NAME

cfetoolgraph - create graphs from a cfetool database

SYNOPSIS

cfetoolgraph name [--path⎪-p directory name] [--daily⎪-d] [--weekly⎪-w] [--yearly⎪-y] [--timestamps⎪-T] [--resolution⎪-r] [--help⎪-h]

DESCRIPTION

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 graphi‐ cal 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 "snap‐ shot" or the current time, if the -T option is used. The files are named "average", "std‐ dev", 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.

OPTIONS

--path⎪-p directory name The directory in which the database specified by name can be found. --daily⎪-d Graph the daily averages database. --weekly⎪-w Graph the weekly averages database. --yearly⎪-y Graph the yearly averages database. --timestamps⎪-T Time-stamp the output filenames with the current time, in order to give a unique name. --resolution⎪-r Generate high resolution data (), instead of averaging data over periods of one hour to generate simpler and smoother graphs. --help⎪-h Prints a short help message and then exits.

EXAMPLE

% cfetoolgraph temperature --path /my/path --resolution Create graph files of the weekly database in high resolution in the "/my/path/tempera‐ ture/weekly-snapshot" directory.
