ArcGIS API is illustrating a Heat Map sample at This Sandbox
var serviceURL = "//services.arcgis.com/V6ZHFr6zdgNZuVG0/arcgis/rest/services/2012_CA_NHTSA/FeatureServer/0";var heatmapFeatureLayerOptions = { mode: FeatureLayer.MODE_SNAPSHOT, infoTemplate: infoTemplate, outFields: [ "atmcond", "numfatal", "conszone", "age", "alcres", "sex" ]};var heatmapFeatureLayer = new FeatureLayer(serviceURL, heatmapFeatureLayerOptions);var heatmapRenderer = new HeatmapRenderer();heatmapFeatureLayer.setRenderer(heatmapRenderer);map.addLayer(heatmapFeatureLayer);Can you please let me know how I can do this based on an array of points like
var points = [ { "ProjectID":"15260", "Longitude":"-118.641508", "Latitude":"51.949915", }, { "ProjectID":"17043", "Longitude":"-125.444557", "Latitude":"51.097552", }, .... { "ProjectID":"13009", "Longitude":"-130.257086", "Latitude":"56.882834", }, { "ProjectID":"17088", "Longitude":"-124.160699", "Latitude":"50.897618", }];instead of a Map service?
Thanks
