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.
