Standard Spectrum plots for photometric analyses?

I'm a biochemistry student and currently, I had to plot some spectrums of different pigment-mixtures we analyse with a photometer. I would like to plot some "standards-spectrums" of some special pigments over my measured graphs to show similarities and differences. I know that for geological plots there are some data files for maps of different countries on which they can plot for example earthquake data. Does something like this also exist for spectrums (e.g. carotenoids, chlorophylls etc.)? It would be very great.

It seems to me that you need only the plot and hold functions.

In my experience, spectra are usually line plots. If you want to plot your spectra in three dimensions, see if the ribbon function will do what you want.

There are lots of libraries for standard chemicals with thousands of spectra ("signatures"). I don't know if they are in the public domain, and there are public repositories for them, or if they are just bundled into spectroscopy software like Opus. I'll try to remember to ask our spectroscopist, who sits right next to me, tomorrow and let you know.

Yes such a library is what I'm looking for, thanks. Would be great if there is an open one. Otherwise - may you can get access over universities?

There are a lot of open (source) databases.... just search on Google for:

osdb.info/

http://osdb.info/ .... https://github.com/stuchalk/OSDB/

and Things like that.... via pubchem, you'll find em.
