How do you create a colored probability range around a graph line

[Caerus]

I am looking to add a probability range around an established line in an
excel chart. Ideally I would like to link the error bars and create a
colored area.

Hi,

You can adapt Jon Peltier's explanation of shading between lines to
shade an area around the line.
