Daily maximum value and timestamp

Hello,

I need to get the daily maximum value and timestamp for a tag, and I also want to be able to trend the maximum values. I'm planning to do this trough AF.

 

I tried the below, and it looks great. It returns the maximum value and its timestamp but it only returns the maximum value for the current day. I get this "GetValues not supported for the relative time specifier " when trying to trend or get time series data.

 

 

Result:

Timestamp corresponds to the maximum value timestamp

 

Then, I tried using an analyses  "TagMax('Power','t','t+1d')". This way I am able to trend and get the maximum values for a period of time, but the timestamps are the time when the analysis triggered and not the time of the event.

Result:

Timestamp is the time the analysis triggered and not the maximum value timestamp.

 

 

Any idea how I could get the results I want?

Thanks,

Oscar
