Robb -

I think the easiest way is to use error bars (appropriately formatted).

I've posted an example, ShadedNormalDensity.xls, on
http://www.mikemiddleton.com in the bottom left corner of the home page.

As I recall, another way is a combination chart using an XY (Scatter) series
and an Area series.

Looking to spice up my statistics home work. I've figured out how to
chart a
normal distribution curve using a scatter plot. How can I pick a point or
two points on the curve and shade between them to show an area?
