Ubuntu Manpage: battery-graph - Show a graph of the battery charge

NAME

       battery-graph - Show a graph of the battery charge

SYNOPSIS

       battery-graph [options] [files...]

DESCRIPTION

       Show a graph of the battery charge over time.

       The files given are assumed to contain battery statistics in the battery-stats(5) format. If no files are
       specified, the default log files will be used.

       The  options  can  be used for displaying a different interval. An interval is defined in terms of a from
       timestamp, a to timestamp  and  a  duration.  By  specifying  any  two,  the  third  will  be  calculated
       automatically. A missing duration will be defaulted to 3 hours.

OPTIONS

These programs follow the usual GNU command line syntax, with long options starting with two dashes
(`-').

-g geometry, --geometry geometry
Sets the X Windows geometry of the graph. This disables text mode. See X(7) for how to specify the
geometry.

-D display, --display display
Shows the graph on the given display. The same effect can be achieved by setting the DISPLAY
environment variable. This disables text mode. See X(7) for valid values.

--title string
Sets the title of the graph window. By default this will be "Battery Graph". If this is set to the
empty string, gnuplot(1) will be allowed set the window title - this can be useful if you want
your ~/.Xdefaults to take effect for this.

-f date, --from date
Specifies the start date/time for the graph. This accepts exactly the same date/time
specifications as the date (1) command - see examples below or the Texinfo manual for date for
details.

-t date, --to date
Specifies the ending date/time for the graph. This accepts exactly the same date/time
specifications as the date (1) command - see examples below or the Texinfo manual for date for
details.

-s date, --since date
Shorthand for --from date --to now

-d duration, --duration duration
Specifies the duration for the graph. This can be given in units of seconds, hours, days or weeks
by suffixing the number with 's' (seconds), 'm' (minutes), 'h' (hours), 'd' (days) or 'w' (weeks).
Units cannot be combined - e.g. '1d6h' will not be valid, whereas '30h' is OK. If no unit is
specified, minutes will be assumed.

--text Shows the graph in text mode on stdout. The resulting size of the graph is determined by the
values of the environment variables. LINES and COLUMNS (failing that, the output from tput will
be used). This is the default when the environment variable DISPLAY is not set.

EXAMPLES

       Show the last 2 hours:
              $ battery-graph --duration 2h

       Show the time since mid day:
              $ battery-graph --from 12:00 --to now
              or
              $ battery-graph --since 12:00

       Show the hour before last:
              $ battery-graph --from '2 hours ago' --duration 1h

       Show the 6 hours after noon:
              $ battery-graph --from 12:00 --duration 6h
              or
              $ battery-graph --from 12:00 --to 18:00

       Show the last 6 hours
              $ battery-graph --from '6 hours ago'
              or
              $ battery-graph --since '6 hours ago'

       Show the last 30 minutes in text mode:
              $ battery-graph --duration 30 --text

       Show statistics for Tuesday last week
              $ battery-graph --duration 24h --from 'tuesday last week'
              or
              $ battery-graph --duration 1d --from 'tuesday last week'

       Prove that the future hasn't happened yet:
              $ battery-graph --from yesterday --to tomorrow

       Another way of wasting CPU cycles:
              $ battery-graph /dev/null

EXIT STATUS

       battery-graph depends on gnuplot (1) to give the correct exit status.

FILES

       If no files are given on the command line, batter-graph reads from /var/log/battery-stats

ENVIRONMENT

       DISPLAY
              If this variable is not set, --text will be defaulted.

       LINES / COLUMNS
              Determines the size of the graph in text mode.

DIAGNOSTICS

       If there are no statistics available for the period chosen, an empty graph will result.

NOTES

       There is no requirement for the from time to be earlier than the to time - if so,  the  X  axis  will  be
       reversed. Similar results can be achieved using a negative duration.

       Also: battery-stat is quite happy to list statistics in the future; stupid, but obedient.
