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,
