FFT Trend
Please provide a FFT (Fast Fourier Transform) frequency analysis trend. Best case scenario would be to right click (or otherwise select) a trend trace and convert back and forth between FFT and linear trends. It is indispensable for troubleshooting and determining frequency relationships and anomalies.

we are using FFT currently in analyzing PID controller strain. FFT has broad application. We have built a custom symbol in PI vision for FFT analysis. Works well as an ad hoc data science tool and links nicely to event frames in pi vision.

This would be a valuable feature - provides a way to identify process industry oscillations and variability due to the following:
- process upsets
- equipment problems
- control system oscillations due to tuning and valve issues -

THis would be useful in so many ways

This is needed in a range of cases. One broad example is machine vibration data from accelerometers for condition based maintenance.
