Shaded area under a curve 2

I am currently devising an excel spreadsheet containg a graph of the data, is there a way to shade the area above (or below) the curve in a different colour?

An area chart (under standard types) may give you what you want.
 
I've been wanting to be able to do that for a long time! Thanks for the great link... star for Panars
 
I don't think that an area chart would suit, the problem is that my chart has two curves:
The Y axis shows positive values and negative values. The Y axis runs from -5 to +5 with the x axis starting at zero on the Y axis. X axis values run from 0 to 200. I have plotted two curves - one is a positive curve and the other a negative curve. These two curves start at 0,0 and diverge as X increases. I want to shade the areas outside the part of the chart contained by the two curves.
These two curves show the limits of acceptability for a calibration sequence that will be plotted manually on a printed version of the chart. I want to show graphically that if any (manually) plotted point is in the area outside the two curves then that value will show an unacceptable condition.
 
The standard Excel area chart won't work, but check out the website that Panars posted--it shows how to fake this for an X-Y plot. The page for doing area between two curves is here:
It looks like it's actually easier to show the area outside the curves than the area between them.
