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 sampling distance of 10m (32.8ft). Higher resolution profiles are downsampled to a 10m (32.8ft) sampling distance before the slope is calculated.

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

visible Property visible Boolean

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");

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

Distance from the beginning of the path, in the effective selected by the user.

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 distance or length of the path.

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. Slope is calculated by sampling over a distance of 10m (32.8ft) or more.

avgSlope Number

The average slope along the path. Slope is calculated by sampling over a distance of 10m (32.8ft) or more.
