Not Able to Render Simple Marker Renderer on Feature Layer

Question

Can you please take a look at this demo and let me know why I am not able to add the simple render / Simple Marker to the map for feature layers require([ "esri/map", "esri/layers/FeatureLayer", "esri/renderers/SimpleRenderer", "esri/symbols/SimpleMarkerSymbol", "esri/symbols/SimpleLineSymbol", "esri/Color", "dojo/domReady!" ], function( Map, FeatureLayer, SimpleRenderer, SimpleMarkerSymbol, SimpleLineSymbol, Color, ) { var map = new Map("map", { basemap: "streets", center: [-82.44109, 35.6122], zoom: 17 }); var featureLayer = new FeatureLayer("https://services.arcgis.com/V6ZHFr6zdgNZuVG0/arcgis/rest/services/Landscape_Trees/FeatureServer/0"); featureLayer.setRenderer( new SimpleMarkerSymbol(SimpleMarkerSymbol.STYLE_SQUARE, 10, new Color([0,255,0,0.25]))); map.addLayer(featureLayer); });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Bruce, * You are trying to set the FeatureLayers renderer to a SimpleMarkerSymbol and not a actual renderer. * You left out the outline portion of the SimpleMarkerSymbol constructor. If you do not want to specify it then you have to pass null at least. require([ "esri/map", "esri/layers/FeatureLayer", "esri/renderers/SimpleRenderer", "esri/symbols/SimpleMarkerSymbol", "esri/symbols/SimpleLineSymbol", "esri/Color", "dojo/domReady!" ], function( Map, FeatureLayer, SimpleRenderer, SimpleMarkerSymbol, SimpleLineSymbol, Color, ) { var map = new Map("map", { basemap: "streets", center: [-82.44109, 35.6122], zoom: 17 }); var featureLayer = new FeatureLayer("https://services.arcgis.com/V6ZHFr6zdgNZuVG0/arcgis/rest/services/Landscape_Trees/FeatureServer/0"); featureLayer.setRenderer(new SimpleRenderer(new SimpleMarkerSymbol(SimpleMarkerSymbol.STYLE_SQUARE, 10, new SimpleLineSymbol(), new Color([0, 255, 0, 0.25])))); map.addLayer(featureLayer); });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
