       stripchart - draws diagrams from data with PHP


       The script is expected to be called as a CGI script but also works from the command line.


       Stripchart  prepares  a  series  of  diagrams directly from raw data.  It is handy for web
       pages that need some graphics without too much overhead.


       -i input FILE
              name of input data file (mandatory)

       -o output FILE
              name of output .gif file (default: STDOUT)

       -O output FILE
              name of output .gif file, also dumps to STDOUT

       -f from TIME
              stripchart with data starting at TIME (default: 24 hours ago)

       -t to TIME
              stripchart with data ending at TIME (default: now)

       -r range RANGE
              stripchart data centered around "from" time the size of RANGE (overrides -t)

       -l last LINES
              stripchart last number of LINES in data file (overrides -f and -t and -r)

       -T title TITLE
              title to put on graphic (default: FILE RANGE)

       -x column X
              time or "x" column (default: 2)

       -y column Y
              value or "y" column (default: 3)

       -Y column Y'
              overplot second "y" column (default: none)

       -b baseline VALUE
              overplot baseline of arbitrary value VALUE

       -B baseline-avg
              overrides -b, it plots baseline of computed average

       -d dump low VALUE
              ignore data less than VALUE

       -D dump high VALUE
              ignore data higher than VALUE

       -v verbose
              puts verbose runtime output to STDERR

       -L log makes y axis log scale

       -c colors "COLORS"
              set gnuplot colors for graph/axis/fonts/data  (default:  "xffffff  x000000  xc0c0c0
              x00a000 x0000a0 x2020c0" in order: bground, axis/fonts, grids, pointcolor1,2,3)

       -C cgi output CGI header to STDOUT if being called as CGI

       -s stats
              turn extra plot stats on (current, avg, min, max)

       -j julian times
              time columns is in local julian date (legacy stuff)

       -V version
              print version number and exit

       -h help
              display this help


         * TIME either unix date, julian date, or civil date in the form:
             YYYY:MM:DD:HH:MM (year, month, day, hour, minute)
           If you enter something with colons, it assumes it is civil date
           If you have a decimal point, it assumes it is julian date
           If it is an integer, it assumes it is unix date (epoch seconds)
           If it is a negative number, it is in decimal days from current time
             (i.e. -2.5 = two and a half days ago)
           * All times on command line are assumed to be "local" times
           * All times in the data file must be in unix date (epoch seconds)
         * RANGE is given in decimal days (i.e. 1.25 = 1 day, 6 hours)
         * if LINES == 0, (i.e. -l 0) then the whole data file is read in
         * columns (given with -x, -y, -Y flags) start at 1
         * titles given with -T can contain the following key words which will
           be converted:
             FILE - basename of input file
             RANGE - pretty civil date range (in local time zone)
           the default title is: FILE RANGE
