可以通过以下代码示例解决这个问题：

var layer = new GraphicsLayer(); map.addLayer(layer);

// 创建一个点图形 var point1 = new Point(10, 10); var point2 = new Point(20, 20); var point3 = new Point(30, 30); var point4 = new Point(40, 40);

var pointSymbol = new SimpleMarkerSymbol( SimpleMarkerSymbol.STYLE_CIRCLE, 10, new SimpleLineSymbol( SimpleLineSymbol.STYLE_SOLID, new Color([171, 255, 30]), 1), new Color([255, 0, 0, 0.25]) );

var graphic1 = new Graphic(point1, pointSymbol); var graphic2 = new Graphic(point2, pointSymbol); var graphic3 = new Graphic(point3, pointSymbol); var graphic4 = new Graphic(point4, pointSymbol);

layer.add(graphic1); layer.add(graphic2); layer.add(graphic3); layer.add(graphic4);

// 创建featureCluster var fl = new FeatureLayer("http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Specialty/ESRI_StateCityHighway_USA/MapServer/0", { mode: FeatureLayer.MODE_ONDEMAND, outFields: ["*"], });

map.addLayer(fl);

var options = { featureLayer: fl, singleSymbol: pointSymbol, distance: 100, labelColor: "#fff", labelOffset: 10, resolution: map.extent.getWidth() / map.width, useDefaultSymbol: false, zoomOnClick: true, objectIdField: "OBJECTID", parentIdField: "ParentSen", clusterRatio: 75 };

var featureLayer = new FeatureLayer(fl.url, { id: "featureLayer" });

var clusterLayer = new ClusterLayer(options); clusterLayer.add(featureLayer); map.addLayer(clusterLayer);

现在，featureCluster应该可以与点图形一起正常工作。
