 """Plot a folded scaled site frequency spectrum. Parameters s : array_like, int, shape (n_chromosomes/2,) Site frequency spectrum. yscale : string, optional Y axis scale. bins : int or array_like, int, optional Allele count bins. n : int, optional Number of chromosomes sampled. If provided, X axis will be plotted as allele frequency, otherwise as allele count. clip_endpoints : bool, optional If True, do not plot first and last values from frequency spectrum. label : string, optional Label for data series in plot. plot_kwargs : dict-like Additional keyword arguments, passed through to ax.plot(). ax : axes, optional Axes on which to draw. If not provided, a new figure will be created. Returns ------- ax : axes The axes on which the plot was drawn. """
