+            include_coverage_residual (bool, optional): Whether to include the residual plot (coverage fraction - diagonal). Creates an additional subplot under the original plot. Defaults to False.
+            include_coverage_residual_std (bool, optional): Whether to include the standard deviation shading for residuals. Defaults to False.
+            include_ideal_range (bool, optional): Whether to include the ideal range shading (0.1/0.2 around the diagonal). Defaults to True.
             reference_line_label (str, optional): Label name for the diagonal ideal line. Defaults to "Reference Line".
             reference_line_style (str, optional): Line style for the reference line. Defaults to "k--".
             x_label (str, optional): y label. Defaults to "Confidence Interval of the Posterior Volume".
