    Aggr and Set analysis

      Hi there qlikview community,


      I have used aggr and set analysis to product my expression which is:

      Aggr(Count({<SensorValue={"= SensorValue>= HighControlLimit"} + {"= SensorValue<= LowControlLimit"}>}SensorValue),ValidatorUnit,Sensor,SensorParam)


      The problem is that my expression does not behave as intented.As you can see in the attached pictures below it works perfectly when i select onle one sensor

      but it gives me some null values when i sellect all of them.

      Any idea why this is happening???
