PI TagMedian function need to be added in AF analysis.
Please add PI TagMedian function in AF analysis like PI TagAvg and PI TagMean. Currently Median function is available but it cannot be applied for archive values of PI Tags during particular time range
Planned for 2018 R2. The Median function will support analytics array introduced with the 2018 release.

The Median function now supports arrays, but that's not what the suggestion is asking for.
I think that it would be interesting to see the timeweighted implementation of TagMedian.
