Data Visualization (`astropy.visualization`)
********************************************
Introduction
============
`astropy.visualization` provides functionality that can be helpful when
visualizing data. This includes a framework for plotting Astronomical images
with coordinates with Matplotlib (previously the standalone **wcsaxes**
package), functionality related to image normalization (including both scaling
and stretching), smart histogram plotting, RGB color image creation from
separate images, and custom plotting styles for Matplotlib.

Scripts
=======
This module includes a command-line script, ``fits2bitmap`` to convert FITS
images to bitmaps, including scaling and stretching of the image. To find out
more about the available options and how to use it, type::
$ fits2bitmap --help
.. note that if this section gets too long, it should be moved to a separate
doc page - see the top of performance.inc.rst for the instructions on how to do
that
