Delta between rows

[CostinelRO]

Hello,

Starting from the bellow table(Delta is the desired output) I would like to get the delta between rows and from that data to make a graph.

Initially, every minute I had a value, but I used AGGR to get the hourly average( AGGR(AVG(values),ora).

What is the best way get the delta between the rows in order to display it in a graph ?

Thank you,

Costi

@CostinelRO  you an try below in expression. Make sure that your dimension is sorted by hour otherwise above function won't work as expected

=value-above(Value)
