aggregateGeometries

inherited Property

Type: Record<string, GeometryUnion> | null | undefined

Inherited from: Graphic

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

StatisticDefinition.statisticType

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

inherited Property

Type: any

Inherited from: Graphic

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

readonlyinherited Property

Type: string

Inherited from: Accessor

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

geometry

autocast inherited Property

Type: GeometryUnion | null | undefined

Inherited from: Graphic

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

readonlyinherited Property

Type: boolean

Inherited from: Graphic

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.aggregateIds the features comprising the cluster.

See also

Query.aggregateIds

Default value: false

layer

inherited Property

Type: GraphicLayer | null | undefined

Inherited from: Graphic

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

origin

inherited Property

Type: GraphicOrigin | null | undefined

Inherited from: Graphic

Returns information about the origin of a graphic if applicable. Origin details may be returned by methods such as MapView.hitTest() or by calling queryFeatures() on a layer or layer view. Depending on the origin type, this information may include the source layer or other origin-related metadata.

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
      });
    }
  })
});

popupTemplate

autocast inherited Property

Type: PopupTemplate | null | undefined

Inherited from: Graphic

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

getEffectivePopupTemplate()

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"
    }]
   }]
};

stackedAttributes

Property

Type: Record<string, any>[] | null | undefined

The stackedAttributes contains an array of name-value pairs, where the names correspond to unique values of the specified field or expression alias. Each name-value pair in the array represents a segment of the data, and these segments are stacked within the same bin. This allows for visualizing how different categories contribute to a total value. For example, it can be used to compare sales performance across different regions within the same time period.

symbol

autocast inherited Property

Type: SymbolUnion | null | undefined

Inherited from: Graphic

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:

Clone the symbol and change its properties.
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

inherited Property

Type: boolean

Inherited from: Graphic

Indicates the visibility of the graphic.

Default value: true
