================================================================
Demo of the histogram function's different ``histtype`` settings
================================================================

* Histogram with step curve that has a color fill.
* Histogram with custom and unequal bin widths.

Selecting different bin counts and sizes can significantly affect the
shape of a histogram. The Astropy docs have a great section on how to
select these parameters:
