Hi everyone ,
I want to change my point color based on the value from an array
the value named as (Temp) in the array .
Here is what I've did so far :

var graphicsLayer = new GraphicsLayer();
map.add(graphicsLayer);
for (i = 0; i < locs.length; i++) {
// create a point
var Point ={
type: "point",
longitude: locs[i].long,
latitude: locs[i].lat,

if(Point.Temp == 6){
var simpleMarkerSymbol = {

graphicsLayer.add(pointGraphic);
