Question

I am using the MarkerCluster.js to create clustering in my google maps api. The clusters work how I want them however I want to style differently than yellow, blue and red circles. I was trying to use the MarkerStyleOptions and it says you have an array of styles with the smallest cluster icon first and the biggest last. I tried to create this below but I am getting really confused about what syntax to use and can’t find any good examples.

var clusterStyles = [
    [opt_textColor: 'white'],
    [opt_textColor: 'white'],
    [opt_textColor: 'white']
];

var mcOptions = {
    gridSize: 50,
    styles: clusterStyles,
    maxZoom: 15
};
var markerclusterer = new MarkerClusterer(map, cluster, mcOptions);

What you need to do is use the url to specify which images to use instead of the blue/yellow/red images currently being used. And probably a good idea to include the height and width options too.

var clusterStyles = [
  {
    textColor: 'white',
    url: 'path/to/smallclusterimage.png',
    height: 50,
    width: 50
  },
 {
    textColor: 'white',
    url: 'path/to/mediumclusterimage.png',
    height: 50,
    width: 50
  },
 {
    textColor: 'white',
    url: 'path/to/largeclusterimage.png',
    height: 50,
    width: 50
  }
];
