I am using Excel 2003 to graph data over distances of 10 to 15 thousand feet.
The page sizes offered are so small that changes in the data over this range
are difficult to detect.

Is there a way to make a custom page size that is roughly 12 inches tall
with the potential to be infinately long. This way, all the data wouldn't be
crowded into a limited area, and a person could scroll left or right along
the data interval.
