[AstroPy] Current best replacement for splot

[Peter Weilbacher]

Hi Nic,

this is tough. splot for many people is still the #1 reason to install
IRAF.

I think SpecViz (http://specviz.readthedocs.io/en/v0.4.4/index.html) is
meant as a Python replacement. Judging from the docs, its interface
seems to be a lot more complicated (nothing easier than pressing k-k to
measure a line with splot), although probably more powerful in the long
run.
When I tried it a few weeks ago, I didn't even manage to load one of my
FITS spectra. Maybe you have more luck...

   Peter.
