I am trying to read some files whit different columns whose first row
contain the "name" of the key (title). From other posts and
documentation I found that using:
set key autotitle columnhead[er]
should do the trick however when I use it i got the following error:
"undefined variable: columnheader"
It is worth nothing I am using "gnuplot version 4.0. patchlevel 0" .
Is this feature not available in the version I am using? or what am I
doing wrong? is there any other way to do it (I am using my University
machine for which I have no root access hence I can not patch/update
