I'm using 4.1 downloaded source and I love the new clustered histogram feature.  However, I cant figure out simply how to add errorbars... yerrorbars? boxerrorbars? is this possible?

snippet of my script:
set terminal postscript eps solid enhanced 14
set output "graph.eps"
set xtics nomirror
set ytics nomirror
set border 3
set key spacing 1.5
set title "Binding in vitro"
set auto x
set style data histogram
set style histogram cluster gap 1
set style fill pattern border -1
set boxwidth 0.9
set key left top
set ylabel "Fluorescence Intensity (au)"
plot 'flow.dat' using 2:xtic(1) title column fs pattern 0,\      'flow.dat' using 3 title column fs pattern 3,\      'flow.dat' using 4 title column fs pattern 5
