here is the code I am using

set terminal png
set style fill   solid 1.00 border lt -1
set output "histcum.png"
set datafile missing "-"
set key below box vertical
set boxwidth 0.75 absolute
set key outside right top vertical Left reverse noenhanced autotitles columnhead nobox
set key invert samplen 4 spacing 1 width 0 height 0 
set style histogram rowstacked title  offset character 0, 0, 0
set style data histograms
set xtics border in scale 0,0 nomirror rotate by -45  offset character 0, 0, 0 norangelimit font ",8"
set title "My plot" 
set yrange [ 0.00000 : 20 ] noreverse nowriteback
set xlabel "X label"
set ylabel "Y Label"
i = 8
plot "histcum.txt" using 2:xticlabels(1), for [i=3:7] '' using i 

here is the result

as you can see the xscale is unreadable... any idea on how to print only one out of 10 for instance?

case closed.

data histograms cannot be used for such a plot in fact.

Printing every fifth label only would be rather easy in your case. Try

plot ... using 2:xticlabels(((int($1) % 500) == 100) ? stringcolumn(1) : "") ...
