Iozone is a great tool to mesure performance of filesystem. You could find 10 examples here.
In it latest version, 3.97, it came with reporting tools, report.pl and gengnuplot.sh, who use gnuplot to render images.
Due to changes in GnuPlot 4.x, report.pl and gnu3d.dem need to be updated to works. Also you may get only 8 metrics in reports instead of 15 expected in latest release of report.pl
gnu3d.dem
#
# $Id: 3D plot of performance
#
# Processes files that were created by Generate_Graphs
# and displays the results. Also, saves a postscript copy.

#
# This script is based loosely on the Generate_Graph set
# of scripts that come with iozone, but is a complete re-write
#
# The main reason to write this was the need to compare the behaviour of
# two or more different setups, for tuning filesystems or
# comparing different pieces of hardware.
#
# This script is in the public domain, too short and too trivial
# to deserve a copyright.
#
# Simply run iozone like, for example, ./iozone -a -g 4G > config1.out (if your machine has 4GB)
# and then run perl report.pl config1.out
# or get another report from another box into config2.out and run
# perl report.pl config1.out config2.out
# the look in the report_* directory for .png
#
# If you don't like png or the graphic size, search for "set terminal" in this file and put whatever gnuplot
# terminal you want. Note I've also noticed that gnuplot switched the set terminal png syntax
# a while back, you might need "set terminal png small size 900,700"
