UniqueValueRenderer

Hi all

Using jsapi 4

Am now trying to symbolise some species polygons based on a field where a species distribution range is resident, breeding, non-breeding etc. I am passing a query into a graphic layer and can symbolise ranges using the following:

function getQueryResults(response) {

var parcelResults = arrayUtils.map(response.features, function(feature) {

feature.symbol = new SimpleFillSymbol({

color: [255, 255, 0, 0.25],

style: "solid",

outline: {

color: [255, 255, 0],

width: 3

}

});

return feature;

});

return parcelResults;

}

Obviously, this returns each species distribution part in yellow when what I want to do is use UniqueValueRenderer but cannot seem to get this to work here, any help/advice much appreciated.

Hi Mark, have you looked at the example on this page: UniqueValueRenderer | API Reference | ArcGIS API for JavaScript 4.0

You need to define the renderer first, then apply it to the FeatureLayer.
