def new_figure(fig_width, fig_height, size_in_cm=True, style=None, no_backend=False, quiet=False, **kwargs):
    """
    Return a new matplotlib figure of the specified size (in cm by default)

    Information about the matplotlib backend, settings and the figure will be
    printed on STDOUT, unless `quiet=True` is given.

    The remaining kwargs are passed to the Figure init routine

    Arguments
    ---------

    fig_width: float
        total width of figure canvas, in cm (or inches if `size_in_cm=False`

    fig_height: float
        total height of figure canvas, in cm (or inches if `size_in_cm=False`

    size_in_cm: boolean, optional
        give as False to indicate that `fig_width` and `fig_height` are in
        inches instead of cm

    style: string or array of strings, optional
        A style file to overwrite or ammend the matplotlibrc file. For
        matplotlib version >=1.4, the style sheet feature will be used, see
        <http://matplotlib.org/users/style_sheets.html>
        In older versions of matplotlib, `style` must a filename or URL string;
        the contents of the file will be merged with the matplotlibrc settings

    no_backend: boolean, optional
        If given as True, skip the use of the pyplot entirely, creating the
        figure in a purely object-oriented way.

    quiet: boolean, optional

    Notes
    -----

    You may use the figure as follows, assuming the pyplot is used
    (`no_backend=False`)

    >>> import matplotlib
    >>> matplotlib.use('PDF') # backend ('PDF' for pdf, 'Agg' for png)
    >>> fig = mgplottools.mpl.new_figure(10, 4)
    >>> pos = [0.05, 0.05, 0.9, 0.9] # left, bottom offset, width, height
    >>> ax = fig.add_axes(pos)
    >>> ax.plot(linspace(0, 10, 100), linspace(0, 10, 100))
    >>> fig.savefig('out.pdf', format='pdf')

    Alternatively, for a GUI backend, instead of `fig.savefig()`, you can
    display all created figures using `fig.show()` -- it is set up as an alias
    to matplotlib.pyplot.show().

    If you want to do any interactive plotting in ipython (i.e. manipulating
    the plot after its creation), make sure to load the %matplotlib or %pylab
    magic functions. Also, you must use pyplot

    >>> import matplotlib.pyplot as plt

    Do not use `plt.ion()`, which does not work in ipython.
    Simply create a figure, then call `plt.show()` and `plt.draw()`

    If not using a backend (`no_backend=True`, bypassing the pyplot state
    machine), you must create the canvas manually. Consider using the
    `show_fig`, `write_pdf`, `write_eps`, and `write_png` routines

    Produces a figure of an estimation result.

    The figure consists of the original data, in the Fourier domain, along
    with each oscillator.

    Parameters
    ----------
    data : numpy.ndarray
        Data of interest (in the time-domain).

    result : numpy.ndarray
        Parameter estimate, of form:

        * **1-dimensional data:**

          .. code:: python3

             parameters = numpy.array([
                [a_1, φ_1, f_1, η_1],
                [a_2, φ_2, f_2, η_2],
                ...,
                [a_m, φ_m, f_m, η_m],
             ])

        * **2-dimensional data:**

          .. code:: python3

             parameters = numpy.array([
                [a_1, φ_1, f1_1, f2_1, η1_1, η2_1],
                [a_2, φ_2, f1_2, f2_2, η1_2, η2_2],
                ...,
                [a_m, φ_m, f1_m, f2_m, η1_m, η2_m],
             ])

    sw : [float] or [float, float]
        Sweep width in each dimension (Hz).

    offset : [float] or [float, float]
        Transmitter offset in each dimension (Hz).

    sfo : [float, [float, float] or None, default: None
        Transmitter frequency in each dimnesion (MHz). Needed to plot the
        chemical shift axis in ppm. If `None`, chemical shifts will be plotted
        in Hz.

    nucleus : [str], [str, str] or None, default: None
        The nucleus in each dimension.

    region : [[int, int]], [[float, float]], [[int, int], [int, int]] or \
    [[float, float], [float, float]]
        Boundaries specifying the region to show. See also
        :py:class:`nmrespy.freqfilter.FrequencyFilter`.

