cfetoolgraph

CFETOOLGRAPH(8) 					User Contributed Perl Documentation					   CFETOOLGRAPH(8)

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 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.

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/temperature/weekly-snapshot" directory.
