I tried posting this to the NetLogo user group on Yahoo but wasn't successful in getting the post accepted. So I'm trying here.
NetLogo can plot histograms. Is there any way to get access to the histogram data, i.e., the data generated for the histogram plot? Thanks.

I don't think it's possible to get the values. Though if you wanted to implement your own histogram for data, you could use something like:
to-report calc-histogram [ aList numBars aMaxValue ]
let minValue min aList
let interval (aMaxValue - minValue) / numBars
let hist 
foreach n-values numBars [?] [
let lowerBound minValue + (? * interval)
let upperBound lowerBound + interval
let x (lowerBound + upperBound) / 2
let y length filter [? >= lowerBound and ? < upperBound] aList
set hist lput (list x y ) hist
observer> calc-histogram [0 1 18 2 3 4 5 6 7 7 7 9 10 7 15 7 17 18 19 ] 5 20
observer: [[2 4] [6 8] [10 2] [14 1] [18 4]]
