Hi Bart,

there is a solution :-)
Not very elegant but the result is important...
Basically, you are creating a few dummy plots thereby extracting the 
columnheaders into string variables.
Then you create your desired plot using those variables.

Let me know whether it also works for you.

Theo.


I used the reduced data "Bart.dat":


"Dstat 0.7.2 CSV output"
"Author:","Dag Wieers <dag@wieers.com>",,
"Host:","maverick",,
"Cmdline:","dstat -tv --output dstat_timed.csv",,

"system","procs",,
"time","run","blk","new"

30-10 11:19:42,0.0,0.0,0.0,729186304.0

30-10 11:19:45,0.0,0.0,17.0,730214400.0



set datafile separator ","

# extract the columheaders from block 1 and point 1
# and store them in variables
# this will create some warnings which can be ignored
plot "Bart.dat" u (TitleCol2=stringcolumn(2),1):0 every ::1:1:1:1
plot "Bart.dat" u (TitleCol3=stringcolumn(3),1):0 every ::1:1:1:1
plot "Bart.dat" u (TitleCol4=stringcolumn(4),1):0 every ::1:1:1:1

set xlabel "Time"
set xdata time
set timefmt "%d-%m %H:%M:%S"
set format x "%H:%M"
set xrange [*:*]

plot "Bart.dat" u 1:2 every ::2:1 w lp t TitleCol2, \
              '' u 1:3 every ::2:1 w lp t TitleCol3, \
		 '' u 1:4 every ::2:1 w lp t TitleCol4
