I need to discard extreme values on a meta data point but the user interface found under 'Logging properties' that I have seen in video tutorials is not present. Using the SQL editor, I can see the fields that need changing but I would rather steer clear of delving into the database directly as I am a noob to Mango and don't want to do anything stupid. Please can someone advice me what I need to do to be able to configure extreme value discarding. If the answer is RTFM, please can someone point me to the right place as I simply haven't found it.
More details: I have a series of meta data points which measure time periods. For the sake of an example, let us say I have called such a point TIME. Each of these has two corresponding boolean* data points. One represents the point to begin the stop watch and the other represents the point to stop the stop watch. I'll call them START and END. I require only one data point from TIME for each START-to-on and END-to-on pair. This means I get unnecessary TIME values when START turns on, START turns off and END turns off. In all of these cases TIME returns undefined (I also tried null and NaN) which gets stored as a zero.
*I'm actually using multistate types and returning 1 or 0 as this was a work around to an unrelated problem.
Any help greatly appreciated.
