How To Smooth A Graph In Origin | Baseline Correction | Raman Spectra Baseline Correction Apr 2026

To optimize your Raman spectra in Origin, follow these steps for professional smoothing and baseline correction.

Smoothing helps remove high-frequency noise from jagged experimental lines without losing the core signal. To optimize your Raman spectra in Origin, follow

: Highlight your data or click on the graph, then go to Analysis > Signal Processing > Smooth > Open Dialog . Method Selection : Method Selection : This removes background signals, such

This removes background signals, such as fluorescence or Rayleigh scattering, which are common in Raman spectroscopy. Origin Help - Smoothing - OriginLab Step 2: Baseline Correction : Recommended for Raman

: Use the Auto Preview feature. Adjust the Points of Window —a higher value creates a smoother line, but too high can broaden your Raman peaks. Step 2: Baseline Correction

: Recommended for Raman spectra as it preserves peak heights and maximum information better than simple averaging. Adjacent-Averaging : Good for simple noise reduction.
