i can get 4 point data from bigquery, but i want to show a continuously line, $__timeGroup doesn’t work to fill missing point as zero.
my query is
SELECT
$__timeGroup(started_at, 1d, 0),
CAST (service_name as String ) AS metric,
`count` as count
FROM
`t_table`
WHERE
$__timeFilter(started_at)
and service_name="xxx"
order by started_at asc
