Hello, I am working on react and I want to show the Line feature at a given scale with definitionExpression. For example, if the scale is less than 20000 then show only network 1 while scale is greater than 20000 then show all records on map. The following statement is not working well. Is anyone can help me? if (_this.state.scale < 20000){
geojsonServiceFiber.definitionExpression = "network = 1"
}
if (_this.state.scale > 20000){
geojsonServiceFiber.definitionExpression = "1=1"
}

Hi I am going to show centroid points of the polygon as a textSymbol on the map but an issue that I am facing, the total features of the polygon are 69048 but 14570 centroid points are displaying on the map. For better understanding, I have created the point symbol of centroids, as you can see in the attached image the centroid points of some polygons are not showing. Anyone can help me? Robert Scheitlin, GISPEgge-Jan Pollé let parcelSDE = new FeatureLayer({
url: "Service URL",
title: "Parcel",
labelsVisible: true,
legendEnabled: true,
})
map.add(parcelSDE)
var parcel = parcelSDE.createQuery();
parcel.where = "1=1"
parcelSDE.queryFeatures(parcel).then(function (response) {
response.features.map((e, i) => {
console.log(i)
//69048 features
var points = {
type: "point",
x: e.geometry.centroid.x,
y: e.geometry.centroid.y,
spatialReference: { wkid: 32642 }
};
var textSymbol = {
type: "text",
color: "black",
haloColor: "white",
text: e.attributes.house_no,
haloSize: 1,
font: {
family: "Arial",
size: 6,
weight: "bold"
}
};
/* let symbol = {
type: "simple-marker",
size: 5,
color: [0, 255, 255],
outline: null
} */
var pointGraphic = new Graphic({
geometry: points,
symbol: textSymbol
});
console.log(pointGraphic)
// 14570 centroid points
view.graphics.add(pointGraphic)
})
})

Wao its wonderful Egge-Jan thank you so much and yes i have tested labeling with 4.12 version its working properly. Basically i find such type of stuff that you had shared in which we can use button to LayerList widget for labeling. Again thank you Egge-Jan

Hi Any one can please guide me or give me a sample to understand how can create Polyline feature layer with web service(JSON). I have created Point feature layer with web service but i am stuck to create line feature that how can i loop path/segments.

Hi I am confused to calculate total length of line feature with arcgis API for java script. any one can help me...??? I found following code but it's not working. let geometryService = new GeometryService({
url:url
})
geometryService.simplify([line]).then(function (line) {
var areasAndLengthParams = new LengthsParameters({
lengthUnit: "kilometers",
polylines: line
});
console.log(areasAndLengthParams)
/* geometryService.Length(areasAndLengthParams).then(function (results) {
console.log("area: ", results.areas[0]);
console.log("length: ", results.lengths[0]);
}); */
});
