        Plot spectrogram onto figure.

        Parameters
        ----------
        figure : `~matplotlib.Figure`
            Figure to plot the spectrogram on. If None, new Figure is created.
        overlays : list
            List of overlays (functions that receive figure and axes and return
            new ones) to be applied after drawing.
        colorbar : bool
            Flag that determines whether or not to draw a colorbar. If existing
            figure is passed, it is attempted to overdraw old colorbar.
        vmin : float
            Clip intensities lower than vmin before drawing.
        vmax : float
            Clip intensities higher than vmax before drawing.
        linear : bool
            If set to True, "stretch" image to make frequency axis linear.
        showz : bool
            If set to True, the value of the pixel that is hovered with the
            mouse is shown in the bottom right corner.
        yres : int or None
            To be used in combination with linear=True. If None, sample the
            image with half the minimum frequency delta. Else, sample the
            image to be at most yres pixels in vertical dimension. Defaults
            to 1080 because that's a common screen size.
        max_dist : float or None
            If not None, mask elements that are further than max_dist away
            from actual data points (ie, frequencies that actually have data
            from the receiver and are not just nearest-neighbour interpolated).

        After being called on a properly initialised instance of a Wavescape object,
        this method draws the visual plot known as "wavescape" and generate a 
        matplotlib.pyplot figure of it. This means any of the method from this
        library can be used after this method has been called in order to
        save or alter the figure produced. 

        Parameters
        ----------
        
        ax: matplotlib figure, optional
            if provided, will draw the wavescape on it. Useful if many wavescapes need to
            be drawn in the same figure, or if the plot needs to be combined to others.
            Default value is None.
        
        aw_per_tick: numeric value, optional
            Ratio of tick per elements of the lowest level in the wavescape. If aw_per_tick has value 1,
            one horizontal axis tick will be drawn per element at the lowest hierarchical level of the wavescape, 
            if it has value 2, then a tick will be drawn each two elements and so forth. For the ticks to represent the bar numbers,
            a pre-existing knowledge of the time signature of the musical piece is required. (for instance, if a piece is in 4/4,
            and the analysis window has a size of one quarter note, then aw_per_tick needs to have value 4 for the
            ticks to correspond to bar numbers)
            Default value is None (meaning no ticks are drawn)
            
        tick_offset: int, optional
            offset value for the tick drawn according to the 'aw_per_tick' parameter. This is done
            so that musical pieces with 0th measure can have tick accurately representing the source
            material's bar numbers. Like the tick ratio, this number is relative to the analysis window's
            size and requires a pre-existing knowledge of the score.
            Its value must be higher or equal to 0 but strictly lower than aw_per_tick.
            If it has value "0", the first tick of the plot will be set to the value of 1. 
            For having the first tick of the plot set to the value of 0, leave that parameter to
            None and have a coherent value for aw_per_tick
            Default value is 0 (meaning no tick offset). 
        
        tick_start: int, optional
            Indicates at which number to start the tick numbering. We recommand, for
            classical score, to put the value "1", as most scores starts numbering their bars
            with 1 instead of 0.
            Default value is 0.
        
        tick_factor: float, optional
            Multiply the major ticks numbers displayed on the x-axis by a constant.
            Can be useful for very large pieces, where displaying a single tick on each
            bottom row element would make the x-axis hard to read. By increasing the aw_per_tick,
            and giving this parameter a certain value, it is possible to display less ticks while 
            still keeping the right indicative numbers with respect to the unit system chosen. 
            Default value is 1.0, (meaning the value displayed is consistent with the number of ticks, with 
            respect to tick_offset of course.)
        
        subparts_highlighted: tuple of numeric values, OR array of tuples of numeric values, optional
            List of subsections that needs to be highlighted with black outlines on the wavescape. Units
            are expressed in number of analysis windows. For example, if a musical piece has a 4/4 
            time signature, an analysis window of 1 quarter note and a total of 10 bars, the
            value [[20,28],[32,36]] for 'subparts_highlighted' will draw black outlines on the region
            of the wavescape corresponding to bars 5 until 7 and 8 until 9. 
            This parameter is interpreted differently if it has the shape of a single tuple. In such case,
            a subpplot corresponding to the delimitation in the tuple will be drawn instead. For instance,
            'subparts_highlighted=[20,28]' will only draw the wavescape corresponding to piece from bar
            5 to 7 (if the musical piece is in 4/4). Be careful not to write 'subparts_highlighted=[[20,28]]' 
            which is interpreted as drawing a highlight of bar 5 to 7 on the full wavescape.
            Default value is None (meaning no highlighting and no subsection of wavescape drawn)

        indicator_size: float, optional 
            Determine the factor by which to increment the size of the rounded indicators on the lateral edges of the plot that need. 
            A rounded indicator is drawn at each eight of the height of the plot if a value is provided for this argument.
            Enter the value "1.0" for the default size.
            Default value is None (meaning no vertical indicators)
        
        add_line: numeric value, optional
            if provided, this parameter represents the thickness of the black line outlining
            all element of the plot (drawing primitives).
            Default value is None.
        
        label: str, optional
            If provided, add this string as a textual label on the top left corner of the resulting plot.
            Can be used to specify the Fourier coefficient visualised on the wavescape for example.
            Default value is None
            
        label_size: float, optional
            Determine the size of the top-left label and the tick number labels if provided
            Default value is None (in which case the default 
            size of the labels is the width of the plot divided by 30)

        Returns
        -------
        Nothing, but a matplotlib.pyplot figure is produced by this method, and any method of pyplot
        can be used to alter the resulting figure (notably matplotlib.pyplot.savefig can be used to save the
        resulting figure in a file)
