Bringfried,

I do this all the time and histogram is definitely the correct way. I
find that I have to reread the horrors of histogram often (although
less often lately, maybe I am learning). http://www.dfanning.com/tips/histogram_tutorial.html

The basic idea is that you have to setup histogram to have bins where
you want them then pull the indices out with reverse_indices.

I have a few to many things this second to make an example but in sudo
code it is like this (for me)

;; get the data
;; run histogram on the data
hi = histogram(data, binzise=0.4, min=1, reverse_indices=ri)
for i=0l, n_elements(hi)-1 do begin
;; do the reverse indices magic to get the right indices
;; do whatever computation and store it somewhere
endfor

Cheers,

Brian
