obs_median_size: size for median observation line
obs_ci_fill: color for observation CI fill
obs_ci_color: color for observation CI lines
obs_ci_linetype: linetype for observation CI lines
obs_ci_size: size for observations CI lines
sim_pi_fill: fill color for simulated prediction interval areas
sim_pi_alpha: transparency for simulated prediction interval areas
sim_pi_color: color for simulated prediction interval lines
sim_pi_linetype: linetype for simulated prediction interval lines
sim_pi_size: size for simulated prediction interval lines
sim_median_fill: fill color for simulated median area
sim_median_alpha: transparency for simulated median area
sim_median_color: color for simulated median line
sim_median_linetype: linetype for simulated median line
sim_median_size: size for simulated median line
bin_separators_color: color for bin separator lines, NA for don't plot
