Description:

APLpy (the Astronomical Plotting Library in Python) is a Python module aimed at
producing publication-quality plots of astronomical imaging data in FITS format.
The module uses Matplotlib, a powerful and interactive plotting package. It is
capable of creating output files in several graphical formats, including EPS,
PDF, PS, PNG, and SVG.

Main features:

o Make plots interactively or using scripts
o Show grayscale, colorscale, and 3-color RGB images of FITS files
o Generate co-aligned FITS cubes to make 3-color RGB images
o Overlay any number of contour sets
o Overlay markers with fully customizable symbols
o Plot customizable shapes like circles, ellipses, and rectangles
o Overlay ds9 region files
o Overlay coordinate grids
o Show colorbars, scalebars, and beams
o Customize the appearance of labels and ticks
o Hide, show, and remove different contour and marker layers
o Pan, zoom, and save any view as a full publication-quality plot
o Save plots as EPS, PDF, PS, PNG, and SVG
