What do you mean the numeric part incrementing by one, each execution?

Here is a short example:
x:makelist(k,k,1,1024)$ /* Ramp from 1 to 1024 */
y:fft(x)$
plot2d([discrete, x, abs(y)^2], [logy]);
This should produce a semilog plot of the frequency spectrum
(magnitude) of x.
If this doesn't work for you, let us know.
