display xy without creating a feature layer

hi, is it possible to display a xy without creating a feature layer? From an api call I get the xy information, and I want to show where they are located on the map in AGP. But I don’t what to create a feature layer, because the user are going to use the function multiply times, and I don’t want the TOC to be flooded with feature layers.

You can look at this community sample:

arcgis-pro-sdk-community-samples/Map-Authoring/GraphicsLayers at 24c3224cc4566ab69c77b0bff40bff025628a341 · Esri/arcgis-pro-sdk-community-samples · GitHub

It contains code to create a graphics layer (see AddGraphicsLayer.cs) and the code to add a point to that graphic layer (see GraphicCreationTools/PointGraphic.cs).

The ProConcepts document for graphics layers is here: ProConcepts GraphicsLayers · Esri/arcgis-pro-sdk Wiki (github.com)

You can also use an extension method on the MapView class: AddOverlay to add a Symbol (point, line, polygon) to a MapView's grphic overlay. AddOverlay Method (MappingExtensions)—ArcGIS Pro

Here is the documentation on Graphic Overlays for MapView:

ProConcepts Map Exploration · Esri/arcgis-pro-sdk Wiki (github.com)

private IDisposable _graphic = null; //defined elsewhere // Add point graphic to the overlay at the center of the mapView // Note: Run within QueuedTask.Run _graphic = mapView.AddOverlay(mapView.Extent.Center, SymbolFactory.Instance.ConstructPointSymbol( ColorFactory.Instance.RedRGB, 40.0, SimpleMarkerStyle.Star).MakeSymbolReference()); // Note: Update graphic using UpdateOverlay // mapView.UpdateOverlay(_graphic,...); _graphic.Dispose(); //Removes the graphic
