Property Details

color

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

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

Default Value:"#000000"

declaredClass

Inherited
Property
declaredClass Stringreadonly
Inherited from Accessor

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

hoveredPoint

Property
hoveredPoint Pointreadonly

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

id

Property
id String

Unique identifier for the profile line.

progress

Property
progress Numberreadonly

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

samples

Property
samples ElevationProfileSample[]readonly

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

Property
statistics ElevationProfileStatisticsreadonly

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

Property
title String

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

type

Property
type Stringreadonly

The line type.

Possible Values:"ground" |"input" |"query" |"view"

viewVisualizationEnabled

Property
viewVisualizationEnabled Boolean
Since: ArcGIS Maps SDK for JavaScript 4.20 ElevationProfileLine 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

Method Overview

Show inherited methods Hide inherited methods
Name Return Type Summary Class

Adds one or more handles which are to be tied to the lifecycle of the object.

Accessor

Returns true if a named group of handles exist.

Accessor

Removes a group of handles owned by the object.

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");

Type Definitions

ElevationProfileSample

Type Definition
ElevationProfileSample Object

Represents an elevation sample in the profile.

Properties
x Number

The x coordinate of the sample, in the spatial reference of the view.

y Number

The y coordinate of the sample, in the spatial reference of the view.

z Number
optional

The z coordinate of the sample, in the spatial reference of the view.

distance Number

Horizontal (2D) distance from the beginning of the path, in the effective unit selected by the user. In geographic coordinate systems (GCS) and in WebMercator, the distance is the geodesic distance. In projected coordinate systems (PCS), apart from WebMercator, the distance is computed in a Euclidean manner (in the respective PCS).

elevation Number
optional

The elevation of the sample, in the effective units selected by the user.

ElevationProfileStatistics

Type Definition
ElevationProfileStatistics Object

Represents the statistics for the generated profile line.

Properties
maxDistance Number

The maximum horizontal (2D) distance of the path. In geographic coordinate systems (GCS) and in WebMercator, the distance is the geodesic distance. In projected coordinate systems (PCS), apart from WebMercator, the distance is computed in a Euclidean manner (in the respective PCS).

minElevation Number

The minimum elevation along the path.

maxElevation Number

The maximum elevation along the path.

avgElevation Number

The average elevation along the path.

elevationGain Number

The cumulative elevation gain along the path.

elevationLoss Number

The cumulative elevation loss along the path.

maxSlope Number

The maximum slope along the path. Profiles are sampled at a minimum distance of 10 meters (32.8 feet). Higher resolution profiles are downsampled to that minimum sampling distance before calculating the slope.

avgSlope Number

The average slope along the path. Profiles are sampled at a minimum distance of 10 meters (32.8 feet). Higher resolution profiles are downsampled to that minimum sampling distance before calculating the slope.
