Hi all
I have some values grouped in three different categories.
I tried for days but I give up!! 
How can achieve something like this:
The three bars are similar to
SELECT
$__timeGroup(sample, ‘1w’) AS “time”,
sum( (power_ac - least(0, feedinpower) )605/1000 )/24 AS auto_consumo,
2nd SUM,
3rd SUM
FROM solax
WHERE
$__timeFilter(sample)
GROUP BY “time”
ORDER BY “time”
Any help?
