More diverse cluster sizes about js-marker-clusterer HOT 2 OPEN

Probably in the "calculator" function. There is where that "index" is calculated.

MarkerClusterer.prototype.calculator_ = function(markers, numStyles) {
...

In the original it change at steps "x10". Maybe you could alter your override depending on the zoom level or some other available data before the cluster is computed/rendered.

@dylanfitz fwiw, here's what I did to adjust the steps.

• Save https://googlemaps.github.io/js-marker-clusterer/src/markerclusterer.js to a local file.

• Replace this:

  MarkerClusterer.prototype.calculator_ = function(markers, numStyles) {
    var index = 0;
    var count = markers.length;
    var dv = count;
    while (dv !== 0) {
      dv = parseInt(dv / 10, 10);
      index++;
    }

• With this:

  MarkerClusterer.prototype.calculator_ = function(markers, numStyles) {
    var index = 1;
    var count = markers.length;
    var dv = count;
    dv = parseInt(dv);
    if(dv >= 20) {
      index = 5;
    } else if(dv >= 10) {
      index = 4;
    } else if(dv >= 5) {
      index = 3;
    } else if(dv >= 3) {
      index = 2;
    }

Now I get clusters at steps of 2 (default minimum cluster size), 3, 5, 10, and 20. It's not math-y like the base-10 scale, and is not generalized, but it's good enough for a very specific use case.
