1.6.9 Data file format

The new datafile command can be used to specify information about the format of input data files, including the characters used to separate fields, to indicate comment lines, and to specify missing data. Gnuplot now attempts to recognize text fields with embedded blanks as single entities based on the datafile format settings. This allows input from csv (comma-separated value) files such as those exported by spreadsheet programs. See datafile. See also the `binary` option (introduced in 4.2).
