The set datafile commentschars tells gnuplot what characters are used in a
data file to begin comment lines. If the first non-blank character on a line is
one of the specified characters then the rest of the input line is ignored.
Default value of the string is "#!" on VMS and "#" otherwise.
Syntax:
set datafile commentschars {"<string>"}
show datafile commentschars
unset commentschars
Then, the following line in a data file is completely ignored
# 1 2 3 4
but the following
1 # 3 4
produces a rather unexpected plot unless
set datafile missing '#'
is specified as well.
Example:
set datafile commentschars "#!%"
