AAOmega is a dual-beam, bench-mounted spectrograph of the 3.9 m Anglo-Australian Telescope. No shortage of tools exist for plotting astronomical spectra like those generated by AAOmega. Perl code is presented here however, for metaprogramming TikZ spectral plots styled to be visually harmonious with LaTeX documents. From a functional standpoint, the Perl software co-plots FITS data from both arms (red and blue), and autogenerates axis tick marks and labels customised to the data bounds. Automatic plot adaptation is not only to flux, but also to wavelength, automating visualization across AAOmega's configurable wavelength range. Example plots are presented, such as for 2dfdr-reduced spectra from the Two Degree Field multi-object fibre feed to AAOmega.
