I found a method that satisfies my requirement for elegance, so for the 
benefit of the archives:

    #
    # Gnuplot doesn't have max()?
    #
    max(x, y) = (x > y) ? x : y

    [...]

    plot datafile using 1:(max($7, 0.1)) lt rgb "dark-pink" title 'Spam'

I should make "0.1" a variable such as "epsilon" or something.
