NIR Spectral Data Analysis - Visualisation, PCA analysis and Clustering

This workflow takes preprocessed spectral data of multiple samples as an input and:
1. creates line plot visualizations colored according to available metadata, with the possibility to define an offset value between the lines for an easy comparison.
2. performs a PCA analysis and hierarchical clustering of samples
