Hi,

What is the correct syntax query to use non negative deriative function with sum of multiple field grouping by day ?

I try something like the exemple below but the result is not the result expected.

SELECT non_negative_derivative(sum(“A”), 1s) + non_negative_derivative(sum(“AAAA”), 1s) + non_negative_derivative(sum(“SRV”), 1s) FROM “bind” WHERE (“type” = ‘prod’) AND $timeFilter GROUP BY time(24h) fill(null)

Regards
