check if point exist in geometry query feature layer

[SriharshaK]

Hello guys! I am trying to plot polygon layers on existing feature layer. Before that I need to get if points exist in a particular geometry after querying the feature layer. Can I also show different color for rings of polygon?

Here is my code below.

            const queryNew = myFeatureLayer.createQuery();
            queryNew.spatialRelationship = "intersects";
            queryNew.returnGeometry = true;
            myFeatureLayer.queryFeatures(queryNew).then(function (results) {
              const result = results.features.map((data) => data.geometry["rings"][0]);
              
              const poly = new Polygon({
                spatialReference: {
                  wkid: 4283
                },
              });

              slider.on("thumb-drag", function (event) {

                const filterForecast = forecast.filter(
                  (data) =>
                    data.poaching_risk * 100 > slider.values[0] &&
                    data.poaching_risk * 100 < slider.values[1]
                );

                var riskLatlonFilter = (filterForecast as unknown as any[]).map(
                  (element) => {
                    return [element.lon, element.lat];
                  }
                );

                console.log(riskLatlonFilter);
              });
            });

It doesn't look like you've set the geometry property of your "queryNew" query object. Set that to be the geometry of the polygon(s) you want to intersect the features in "myFeatureLayer".

Can I change colour for different polygon.

That's a vague question, but generally, Yes. Check out Data-driven styles. Here's a tutorial.

If you want to style based on something else, you could look into making a Graphics Layer and applying the symbology however you want.
