i have a simple PE tag, which is just the hourly average of a tag.
I am using the following equation: TAGAVG('Testtag','*','*-1h')
The tag 'Testtag' is getting neagtive values and hence, the PE tags also has neagtive values.
How can i filter out the neagtive values and use only the positive values of tag 'Testtag'.
Thanks in advance,
