I am facing an issue that I find a bit odd!
I am trying and calculate a total volume given a certain flow within a period of time with datalink.
There is a huge negative archived value (huge in amplitude, negative sign), which was causing my totalizer to return a negative number.
|Number of Values:||101|
So I thought it was an easy solution: just using a filter 'tag'>0.
Although I got a different number, it was still negative (closer to zero regarding the previous one, but still quite far).
For a wider period of time, when other negative numbers are retrieved, I've tested the 'tag=0' as a filter and didn't get zero as expected return.
Isn't this a strange behavior? Shouldn't this negative values be eliminated from the calculation prior to integration?
Shouldn't any totalizer filtered by 'tag=0' return zero???
