Gnuplot makes tics at 1e4, 2e4 3e4, not on 10*2^10, 20*2^10, etc.

You'll have to set the xtics yourself.

	stats ....
	log2(x) = log(x)/log(2)
	ymax = 2**ceil(log2(stats_max_y))

	set ytics ymax/8

or something similar.

And you cannot get lost of the "i" for binary magitudes. You can use the
format string "%s %c" for kilogramms or computer salespeople's
gigabytes. Which are not gigabytes. ;-)

check "help format specifier"
