Some -- but not all -- characteristics of matplotlib plots can be configured via the matplotlib.rcParams dictionary.
Add a new matplotlibrc file to the rc dir, say myrc, and use:
$ ./showstyle.py myrc
See the showstyle.py file for usage -- for example, note how hist and scatter grab the first color in rcParams['axes.color_cycle'] since there's no way to set the default scatter or hist color via rcParams.
Some included styles are:
- default
- ggplotish
- probpro
- rlike
