Hi all, I'm trying to use the Retrieval Methods to calculated the average and standard deviation (the event weighted ones) with an specific time range
StartTime: 2018/10/10 15:06:00
EndTime: 2018/10/10 15:46:00
Those date could be change by the user. So, I create two attributes StartTime and EndTime to let the user change it if they want.
And use relative expression to define the time range.
I've been review the PI square and I only find examples with moving time windows, like '*'- 10m.
But no with any Full Time Range .
Is there a way to configure this in a Retrieval Method? Is it possible?
And if is not, can you guys suggest me another way to calculate this?
