Re: [Gnuplot-info] gnuplot graph setup help

[Thomas S. <t.s...@fz...>]

set xdata time
set timefmt "%Y%m%d %H:%M:%S"
plot  "/tmp/disk.dat-web01-20090523.dsk" using 1:4 title '[DSK:sda]Reads', \
"" using 1:5 title '[DSK:sda]RMerge', \
"" using 1:6 title '[DSK:sda]RKBytes', \
...

it makes no sense to plot 'Date' and 'Time', these values are on the x-axis.
and, plotting a string ('Name') makes no sense, too.

more information you can find in the manual:
http://www.gnuplot.info/docs/gnuplot.html
or use the 'help' command within gnuplot:
help timefmt
help set xdata
help ...
