ElevationProfileLineView | API Reference | ArcGIS Maps SDK for JavaScript 4.31

Profile line which samples elevation directly from the SceneView.

All volumetric objects in a SceneView contribute to the resulting profile, including Ground, SceneLayer, IntegratedMeshLayer, IntegratedMesh3DTilesLayer, and FeatureLayers with volumetric 3D symbols (e.g. ObjectSymbol3DLayer, PathSymbol3DLayer). The input graphic itself is excluded when the profile is generated. When the Camera changes, the profile line will be updated to reflect what is currently visible in the view.

This profile line type is not supported in a MapView.

The purple building profile is the result of a profile line of type view.

Example

const elevationProfile = new ElevationProfile({
  view: view,
  profiles: [{
    type: "view"
  }]
});

Property Details

color Property color Colorautocast Autocasts from Object|Number []|String

Color of the line on the chart and in the view.

Default Value:"#cf4ccf"

declaredClass Inherited Property declaredClass Stringreadonly Inherited from Accessor

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

Items which are to be excluded when querying elevation from view.

hoveredPoint Inherited Property hoveredPoint Pointreadonly Inherited from ElevationProfileLine

Point being hovered in the chart, in the view's spatial reference.

id Inherited Property id String Inherited from ElevationProfileLine

Unique identifier for the profile line.

Items which are to be hit when querying elevation from view.

progress Inherited Property progress Numberreadonly Inherited from ElevationProfileLine

How far along the generation of this profile is. 0 means nothing was loaded and 1 means loading is complete.

samples Inherited Property samples ElevationProfileSample[]readonly Inherited from ElevationProfileLine

List of samples that make up the elevation profile. It can be passed to a graphing library in order to display the profile in 2D.

statistics Inherited Property statistics ElevationProfileStatisticsreadonly Inherited from ElevationProfileLine

Statistics about the generated elevation profile, if available.

For slope computations, profiles are sampled at a minimum distance of 10 meters (32.8 feet). Higher resolution profiles are downsampled to a 10-meter (32.8-foot) sampling distance before calculating the slope.

title Inherited Property title String Inherited from ElevationProfileLine

Title of the line, to be displayed in the chart tooltip and in the chart legend.

type Property type Stringreadonly

The line type.

For ElevationProfileLineView the type is always "view".

viewVisualizationEnabled Property viewVisualizationEnabled Boolean Since: ArcGIS Maps SDK for JavaScript 4.20 ElevationProfileLineView since 4.18, viewVisualizationEnabled added at 4.20.

Whether a line visualization representing elevationSamples should be added to the SceneView. This property doesn't apply to MapView.

Default Value:true

visible Inherited Property visible Boolean Inherited from ElevationProfileLine

Whether the line should be computed and shown in the chart.

Default Value:true

Return Type	Summary	Class
	Adds one or more handles which are to be tied to the lifecycle of the object.	Accessor
Boolean	Returns true if a named group of handles exist.	Accessor
	Removes a group of handles owned by the object.	Accessor

Method Details

addHandles Inherited Method addHandles(handleOrHandles, groupKey) Inherited from Accessor 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

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.

hasHandles Inherited Method hasHandles(groupKey){Boolean} Inherited from Accessor Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, hasHandles added at 4.25.

Returns true if a named group of handles exist.

Parameter

groupKey *

optional

A group key.

Returns

Type	Description
Boolean	Returns `true` if a named group of handles exist.

Example

// Remove a named group of handles if they exist.
if (obj.hasHandles("watch-view-updates")) {
  obj.removeHandles("watch-view-updates");
}

removeHandles Inherited Method removeHandles(groupKey) Inherited from Accessor Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, removeHandles added at 4.25.

Removes a group of handles owned by the object.

Parameter

groupKey *

optional

A group key or an array or collection of group keys to remove.

Example

obj.removeHandles(); // removes handles from default group

obj.removeHandles("handle-group");
obj.removeHandles("other-handle-group");
