cfetoolgraph(8) - Linux man page

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.
