against a 675 MH/s maximum.
fieldMinMax on the blocks column restores the per-column scale. The gap and
drift quantiles are filtered with expr == expr so authors without samples in
the range show a blank cell instead of NaN.
