pro weird_fft_2
tek_color
out_old=0
for k=0, 10 do begin
if k eq 0 then plot_io ,abs(fft(findgen(2.^10.),-1)), $
xrange=[100,2.^10. ], $
color=1, /nodata
ggg=strcompress(string(2^k))
xyouts, 0.2, 0.2, out_old, /norm, charsize=1.5, color=0
xyouts, 0.2, 0.2, ggg, /norm, charsize=1.5, color=k+1
oplot,abs(fft(findgen(2^k),-1)), color=k+1
out_old=ggg
endfor
return
end

Looks like good old "don't use number of samples other than power of 2 with
