How do I change marker cluster options?
The MarkerClusterer library allows you to change several options for marker clustering. Here are the steps to change cluster options:
- Include the necessary libraries in your HTML file:
- Create a map object and an array of markers:
- Initialize the marker clusterer with the desired options:
- Customize the cluster icon using CSS:
<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&libraries=places&callback=initMap" async defer></script> <script src="https://developers.google.com/maps/documentation/javascript/examples/markerclusterer/markerclusterer.js"></script>
var map; var markers = []; function initMap() { map = new google.maps.Map(document.getElementById('map'), { zoom: 3, center: { lat: -28.024, lng: 140.887 } }); // Add markers to the markers array var markerCluster = new MarkerClusterer(map, markers, { /* options here */ }); }
var markerCluster = new MarkerClusterer(map, markers, { gridSize: 60, maxZoom: 8, styles: [{ /* cluster styles */ }], /* other options */ });
.cluster-icon { background-image: url('path/to/your/icon.png'); /* other styles */ }
How do I customize the cluster icon using Google Maps API with MarkerClusterer?
To customize the cluster icon, you can use the `styles` option in the marker clusterer configuration. The `styles` option allows you to specify an array of custom styles for different cluster sizes.
Here’s an example of customizing the cluster icon using Google Maps API with MarkerClusterer:
var markerCluster = new MarkerClusterer(map, markers, { styles: [ { url: 'path/to/your/icon.png', height: 40, width: 40, textColor: 'white', textSize: 12 }, // Add more styles for different cluster sizes ] });
In the above example, the cluster icon is customized by providing a URL to the desired icon image. You can also specify the height, width, text color, and text size for the cluster icon.
Make sure to replace `’path/to/your/icon.png’` with the actual path to your desired cluster icon image.
