Wendi, It is hard to guess now a days which version people are using. Here is a sample for 3.18 then: <!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <meta name="viewport" content="initial-scale=1, maximum-scale=1,user-scalable=no"> <title>Map with legend</title> <link rel="stylesheet" href="https://js.arcgis.com/3.18/dijit/themes/claro/claro.css"> <link rel="stylesheet" href="https://js.arcgis.com/3.18/esri/css/esri.css"> <style> html, body { height: 97%; width: 98%; margin: 1%; } #rightPane { width: 20%; } #legendPane { border: solid #97DCF2 1px; } </style> <script src="https://js.arcgis.com/3.18/"></script> <script> var map; require([ "esri/map", "esri/layers/ArcGISDynamicMapServiceLayer", "esri/dijit/Legend", "dojo/_base/array", "dojo/parser", "dijit/layout/BorderContainer", "dijit/layout/ContentPane", "dijit/layout/AccordionContainer", "dojo/domReady!" ], function( Map, ArcGISDynamicMapServiceLayer, Legend, arrayUtils, parser ) { parser.parse(); map = new Map("map", { basemap:"topo", center: [-96.53, 38.374], zoom: 4 }); var radar = new ArcGISDynamicMapServiceLayer("https://nowcoast.noaa.gov/arcgis/rest/services/nowcoast/radar_meteo_imagery_nexrad_time/MapServer"); //add the legend map.on("layers-add-result", function (evt) { var layerInfo = arrayUtils.map(evt.layers, function (layer, index) { return {layer:layer.layer, title:layer.layer.name}; }); if (layerInfo.length > 0) { var legendDijit = new Legend({ map: map, layerInfos: layerInfo }, "legendDiv"); legendDijit.startup(); } }); map.addLayers([radar]); }); </script> </head> <body class="claro"> <div id="content" data-dojo-type="dijit/layout/BorderContainer" data-dojo-props="design:'headline', gutters:true" style="width: 100%; height: 100%; margin: 0;"> <div id="rightPane" data-dojo-type="dijit/layout/ContentPane" data-dojo-props="region:'right'"> <div data-dojo-type="dijit/layout/AccordionContainer"> <div data-dojo-type="dijit/layout/ContentPane" id="legendPane" data-dojo-props="title:'Legend', selected:true"> <div id="legendDiv"></div> </div> <div data-dojo-type="dijit/layout/ContentPane" data-dojo-props="title:'Pane 2'"> This pane could contain tools or additional content </div> </div> </div> <div id="map" data-dojo-type="dijit/layout/ContentPane" data-dojo-props="region:'center'" style="overflow:hidden;"> </div> </div> </body> </html> ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Thank you Robert!  I am using 3.9 but will look into updating to 4.1.  Also, I was using "DynamicMapServiceLayer" which probably isn't necessary.
