Hi Dave,

My IDL is a little rusty. The crude example below should give you the
idea behind the reverse indices and how to access the values in your
bins.

Cheers.

z = randomn(7, 100) + findgen(100)/20.

hist = histogram(z, max =5., min = 0., binsize = 1., reverse_indices =
r)

bin1 = r[r[0]:r[1] - 1]
bin2 = r[r[1]:r[2] - 1]
bin3 = r[r[2]:r[3] - 1]
bin4 = r[r[3]:r[4] - 1]
bin5 = r[r[4]:r[5] - 1]

results = fltarr(5)

results(0) = mean(z[bin1])
results(1) = mean(z[bin2])
results(2) = mean(z[bin3])
results(3) = mean(z[bin4])
results(4) = mean(z[bin5])

plot, findgen(100)/20, z
oplot, findgen(5) + 0.5, results, psym = 2
