def subplot2grid(shape, loc, rowspan=1, colspan=1, fig=None, **kwargs):
    """
    Create an axis at specific location inside a regular grid.

    Parameters
    ----------
    shape : sequence of 2 ints
        Shape of grid in which to place axis.
        First entry is number of rows, second entry is number of columns.

    loc : sequence of 2 ints
        Location to place axis within grid.
        First entry is row number, second entry is column number.

    rowspan : int
        Number of rows for the axis to span to the right.

    colspan : int
        Number of columns for the axis to span downwards.

    fig : `Figure`, optional
        Figure to place axis in. Defaults to current figure.

    **kwargs
        Additional keyword arguments are handed to `add_subplot`.


    Notes
    -----
    The following call ::

    is identical to ::
