Mental model
A Spectral Graph is a spectrometer readout. It plots intensity across a wavelength range — for spectral sensors (color, NIR, light analysis).When to use it
- Spectral sensor output
- Wavelength-vs-intensity plots
Settings
General / Style
- Chart type · start / end (nm) — spectrum range
- Min / Max value · auto scale — Y-axis
- Data smoothing · max data points in history
- Show grid · current value badge
Example — push a spectrum from firmware
