@Chunru Thanks, what if I want to compute the confidence interval (0.05 and 0.95). How I can do in case of above attached data?
I want to plot uncertainty represented by the area between the 10th percentile and the 90th percentile is given in gray. How can do it by using above percentile?

I don't know how your data can be interpreted. Can you elaborate more?
