This example shows a googlemaps heatmap layer example for the heatmap.js gmaps plugin. Since it's a plugin make sure you don't forget to include gmaps-heatmap.js thank you, this example was useful

Demo

Code

// don't forget to add gmaps-heatmap.js
var myLatlng = new google.maps.LatLng(25.6586, -80.3568);
// map options,
var myOptions = {
  zoom: 3,
  center: myLatlng
};
// standard map
map = new google.maps.Map(document.getElementById("map-canvas"), myOptions);
// heatmap layer
heatmap = new HeatmapOverlay(map,
  {
    // radius should be small ONLY if scaleRadius is true (or small radius is intended)
    "radius": 2,
    "maxOpacity": 1,
    // scales the radius based on map zoom
    "scaleRadius": true,
    // if set to false the heatmap uses the global maximum for colorization
    // if activated: uses the data maximum within the current map boundaries
    //   (there will always be a red spot with useLocalExtremas true)
    "useLocalExtrema": true,
    // which field name in your data represents the latitude - default "lat"
    latField: 'lat',
    // which field name in your data represents the longitude - default "lng"
    lngField: 'lng',
    // which field name in your data represents the data value - default "value"
    valueField: 'count'
  }
);

var testData = {
  max: 8,
  data: [{lat: 24.6408, lng:46.7728, count: 3},{lat: 50.75, lng:-1.55, count: 1}, ...]
};

heatmap.setData(testData);
