matplotlib.pyplot.rc_context(rc=None, fname=None)[source]

Return a context manager for managing rc settings.

This allows one to do:

with mpl.rc_context(fname='screen.rc'):
    plt.plot(x, a)  # uses 'screen.rc'
    with mpl.rc_context(fname='print.rc'):
        plt.plot(x, b)  # uses 'print.rc'
    plt.plot(x, c)  # uses 'screen.rc'

A dictionary can also be passed to the context manager:

with mpl.rc_context(rc={'text.usetex': True}, fname='screen.rc'):
    plt.plot(x, a)

The 'rc' dictionary takes precedence over the settings loaded from 'fname'. Passing a dictionary only is also valid. For example a common usage is:

with mpl.rc_context(rc={'interactive': False}):
    fig, ax = plt.subplots()
    ax.plot(range(3), range(3))
    fig.savefig('A.png', format='png')
