3.24.16.5 set datafile commentschars

The `set datafile commentschars` command allows you to tell `gnuplot` what characters are used in a data file to denote comments. Gnuplot will ignore rest of the line behind the specified characters if either of them is the first non-blank character on the line.

Syntax:

           set datafile commentschars {"<string>"}
           show datafile commentschars
           unset commentschars
     

Default value of the string is "#!" on VMS and "#" otherwise.

Then, the following line in a data file is completely ignored

         # 1 2 3 4

but the following

         1 # 3 4

produces rather unexpected plot unless

         set datafile missing '#'

is specified as well.

Example:

           set datafile commentschars "#!%"
