1) You can show the FFT data in multiple charts or all together in one
2) Axis scaling (linear, logarithmic, Auto, manual)
3) X-Axis in Harmonic orders or in Hertz (Hz)
4) Showing Min / Max Values
5) Horizontal lines
6) Time-Frame for additional FFT calculation
The picture above shows visualization of Harmonics (50 orders), Higher Frequencies (200Hz
bands) and Supraharmonics (2kHz) of an EV charging station in one screen.
The following picture shows Harmonics, Higher Frequencies and Supraharmonics in
individual tabs.
