I have 3 Plots over the same x-axis range: p1, p2, p3 Each plot is of a well-behaved monotonically decreasing function. The result of Show[p1,p2,p3] is three curves which do not intersect, with the exception except that the lower two curves intersect at x=0. I would like to fill in the region between the two lower curves with a Gray background. How can I accomplish this? regards, alan
