my table is like this:
and my idea is to make a graph that shows, over “fecha_revision” as the timeline, two lines, one with the number of "NOK"s over the time and other line with the "OK"s over the time (“status” column).
i tried with this
SET DATEFORMAT dmy
SELECT
convert(date,fecha_revision) as time
,status as metric
FROM
db72a.dbo.revisiones
and im not getin any graph. please help
