STRIPCHART(5) File Formats Manual STRIPCHART(5) NAME
stripchart - draws diagrams from data with PHP SYNOPSIS
The script is expected to be called as a CGI script but also works from the command line. DESCRIPTION
Stripchart prepares a series of diagrams directly from raw data. It is handy for web pages that need some graphics without too much over- head. OPTIONS
-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/axisnts/data (default: "xffffff x000000 xc0c0c0 x00a000 x0000a0 x2020c0" in order: bground, axisnts, 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 NOTES
* 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 AUTHORS
