[AstroPy] Current best replacement for splot

[Adam Ginsburg]

Hi Nic,
     pyspeckit (pyspeckit.readthedocs.io) is a reasonable replacement.  Its
UI was inspired by splot, though it has a different set of keybindings.
This page:
http://pyspeckit.readthedocs.io/en/latest/interactive.html
shows an interactive example that's similar to splot.

     Longer term, the astropy project includes development on several
spectroscopy-related tools including visualization, but these tools are
still in an early stage of development.
