Class: @arcgis/core/Graphic
Since: ArcGIS Maps SDK for JavaScript 4.0
A Graphic is a vector representation of real world geographic phenomena. It can contain geometry, a symbol, and attributes. A Graphic is displayed in the GraphicsLayer.
To learn how to work with graphics, see the Intro to graphics tutorial.

Property DetailsSince: ArcGIS Maps SDK for JavaScript 4.23 Graphic since 4.29, aggregateGeometries added at 4.23.
The aggregateGeometries contains spatial aggregation geometries when statistics query is executed with envelope-aggregate
, centroid-aggregate
and/or convex-hull-aggregate
statistics type. Each property on aggregateGeometries is populated with statistics field containing the aggregate geometry matching the aggregate statistics type.
Example
// average of age fields by regions
const ageStatsByRegion = new StatisticDefinition({
onStatisticField: field,
outStatisticFieldName: "avgAge",
statisticType: "avg"
});
// extent encompassing all features by region
const aggregatedExtent = new StatisticDefinition({
statisticType: "envelope-aggregate",
outStatisticFieldName: "aggregateExtent",
});
// group the statistics by Region field
// get avg age by Regions and extent of each region
const query = layer.createQuery();
query.groupByFieldsForStatistics = ["Region"];
query.outStatistics = [consumeStatsByRegion, aggregatedExtent];
layer.queryFeatures(query).then((results) => {
results.features.forEach((feature) => {
if (feature.attributes.Region === "Midwest") {
view.goTo(feature.aggregateGeometries.aggregateExtent);
}
});
});
attributes Object
Name-value pairs of fields and field values associated with the graphic.
Example
let graphic = new Graphic();
graphic.attributes = {
"name": "Spruce",
"family": "Pinaceae",
"count": 126
};
Inherited
Property declaredClass Stringreadonly
Since: ArcGIS Maps SDK for JavaScript 4.7 Accessor since 4.0, declaredClass added at 4.7.
The name of the class. The declared class name is formatted as esri.folder.className
.
The geometry that defines the graphic's location.
Z-values defined in a geographic or metric coordinate system are expressed in meters. However, in local scenes that use a projected coordinate system, vertical units are assumed to be the same as the horizontal units specified by the service.
Example
// First create a point geometry
let point = {
type: "point", // autocasts as new Point()
longitude: -71.2643,
latitude: 42.0909
};
// Create a symbol for drawing the point
let markerSymbol = {
type: "simple-marker", // autocasts as new SimpleMarkerSymbol()
color: [226, 119, 40]
};
// Create a graphic and add the geometry and symbol to it
let pointGraphic = new Graphic({
geometry: point,
symbol: markerSymbol
});
isAggregate Booleanreadonly
Since: ArcGIS Maps SDK for JavaScript 4.18 Graphic since 4.29, isAggregate added at 4.18.
Indicates whether the graphic refers to an aggregate, or cluster graphic. Aggregate graphics represent clusters of features. If a graphic is an aggregate, you can use its Object ID to query the features comprising the cluster.
If applicable, references the layer in which the graphic is stored.
Since: ArcGIS Maps SDK for JavaScript 4.29 Graphic since 4.29, origin added at 4.29.
Returns information about the origin of a graphic if applicable. Origin information about a graphic can be returned as a result of the hitTest()
or queryFeatures()
method. It can include information such as a layer in which the graphic originates from. Information returned in the origin depends on the origin type.
Example
// get screen point from view's click event
view.on("click", (event) => {
// Search for all features only on included layers at the clicked location
view.hitTest(event, {include: vectorTileLayer}).then((response) => {
// if graphics are returned from vector tile layer, do something with results
if (response.results.length){
response.results.forEach((result, i) => {
const layerId = result.graphic?.origin?.layerId;
const styleLayer = vectorTileLayer.getStyleLayer(layerId);
// update layer's style
});
}
})
});
The template for displaying content in a Popup when the graphic is selected. The PopupTemplate may be used to access a graphic's attributes and display their values in the view's default popup. See the documentation for PopupTemplate for details on how to display attribute values in the popup.
As of 4.8, to get the actual popupTemplate
of the graphic, see the getEffectivePopupTemplate() method that either returns this value or the popupTemplate
of the graphic's layer.
Example
// The following snippet shows how to set a popupTemplate
// on the returned results (features) from identify
idResult.feature.popupTemplate = {
title: "{NAME}",
content: [{
// Pass in the fields to display
type: "fields",
fieldInfos: [{
fieldName: "NAME",
label: "Name"
}, {
fieldName: "REGION",
label: "Region"
}]
}]
};
The Symbol for the graphic. Choosing a symbol for a graphic depends on the View type (SceneView or MapView), and the geometry type of the graphic.
Each graphic may have its own symbol specified when the parent layer is a GraphicsLayer. For a FeatureLayer the symbol of each graphic should not be set by the developer since the graphics' rendering properties are determined by the layer's renderer.
To change a graphic's symbol in the GraphicsLayer and in the view.graphics at runtime, one of the following can be done:
Example
view.on("click", function(event){
let graphic = new Graphic({
geometry: event.mapPoint,
symbol: {
type: "simple-marker", // autocasts as new SimpleMarkerSymbol()
color: "blue",
size: 8,
outline: { // autocasts as new SimpleLineSymbol()
width: 0.5,
color: "darkblue"
}
}
});
});
Indicates the visibility of the graphic.

Method DetailsInherited
Method addHandles(handleOrHandles, groupKey)
Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, addHandles added at 4.25.
Adds one or more handles which are to be tied to the lifecycle of the object. The handles will be removed when the object is destroyed.
// Manually manage handles
const handle = reactiveUtils.when(
() => !view.updating,
() => {
wkidSelect.disabled = false;
},
{ once: true }
);
this.addHandles(handle);
// Destroy the object
this.destroy();
Parameters
Handles marked for removal once the object is destroyed.
groupKey *
optionalKey identifying the group to which the handles should be added. All the handles in the group can later be removed with Accessor.removeHandles(). If no key is provided the handles are added to a default group.
clone(){this}
Creates a deep clone of this object. Any properties that store values by reference will be assigned copies of the referenced values on the cloned instance.
Returns
Type Description this A deep clone of the class instance that invoked this method.Creates a new instance of this class and initializes it with values from a JSON object generated from an ArcGIS product. The object passed into the input json
parameter often comes from a response to a query operation in the REST API or a toJSON() method from another ArcGIS product. See the Using fromJSON() topic in the Guide for details and examples of when and how to use this function.

Returns the popup template applicable for the graphic. It's either the value of popupTemplate or the popupTemplate
from the graphic's layer.
Parameter
defaultPopupTemplateEnabled Boolean optionalDefault Value: false
Whether support for default popup templates is enabled. When true, a default popup template may be created automatically if neither the graphic nor its layer have a popup template defined.
Returns
