## Visualization

Figure: Time series of the intensity as a function of velocity of 9000 dumped spectra part of 200 OTF scans. Only 7 commands are needed to obtain this result, 4 of which are mandatory and 2 of which just there to improve the visual aspect.

The following list of commands is all you need to plot as a single image (see Fig. ) 9000 dumped spectra part of 200 OTF scans observed in 4 hours.
