I'd like to be able to set up zones in an Excel chart. Imagine a bell
curve.
Areas under the curve within one standard deviation could be green, those
between one and two standard deviations would be yellow, and those more
than
two would be red. Or I can have an X - Y scatter chart. If the X-axis
runs
from 0 - 10, I might want 0 - 3 as red, 3 - 5 as green, and 5 - 10 blue.
Just as an example.
