Hi all, is it possible to easily create Heat Maps in ArcGIS for JavaScript 4.5? In older versions like 3.x it was possible with the HeatMapRenderer I think. Kind Regards, Michael

OK, that means - we need a virtual/dedicated server to configure there PHP Apache/Java ApacheTomcat/DotNet IIS - app (javascript application files) has to be executed on the same server Kind Regards, Michael

Thank you Robert for your answer. We don't have acces to a dedicated/virtual server. We just have a ftp and a mysql database hosted on strato.de. Can we use the so called CORS on PHP (by adding " <?php header("Access-Control-Allow-Origin: *");" to the php script)? Or do we have to get a server for that? Best Regards, Leo

There is one Point feature in the layer. It was added to the layer by the push()-method. This one feature is displayed in map, so the layer can't be null (or what do you mean with "being ready"?).

Hi Thomas, your solution works great on the upper code snippet. I integrated your solution into my whole code and realized that it still doesn't work. I think it has something to do with the projection of my points with GeometryService and then pushing them into the layer. Can you say where the problem is? <script>

Hello together, I tried to zoom on a layer (containing 1 single point) in my MapView and got an error in the web console: #goTo() MapView cannot be used before it is ready See a code snippet below. Where's the problem? var zoomLayer = new FeatureLayer({...});
var view = new MapView({...});
view.then(goToLayer(zoomLayer));
function goToLayer(zoomLayer) {
view.goTo(zoomLayer.graphics);
} Thank you, Best Regards Michael

Hi all, I am working with JavaScript 4.4. With a FeatureLayer from URL clicking on overlapping graphics, the popUpTemplate shows all popUps (1 to 4... for example). Using a FeatureLayer with client side graphics ("source: features"), the popUpTemplate shows just the information about the feature lying on the top of them. Is it a bug? You can see my code below. Compare the two layers defined in my code by commenting and uncommenting please. Best Regards, Michael require([

Hi Thomas, what is happening now - when I execute my code (token from your sample), no objects are displayed in browser. When I refresh website, sometimes all objects are displayed, sometimes just a handful of objects. In your code you are using the then()-function. So what can be the problem? I think it's the GeometryService. It seems to be arbitrary hhow many objects are displayed. Is there no possibility to project whole FeatureLayers? Isn't loading each point into the project()-function very expensive? You can see my code below.

Hi all, I have a problem with touching my points in the map. The problem occurs in all sample codes from esri I tested (for example Reference Arcade expressions in PopupTemplate | ArcGIS API for JavaScript 4.4 ). I want to open a popUp of a point object but when touching it with my finger/with a pen, the map shifts a bit. It shifts just a little bit despite concentrating on doing a "steady" touch movement. Doing 4-5 concentrated touches, the popUp opens sometimes. Working outdoor makes it additionally difficult. This problem just occurs on the Samsung Tab Active!!! On all other tested smartphones/pc with mouse there is no problem. I already searched in android settings of the device to lower touch sensitivity but found nothing. Is there any possibility to lower the touch sensitivity of the map itself?

Thank you very much for the example code. That worked for me perfectly. To come back to the offline issue - Is there another possibility to transform/project features? The success of my application depends amongst others on the possibility to use it offline. Could I do that for example with python in background?

Tank you for your fast answers. @Thomas Solow, does this mean I have to outsource my javascript code from html/php file to .json and do there the projection? Could I do that also offline?

Hi, I want to reproject my FeatureLayer with client side Point features (wkid: 31468) into my streets basemap (default wkid: 4326). How can I do this. See me code below, there is one point in "features". There will be several thousand points in future to be displayed. var map = new Map({
basemap: "streets"
});
var view = new MapView({
center: [10.757158, 48.181567],
container: "viewDiv",
map: map,
zoom: 15
});
var features = [
{
geometry: new Point({
x: 4408681.069,
y: 5338984.143
})
}
];
var lyr = new FeatureLayer({
fields: [
{
name: "ObjectID",
alias: "ObjectID",
type: "oid"
}
],
objectIdField: "ObjectID",
geometryType: "point",
spatialReference: { wkid: 31468 },
source: features,
renderer: baumRenderer //custom renderer
});
map.add(lyr); Thank you very much for your help. Michael
