Ridgeline plots using seaborn

Based on the following seaborn gallery example:

Overlapping densities (‘ridge plot’) — seaborn 0.11.0 documentation

    def label_func(data, color, label):

        label = label_fmt.format(x=label)
        ax.text(0, 0, label, ha='left', va='bottom', transform=ax.transAxes)
    
    with sns.axes_style(style='white', rc={'axes.facecolor': (0, 0, 0, 0)}):
        g = sns.FacetGrid(df, row=row, hue=hue, height=height, aspect=aspect)
        g.map_dataframe(map_func, x=x, fill=fill, lw=lw, alpha=alpha, **map_kwargs)
