Hi! Imagine a Force-time curve for a reciprocating piston. This curve will differ based on the loading on the piston, and over time a lot of other mechanical variations. I would like to make an envelope for the force-time curve of lets say N(Lets say 1000) timeseries, and then anything that's outside this range, should be marked as an outlier by Ignition. Envelope is defined here: [Signal envelope - MATLAB envelope](https://www.mathworks.com/help/signal/ref/envelope.html) ---

No equivalent out of the box. You might want to investigate the JScience jars as a possibility. ---

Oh, unfortunate. Seems like a very prolific application. Would have been nice to have this as an in-built capability. Maybe I'm coming in as somewhat of a newbie, but I have never integrated JScience or any Jars into Ignition. Do you think that there would be a pathway there? ---

Ignition isn't a high-speed data acquisition system. Is the data coming from elsewhere? ---

Data is coming from SQL. Also worth saying - low sampling frequency data can also have requirements like this one where an envelope qualifies the cycle. ---

To use arbitrary java jars, the simplest approach is to drop them into the appropriate folder under `lib/core` and restart your gateway. Then you can import classes from those jars into your jython scripts. If you need a simple install procedure, you would wrap the jars in a third-party module. Then expose selected classes or wrapper functions in a `system.something` scripting function namespace.
