Analytics & Calculations

The Date and time format in PI System Explorer's Preview-Results pane are not displayed according to the end user's operating system date & time format defined. This is an inconsistent behavior to that of PI System explorer in general sine the...

I would like be able to use a variable as index instead of an integer number in \Elements[@index=variable] so I can always get attribute values of my child elements eventough the relation to my child element isn't always the same.

It would be nice if the configuration of an analysis was saved in memory when switching between types (expression, rollup, event frames or SQC). This way if a user accidently changes type, their work would not be lost.

During bulk recalculation or backfill, enhance the PI Asset Analytics engine to prioritize the calculation of analyses that act as inputs into higher level "daisy" chain analyses. This would address performance issues at large scale, as described ...

I find myself making analytics on child elements which by themselves have limited value, but are needed to get rollup analyses to work. This adds complexity to the design of AF. Two ideas would improve this: 1) Count # of attributes that meet a c...

Some Analytics fail due to a tag not existing. It is possible to test for a Bad value via the BadVal() function, however, this does not work if the tag does not exist. Consequently the equation will not run. This caused me many hours of debugging ...

I would like to create a custom AFAnalysisRule that allows us to leverage the resources on the PI Analysis Service to perform calculations that the Analysis Service currently cannot perform. These calculations include matrix operations, array oper...

Similar to the Exit() function, a Continue() function would be very helpful in reducing the calculation load on my analysis service, in this case by not fully executing variables if a condition is true. For example, if I'm evaluating the state of ...

Hello, We have a use case that would benefit from being able to insert into an AFTable from an analysis. This would work in the same way that event frames do, where a trigger condition is meet that causes the row to be inserted. The variables from...

Consider implementation performance analysis service statistics in AF Explorer which is now performed in a complicated way by exporting data to Excel, rearranging and viewing in a pivot table. It would also be useful to be able to retrieve that da...
