It looks like you want to use the x-axis for the hits and the y-axis for 
the users. As far as I know, this is not possible. You have to generate 
a "normal" gnuplot image first, then rotate it by 90 degrees, see below.

Hermann

$ cat tt.gp
set terminal png
set output "topten.png"
set style fill solid
set boxwidth 0.9 relative
set grid
set ylabel "Hits of top ten users (in 1000)"
set xtics rotate
set ytics rotate
set nokey
plot [:][0:] "topten.log" using ($1)/1000:xticlabels(2) with boxes

$ gnuplot tt.gp && convert topten.png -rotate 90 topten_rotated.png
