topic Display UniqueValueRenderer symbols in custom legend? in ArcGIS JavaScript Maps SDK Questions https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/display-uniquevaluerenderer-symbols-in-custom/m-p/749297#M69320 <HTML><HEAD></HEAD><BODY><P><SPAN style="font-size: 10pt; font-family: arial, helvetica, sans-serif;">I recently figured out how to use esri/request to retrieve legend images from our server to make a custom legend div. However, now I am moving onto using the UniqueValueRenderer for layers after they load....so all the symbols are changing. In the JavaScript API documentation it mentions that .<A href="https://developers.arcgis.com/javascript/jsapi/uniquevaluerenderer-amd.html">getUniqueValueInfo</A>(graphic) "<SPAN style="color: #4d4d4d;">Returns rendering and legend information (as defined by the renderer) associated with the given graphic." I'm not sure what graphic to feed it though. It doesn't work if I offer it the layer with the renderer assigned to it or its graphics or a single graphic (e.g. renderer.getUniqueValueInfo(layer.graphics[0])).</SPAN></SPAN></P><P></P><P><SPAN style="font-size: 10pt; font-family: arial, helvetica, sans-serif;">Does anyone have tips on getting images from a layer with a renderer to use in the legend?</SPAN></P><P></P><P><SPAN style="font-size: 10pt; font-family: arial, helvetica, sans-serif;">Thanks for any help.</SPAN></P></BODY></HTML> Thu, 10 Jul 2014 19:34:35 GMT Anonymous User 2014-07-10T19:34:35Z Display UniqueValueRenderer symbols in custom legend? https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/display-uniquevaluerenderer-symbols-in-custom/m-p/749297#M69320 <HTML><HEAD></HEAD><BODY><P><SPAN style="font-size: 10pt; font-family: arial, helvetica, sans-serif;">I recently figured out how to use esri/request to retrieve legend images from our server to make a custom legend div.
