| Default Values & Styling |
class matplotlib.RcParams(*args, **kwargs) | A dictionary object including validation. Validating functions are defined and associated with rc parameters in matplotlib.rcsetup. |

| matplotlib.rc_context(rc=None, fname=None) | Return a context manager for temporarily changing rcParams. | |
| matplotlib.rc(group, **kwargs) | Set the current rcParams. group is the grouping for the rc, e.g., for lines.linewidth the group is lines, for axes.facecolor, the group is axes, and so on. Group may also be a list or tuple of group names, e.g., (xtick, ytick). kwargs is a dictionary attribute name/value pairs. | |
| matplotlib.rcdefaults() | Restore the rcParams from Matplotlib's internal default style. Style-blacklisted rcParams (defined in matplotlib.style.core.STYLE_BLACKLIST) are not updated. |
|
