If you're in a unixy environment, first process your data using shell commands:

sort particles.dat | uniq -c > pcount.dat


Then (derived from
http://www.dcs.bbk.ac.uk/~gzoum01/howtos/gnuplot_barcharts.html), in
gnuplot:

gnuplot> set boxwidth 1 relative
gnuplot> set style data histograms
gnuplot> set style fill solid 1.0 border -1
gnuplot> plot [][0:] "pcount.dat" using 1:xticlabels(2)
