        '''
        Method that plots abundence chart and saves those figures to a
        .png file (by default). Plots a figure for each cycle in the
        argument cycle.

        Parameters
        ----------
        cyclist : list
            The list of cycles we are plotting.
        mass_range : list, optional
            A 1x2 array containing the lower and upper mass range.  If
            this is an instance of abu_vector this will only plot
            isotopes that have an atomic mass within this range.  This
            will throw an error if this range does not make sence ie
            [45,2] if None, it will plot over the entire range.  The
            default is None.
        ilabel : boolean, optional
            Elemental labels off/on.  The default is True.
        imlabel : boolean, optional
            Label for isotopic masses off/on.  The efault is True.
        imlabel_fontsize : intager, optional
            Fontsize for isotopic mass labels.  The default is 8.
        imagic : boolean, optional
            Turn lines for magic numbers off/on.  The default is False.
        boxstable : boolean, optional
            Plot the black boxes around the stable elements.  The
            default is True.
        lbound : tuple, optional
            Boundaries for colour spectrum ploted.  The defaults is 20.
        plotaxis : list, optional
            Set axis limit: If [0,0,0,0] the complete range in (N,Z)
            will be plotted.  The default is [0,0,0,0].
        color_map : string, optional
            Color map according to choices in matplotlib
            (e.g. www.scipy.org/Cookbook/Matplotlib/Show_colormaps).
            The default is 'jet'.
        pdf : boolean, optional
            What format will this be saved in pdf/png.  The default is
            True.
        title : string, optional
            The title of the plots and the saved images.  The default is
            None.
