Thank you!!

We can shade the graphs by adding these two commands after fill operation.

Thank you for your contribution ! You saved me a lot of search time. I only have one suggestion to improve your function : you could add a new input argument to control the "EdgeColor" of the CI to avoid using the default edge color.

Great Work

I could get two sets of bands on the same graph by just defining upper and lower each as two column matrices. But somehow I just can't get them in different shades. Any advice?

Nice, but ...

How do you get the transparent overlays that you've got in the example?
