Gnuplot script to plot TIMING-SA values from amavis maillogs

#!/usr/bin/env gnuplot
# Extract the values into a csv, I tend to save only hour:minutes:seconds and the milliseconds using awk
# Example: grep TIMING-SA /var/log/maillog | awk '{printf "%s,%s\n", $3, $11}'
#
# Then set the csv filename in envrionment before running script. 
# export GNUPLOT_NAME=sa_timing.csv
# ./gnuplot.gnu
