CTAN update: pgf-spectra
LSE data renormalized to lower values within TeX capabilities. This prevents 'Dimension too large' errors and subsequent errors in spectrum drawing when using the 'relative intensity' key. Added maximum intensities in IR, visible an UV ranges for both data sources (NIST and LSE). Now, when using the 'relative intensity' key, the interval of wavelengths is detected and the respective maximum intensity is used. For example, if the spectrum is within the visible range, say between 400 and 700 nanometers, the maximum visible intensity will be used. The same is true for ranges only in IR or UV ranges. But, if the spectrum to be drawn is in more than one region - for example, from 300 to 1000 or from 400 to 1000 or from 300 to 700 nanometers - the maximum intensity that will be used is defined as the maximum intensity of all data. Fixed some typos in the manual.

pgf-spectra – Draw continuous or discrete spectra using PGF/TikZ
The purpose of this package is to draw the spectra of elements in a simple way.
There are data available for the spectra of 98 elements and their ions (from the NASA database and from NIST). It also allows the user to draw spectra using their own data.
