Access Attribute of individual feature in the feature layer create using client side graphics.

I have been trying to color individual colors graphics which are added using client-side graphics in the feature layer. but the symbol property of the graphic is overwritten by the renderer property of the feature layer.
I have taken the source as the array of graphics with a symbol property of simpleMarkerSymbol . simpleMarkerSymbol Provides different colors to the symbol based on the values it gets from the backend. So I want to color individual graphics once the cluster_number is equals to 1.

this.mapNodes.forEach((node,i)=>{ // this.mapNodes is the data from API

this.simpleMarkerSymbol = {

type: "simple-marker",

color: node.colorCode,

style: "circle",

size: "10px",

outline: {

color: node.colorCode,

width: 3

}

};

let point = new Point({ x: node.longitude, y: node.lattitude });

let graphic = new Graphic({

geometry: point,

symbol: this.simpleMarkerSymbol,

attributes: {

name: node.nodeName,

color:node.colorCode

});

this.graphics.push(graphic);

});

var action:any = {

id: MapViewConstant.FIND_FEATURES,

title: "Open-Chart",

};

this.nodeLayer=new FeatureLayer({

featureReduction:MapViewConstant.clusterConfig,

source:this.graphics,

fields:MapViewConstant.fields,

objectIdField:MapViewConstant.OBJECT_ID,

popupTemplate: {

title: "{name}",

actions:[action]

renderer:MapViewConstant.renderer // it provides grey color to all the features

});

this.Map.add(this.nodeLayer);

Features in a FeatureLayer can only be symbolized by the renderer of the FeatureLayer.

We have a guide on visualization that might help.

From your description, it sounds like you might want to use a Unique Value Renderer.
