def set_context(context=None, font_scale=1, rc=None):
    """Set the plotting context parameters.
    This affects things like the size of the labels, lines, and other
    elements of the plot, but not the overall style. The base context
    is "notebook", and the other contexts are "paper", "talk", and "poster",
    which are version of the notebook parameters scaled by .8, 1.3, and 1.6,
    respectively.
    Parameters
    ----------
    context : dict, None, or one of {paper, notebook, talk, poster}
        A dictionary of parameters or the name of a preconfigured set.
    font_scale : float, optional
        Separate scaling factor to independently scale the size of the
        font elements.
    rc : dict, optional
        Parameter mappings to override the values in the preset seaborn
        context dictionaries. This only updates parameters that are
        considered part of the context definition.
    Examples
    --------
    >>> set_context("paper")
    >>> set_context("talk", font_scale=1.4)
    >>> set_context("talk", rc={"lines.linewidth": 2})

    --------
    plotting_context : return a dictionary of rc parameters, or use in
                       a ``with`` statement to temporarily set the context.
    set_style : set the default parameters for figure style
    set_palette : set the default color palette for figures
