First, you create a Gnuplot template (template.gp)

Code:

set datafile separator "|"
set xdata time
set timefmt '%H:%M:%S'
set terminal png
set output 'column-@COLUMN@.png'
set yrange [0:]
set title 'column @COLUMN@'
set grid
plot 'SCP_CAPS_24012012.txt' using 1:@COLUMN@ title 'column @COLUMN@' with linespoints

Now you can dynamically substitute @COLUMN@ with the actual column number and create all the graphs in a loop

Code:

for i in 2 3 4 5 6 7 8
do
    sed "s/@COLUMN@/$i/g" template.gp | gnuplot - > /dev/null 2>&1
done

BTW, you can also plot all the columns in one single PNG file

git-column

GIT-COLUMN(1)							    Git Manual							     GIT-COLUMN(1)

NAME

       git-column - Display data in columns

SYNOPSIS

       git column [--command=<name>] [--[raw-]mode=<mode>] [--width=<width>]
		    [--indent=<string>] [--nl=<string>] [--padding=<n>]

DESCRIPTION

       This command formats its input into multiple columns.

OPTIONS

       --command=<name>
	   Look up layout mode using configuration variable column.<name> and column.ui.

       --mode=<mode>
	   Specify layout mode. See configuration variable column.ui for option syntax.

       --raw-mode=<n>
	   Same as --mode but take mode encoded as a number. This is mainly used by other commands that have already parsed layout mode.

       --width=<width>
	   Specify the terminal width. By default git column will detect the terminal width, or fall back to 80 if it is unable to do so.

       --indent=<string>
	   String to be printed at the beginning of each line.

       --nl=<N>
	   String to be printed at the end of each line, including newline character.

       --padding=<N>
	   The number of spaces between columns. One space by default.
