Reading one 'a' from a file, then making a plot if it, is trivial: just
make the file read
a = 1
then
load 'file'
plot f(x)
For more complex cases, e.g. involving a single plot, multiple different
values of 'a', but only one defined function f, this won't work  it
would require the 'plot' command to run two nested loops, one over the
table of values for 'a', the other over 'x'. gnuplot doesn't do that.
