Loading RAMAN experimental file

Here we load experimental LABSPEC spectra and plot them.

import spectrochempy as scp

Read and plot a single file

A = scp.read_labspec("ramandata/labspec/Activation.txt")

_ = A.plot()

Explore with different plot types

As a 2D dataset, we can display it as an image:

_ = A.plot_image()

or a contour plot:

_ = A.plot_map()

Read and merge multiple files

B = scp.read_labspec("ramandata/labspec/subdir")
_ = B.plot()

Uncomment the following line to display all figures when running the script directly with Python.

# scp.show()
