Cluster for graphic layer Arcgis Javascript 3.x

[ADITYAKUMAR1]

I have a graphic layer.

I want to cluster this data and display cluster on map(Arcgis JavaScript 3.x)

Any idea?

Hi Aditya,

Here are some samples for clustering in 3x:

Point clustering | ArcGIS API for JavaScript 3.29 

Toggle point clustering | ArcGIS API for JavaScript 3.29

Hi Ben,

clusterLayer = new ClusterLayer({
              "data": photoInfo.data,
              "distance": 100,
              "id": "clusters",
              "labelColor": "#fff",
              "labelOffset": 10,
              "resolution": map.extent.getWidth() / map.width,
              "singleColor": "#888",
              "singleTemplate": popupTemplate
            });

In my case what will be the data?

Thanks

Kumar

This is how I would turn on clustering

var layer = new FeatureLayer(serviceUrl, {
      featureReduction: {
        type: "cluster"
      }
})‍‍‍‍‍

Here is a simple sample to demonstrate the code above

Hi ADITYA KUMAR‌, the data will be

photoInfo.data = arrayUtils.map(resp, function(p) {
              var latlng = new  Point(parseFloat(p.lng), parseFloat(p.lat), wgs);
              var webMercator = webMercatorUtils.geographicToWebMercator(latlng);
              var attributes = {
                "Caption": p.caption,
                "Name": p.full_name,
                "Image": p.image,
                "Link": p.link
              };
              return {
                "x": webMercator.x,
                "y": webMercator.y,
                "attributes": attributes
              };

so basically an array with the following structure.

           {
                "x": 120,
                "y": -32,
                "attributes": {

                     "Caption": "caption",
                     "Name": "a name",
                     "Image": small.jpg,
                    "Link": "http link"

                    }
              };

Hi Adithya, Can you pls tell me which module have you imported for ClusterLayer? Currently i'm using 4.20 JS API version.

Is it possible to add clustering to graphics layer in version 4.27 ?
featureReduction props is not available in the docs also.

https://developers.arcgis.com/javascript/latest/api-reference/esri-layers-GraphicsLayer.html#propert...

Is it possible to have clustering if it has only points geometry in graphics layer ? i know Polygon and Line string is not supported
