NARVAL is the spectropolarimeter at the TBL 2m telescope of pic du midi. Spectra are available after a year on the archive: http://tblegacy.bagn.obs-mip.fr/narval.html
Look at the "quicklook" tab for "NOVACyg1600" (P Cygni) - there are several spectra available to us. I believe the one interesting for us are the "I" profiles (Intensity), the Q/U/V beeing the polarimeter measurements.
You can import thos spectra with "fv" (Fits viewer) and export the table wavelength / flux so it can be printed with Gnuplot for exemple. Be careful as those are special FITS files with wavelength overlap due to the echelle orders overlap. But it is still easy to plot:

Note: there are plenty other stars spectra in this archive to look at!
