matplotlib.pyplot.close

matplotlib.pyplot.close(fig=None)[source]

Close a figure window, and unregister it from pyplot.

Parameters:

figNone or int or str or Figure

The figure to close. There are a number of ways to specify this:

• None: the current figure
• Figure: the given Figure instance
• int: a figure number
• str: a figure name
• 'all': all figures

Notes

pyplot maintains a reference to figures created with figure(). When work on the figure is completed, it should be closed, i.e. deregistered from pyplot, to free its memory (see also :rc:figure.max_open_warning). Closing a figure window created by show() automatically deregisters the figure. For all other use cases, most prominently savefig() without show(), the figure must be deregistered explicitly using close().
