Can I manually insert a bad value from a pi analysis?

I'm running some anlysis that are dependent on a few other tag's data being present and non-zero. For the periods where the data is there the calculation is fine, however during the "gap" periods PI extrapolates linearly between two points at either side and it really throws off further data analysis & visualization (huge straight diagonal lines on charts etc).


With gaps in sensors I just insert a bad value such as "ComFailure" or something, and PI doesn't sub-sample or display between the values.


How do I insert one of these as part of an analysis?
