matplotlib.pyplot.set_loglevel(*args, **kwargs)[source]#

Set Matplotlib's root logger and root logger handler level, creating the handler if it does not exist yet.

Typically, one should call set_loglevel("info") or set_loglevel("debug") to get additional debugging information.

level{"notset", "debug", "info", "warning", "error", "critical"}

The log level of the handler.


The first time this function is called, an additional handler is attached to Matplotlib's root handler; this handler is reused every time and this function simply manipulates the logger and handler's level.
