Full resolution(1,300 × 975 pixels, file size: 2 KB, MIME type: image/png)

This graph was created by me using the following bit of gnuplot

set terminal png size 1300, 975

# set xlabel "Days ago (0 today, 1 yesterday, etc)" 0, -2
#
# something evil happens with "xtics axis", need dummy xlabel
set xlabel " " 0, -2
set xrange [-0.5:20.5]
set xtics axis 5
set mxtics 5

# set ylabel "Weight (frac)"
#
set yrange [0:0.15]
set format y "%.2f"

unset key
set style fill solid 1.0
set boxwidth 0.6 relative
plot "ema.data" with boxes

and ema.data file generated by the following bit of perl

$N = 15;
$f = 1 - 2/($N+1);

$total = 0;
foreach $i (0..20) {
  $value = (1 - $f) * ($f ** $i);
  print "$i $value\n";
  $total += $value;
}
print "# total $total (should approach 1)\n";
