# matplotlib.pyplot.rc_context

`matplotlib.pyplot.``rc_context`(rc=None, fname=None)

  Return a context manager for managing rc settings.

  This allows one to do:

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

  The ‘a’ vs ‘x’ and ‘c’ vs ‘x’ plots would have settings from ‘screen.rc’, while the ‘b’ vs ‘x’ plot would have settings from ‘print.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')
          plt.close(fig)
