Discrete data contained in a file can displayed by specifying the
name of the data file (enclosed in quotes) on the 'plot' command
line.
Data files should contain one data point per line. A data point may
be specified either as an X and Y value separated by blank space, or
as just the Y value, in which case the program will use the number
of the coordinate as the X value. Coordinate numbers starts at 0
and are incremented for each data point read. Blank lines and lines
beginning with # will be treated as comments and ignored.
This example compares the data in the file population.dat to a
theoretical curve:
pop(x) = 103*exp((1965-x)/10)
plot [1960:1990] 'population.dat', pop(x)
The file population.dat might contain:
# Gnu population in Antarctica since 1965
1965 103
1970 55
1975 34
1980 24
1985 10
