example datafile

This example plots the data in the file "population.dat" and 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
