Most probably your data is simply to short in relation to the fft
length and the amount of samples your specific graphical FFT amplitude
sink drops for display.
Please review you fft length, update rate, and try out different fft
GUIs (qt/wx).

You could zeropad your data generously to notice the repitition.
However, I think with what you're describing you might be better off
with a waterfall graph; try them, they're fun :)

Greetings,
Marcus
