Hi All,
I am quite new to this so bring it to me gently 
I am using Grafana v8.0.5 on a pi and I have created a sql database on MariaDB that runs on a other PC. That all work its beeing filled at this moment.
SELECT
DateTime AS “time”,
CnlNum,
Val
FROM (table)
WHERE
$__timeFilter(DateTime) and
CnlNum = 201
ORDER BY DateTime
I can filter out in this case the 201
But it gives only dots and the values are not corresponding with the X-as
Hope I explained myself a bit
Thanks beforehand!
