Class: esri/Graphic
Inheritance: Graphic Accessor
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.

let polyline = {
  type: "polyline",  // autocasts as new Polyline()
    paths: [
      [-111.30, 52.68],
      [-98, 49.5],
      [-93.94, 29.89]
    ]
};

let polylineSymbol = {
  type: "simple-line",  // autocasts as SimpleLineSymbol()
  color: [226, 119, 40],
  width: 4
};

let polylineAtt = {
  Name: "Keystone Pipeline",
  Owner: "TransCanada"
};

let polylineGraphic = new Graphic({
  geometry: polyline,
  symbol: polylineSymbol,
  attributes: polylineAtt
});

view.graphics.add(polylineGraphic);

Property Details

aggregateGeometries Object
Since: ArcGIS Maps SDK for JavaScript 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.

See also
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
};
declaredClass Stringreadonly inherited
Since: ArcGIS Maps SDK for JavaScript 4.7

The name of the class. The declared class name is formatted as esri.folder.className.

geometry Geometryautocast

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

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.

See also
layer Layer

If applicable, references the layer in which the graphic is stored.

popupTemplate PopupTemplateautocast

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.

See also
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:

  1. Clone the symbol and change its properties.
  2. Assign a new symbol to the graphic.
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"
      }
    }
  });
});
visible Boolean

Indicates the visibility of the graphic.

Default Value:true

Method Details

addHandles(handleOrHandles, groupKey)inherited
Since: ArcGIS Maps SDK for JavaScript 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 }
);

// Handle gets removed when the object is destroyed.
this.addHandles(handle);
Parameters
handleOrHandles WatchHandle|WatchHandle[]

Handles marked for removal once the object is destroyed.

groupKey *
optional

Key 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.
fromJSON(json){*}static

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.
