I have a gnuplot script

set terminal qt size 850,500 enhanced font 'Verdana,12' persist
set boxwidth 0.9 absolute
set ylabel "Duration in milliseconds" #font "Arial 14"
set tics font "Monospaced,bold 14"
set style fill solid 1.00 border lt -1
set key inside right top vertical Right noreverse noenhanced autotitle nobox 
set style histogram cluster gap 1 title textcolor lt -1
set minussign
set datafile missing '-'
set style data histograms
set xtics border in scale 0,0 nomirror rotate by -45 autojustify
set xtics norangelimit
set xtics    ()
set title "Integer d-ary heap performance"
set yrange [0:*]
set style line 1 lt 1 lc rgb "#000000"
set style line 2 lt 2 lc rgb "green"
plot 'integer_heap_benchmark_dary.dat' using 2:xtic(1) linecolor rgb "#5555ff" title col, \
        '' using 3:xtic(1) linecolor rgb "#f4dc42" title col, \
        '' using 4:xtic(1) title col

which looks like this:

My histogram

What I want to achieve is:

  1. Move each x-axis label a little bit to the left so that it "points" to the center of each cluster,
  2. Change the font and size of the x-axis labels.

I have put an effort to find the answers on my own, yet without any success.

Try something like

set tics font "Courier,24"

to set the font.

To center the labels, try something like

set xtics offset -3

You'll have to experiment with the values.
