matplotlib.pyplot.set_loglevel#

matplotlib.pyplot.set_loglevel(level)[source]#

Configure Matplotlib's logging levels.

Matplotlib uses the standard library logging framework under the root logger 'matplotlib'. This is a helper function to:

• set Matplotlib's root logger level

• set the root logger handler's 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.

Users or applications that are installing their own logging handlers may want to directly manipulate logging.getLogger('matplotlib') rather than use this function.

Parameters:

level{"NOTSET", "DEBUG", "INFO", "WARNING", "ERROR", "CRITICAL"}

The log level as defined in Python logging levels.

For backwards compatibility, the levels are case-insensitive, but the capitalized version is preferred in analogy to logging.Logger.setLevel.

Notes

Note

This is equivalent to matplotlib.set_loglevel.

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.
