#----------------------------------------------------------------------

# This is a gnuplot script to generate a basic statistics information
# for data structures used in CPSC 223.  This script requires an
# "out.dat" file, which was generated by running:
#
#     ./hw6perf 6 > out.dat
#
# To run this script type the following at the command line
#
#     gnuplot -c plot_script.gp infile testname outfile
#
# For example, to create the output for HW-6, run
# the following from the command line
#
#     gnuplot -c plot_script.gp "out.dat" "Average Chain Length" "avg-chain-len.png"
