cfetoolgraph - create graphs from a cfetool database


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


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.


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


   % cfetoolgraph temperature --path /my/path --resolution

Create graph files of the weekly database in high resolution in the "/my/path/temperature/weekly-snapshot" directory.