    plot_residual : bool, default: True
        If `True`, plot a difference between the FT of `data` and the FT of
        the model generated using `result`. NB the residual is plotted
        regardless of `plot_residual`. `plot_residual` specifies the alpha
        transparency of the plot line (1 for `True`, 0 for `False`)

    residual_shift : float or None, default: None
        Specifies a translation of the residual plot along the y-axis. If
        `None`, the default shift will be applied.

    plot_model : bool, default: False
        If `True`, plot the FT of the model generated using `result`.
        NB the residual is plotted regardless of `plot_model`. `plot_model`
        specifies the alpha transparency of the plot line (1 for `True`,
        0 for `False`)

    model_shift : float or None, default: None
        Specifies a translation of the residual plot along the y-axis. If
        `None`, the default shift will be applied.

    data_color : matplotlib color, default: '#000000'
        The colour used to plot the original data. Any value that is
        recognised by matplotlib as a color is permitted. See
        `<here https://matplotlib.org/3.1.0/tutorials/colors/\
        colors.html>`_ for a full description of valid values.

    residual_color : matplotlib color, default: '#808080'
        The colour used to plot the residual.

    model_color : matplotlib color, default: '#808080'
        The colour used to plot the model.

    oscillator_colors : {matplotlib color, matplotlib colormap name, \
    list, numpy.ndarray, None}, default: None
        Describes how to color individual oscillators. The following
        is a complete list of options:

        * If a valid matplotlib color is given, all oscillators will
          be given this color.
        * If a string corresponding to a matplotlib colormap is given,
          the oscillators will be consecutively shaded by linear increments
          of this colormap. For all valid colormaps, see
          `<here https://matplotlib.org/stable/tutorials/colors/\
          colormaps.html>`__
        * If a list or NumPy array containing valid matplotlib colors is
          given, these colors will be cycled.
          For example, if ``oscillator_colors = ['r', 'g', 'b']``:

          + Oscillators 1, 4, 7, ... would be :red:`red (#FF0000)`
          + Oscillators 2, 5, 8, ... would be :green:`green (#008000)`
          + Oscillators 3, 6, 9, ... would be :blue:`blue (#0000FF)`

        * If `None`:

          + If a stylesheet is specified, with the attribute
            ``axes.prop_cycle`` provided, this colour cycle will be used.
          + Otherwise, the default colouring method will be applied,
            which involves cycling through the following colors:

            - :oscblue:`#1063E0`
            - :oscorange:`#EB9310`
            - :oscgreen:`#2BB539`
            - :oscred:`#D4200C`

    labels : Bool, default: True
        If `True`, each oscillator will be given a numerical label
        in the plot, if `False`, no labels will be produced.

    stylesheet : str or None, default: None
        The name of/path to a matplotlib stylesheet for further
        customaisation of the plot. See `<here https://matplotlib.org/\
        stable/tutorials/introductory/customizing.html>`__ for more
        information on stylesheets.

    Returns
    -------
    plot : :py:class:`NmrespyPlot`
        A class instance with the following attributes:

        * fig : `matplotlib.figure.Figure <https://matplotlib.org/3.3.1/\
        api/_as_gen/matplotlib.figure.Figure.html>`_
            The resulting figure.
        * ax : `matplotlib.axes.Axes <https://matplotlib.org/3.3.1/api/\
        axes_api.html#matplotlib.axes.Axes>`_
            The resulting set of axes.
        * lines : dict
            A dictionary containing a series of
            `matplotlib.lines.Line2D <https://matplotlib.org/3.3.1/\
            api/_as_gen/matplotlib.lines.Line2D.html>`_
            instances. The data plot is given the key `0`, and the
            individual oscillator plots are given the keys `1`,
            `2`, `3`, ..., `<M>` where `<M>` is the number of
            oscillators in the parameter estimate.
        * labels : dict
            A dictionary containing a series of
            of `matplotlib.text.Text <https://matplotlib.org/3.1.1/\
            api/text_api.html#matplotlib.text.Text>`_ instances, with the
            keys `1`, `2`, etc. The Boolean argument `labels` affects the
            alpha transparency of the labels:

            + `True` sets alpha to 1 (making the labels visible)
            + `False` sets alpha to 0 (making the labels invisible)
