I've released some Python code for generating plots of time series which may be of use. The script takes a series of fits files and plots a graph of wavelength or velocity in the x axis, time in the y axis. The spectra do not need to be of completely uniform time intervals. These types of charts are often seen in papers when displaying dynamic line evolution.
An example graphic is attached. The scripts along with some other example plots are available at https://github.com/malclocke/dynaspec
