In bullet.js, there is a bulletRanges() function, where you can change the ranges manually. In the example, it is changed in the randomize() function:

function randomize(d) {
  if (!d.randomizer) d.randomizer = randomizer(d);
  d.ranges =;  //This changes the ranges in the SVG datum.
  d.markers =;
  d.measures =;
  return d;

To update the chart with the data, is then invoked.
