Tatsuo previously posted a script to extract a gnuplot-ready data file
from a transcript of a set of pgbench runs. I've been using that, plus
gnuplot scripts like the following (slightly tweaked from Tatsuo's
example):

set xlabel "concurrent users"
set ylabel "TPS"
set yrange [150:330]
set logscale x
set key width 5
set key right

plot \
'bench.try2-noassert.data' title 'select spins 100' with linespoint lw 4 pt 1 ps 4, \
'bench.try2-na-s1000.data' title 'select spins 1000' with linespoint lw 4 pt 2 ps 4, \
'bench.try2-na-s10000-2.data' title 'select spins 10000' with linespoint lw 4 pt 3 ps 4, \
'bench.yield-s100-2.data' title 'yield spins 100' with linespoint lw 4 pt 4 ps 4, \
'bench.yield-s1000-2.data' title 'yield spins 1000' with linespoint lw 4 pt 5 ps 4
