Fernando Cinquegrani (http://www.prodomosua.it/ppage02.html) has some very creative
charting utilities on his web site, including some contour charts. It's in Italian,
but you could translate the page using babelfish.com or one of the other services.

I have created elevation profiles of state park trails that I have GPSed.
The X is distance in miles, the Y is elevation in feet, plotted on a scatter
chart (the locations of the GPS points is not uniform). I would like to show
the areas of the trail that exceed a particular slope in a different color.
I suspect I would have to create a new data series that includes just those
areas and then add it to the chart. How do I determine which areas meet the
criteria I set forth?
