The cfetoolgraph command dumps graphs of averages for visual inspection of the
normal state database. The files are in a format viewable by gnuplot or
xgmr or other graphical plotting program.
The command generates three or four files in a subdirectory of the database
directory with a name beginning with either daily, weekly or yearly,
then -, then either snapshot or the current time, if the -T option is
used. The files are named average, stddev, and graph. The graph
file contains both the averages and standard deviations, useful for plotting
with error bars.
If a histogram file is present, a fourth file named distr will also be
created, plotting the distribution of fluctuations about the mean value.
If the -d, -w and -y options are all omitted, the default is to only
graph the weekly database.
