ElevationProfileViewModel

Property Overview

Property Details

declaredClass Stringreadonly inherited

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

effectiveUnits EffectiveUnitsreadonly

Units which have been selected according to the magnitude of the elevations and distances that are to be displayed in the widget, according to the selected unit or unit system.

geodesicDistanceThreshold Number

When the spatial reference is projected (other than web mercator) and the path is shorter than this threshold, distances will be computed planimetrically. Otherwise distances will be computed geodetically.

Default Value:100000

highlightEnabled Boolean

Since: ArcGIS Maps SDK for JavaScript 4.20

Whether the graphic used as input is highlighted. The highlight color and opacity can be changed in highlightOptions.

Default Value:true

hoveredChartPosition Number

The position, in the range [0, 1], being hovered in the graph. We'll use this to determine which samples are being hovered and mark their position in the view.

input Graphicautocast

The input path along which elevation will be queried in order to generate an elevation profile.

Typically not set when creating the widget. In this case the widget starts empty, and waits for the user to either draw a new profile or generate a profile from selecting a line feature. The result of this action populates input. input can be set when constructing the widget, or set or changed at runtime. The input graphic must contain a geometry of type Polyline. Symbol and attributes of the input graphic are ignored.

profiles Collection<(ElevationProfileLineGround|ElevationProfileLineInput|ElevationProfileLineQuery|ElevationProfileLineView)>autocast

Collection of elevation profile lines which are to be generated and displayed in the widget's chart. See the different profile line types for details on usage and behavior.

Once an elevation profile is generated, each line will contain the raw data used to generate the chart and statistics. The order of the profiles within the collection determines the drawing order on the chart.

In a MapView ElevationProfileLineView is not supported.

progress Numberreadonly

The progress, between 0 and 1 of generating all the configured elevation profiles.

state Stringreadonly

The current state of the view model that can be used for rendering the UI of the widget.

Value	Description
disabled	widget is being created
ready	widget is ready. No path configured and no interactive operation ongoing.
creating	user is creating a new input path.
created	input path is configured but no interactive operation is ongoing.
selecting	user is selecting an existing input path.
selected	user selected an existing input path.

Possible Values:"disabled"|"ready"|"creating"|"created"|"selecting"|"selected"

Default Value:disabled

uniformChartScaling Boolean

Since: ArcGIS Maps SDK for JavaScript 4.20

Whether the chart should use a uniform scale for the X and Y axes. When a uniform scale is applied, the X axis will display the same distance units per pixel as the elevation units per pixel displayed in the Y axis.

unit SystemOrLengthUnit

Unit system (imperial, metric) or specific unit used for displaying the elevation and distance values.

unitOptions SystemOrLengthUnit[]

List of available units and unit systems (imperial, metric) for displaying the elevation and distance values.

view SceneView|MapView

A reference to the View.

Method Overview

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 }
);

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.

cancel()

Stops a creation/selection operation and restores the previously configured input path.

clear()

Clears the existing profile and stops any interaction.

hasHandles(groupKey){Boolean}inherited

Since: ArcGIS Maps SDK for JavaScript 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(groupKey)inherited

Since: ArcGIS Maps SDK for JavaScript 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");

start(options)

If mode is "sketch" (the default), switches to the "creating" state in which the user can draw a new line. If the mode is "select", switches to the "selecting" state and lets the user click on the view to select an existing line.

If any line is present, when the first point is drawn or an existing line is selected, the previous input is discarded.

Parameters

options Object optional Start options. Specification mode String optional Default Value: "sketch" The mode that the widget will start with. In "sketch" mode the user can draw a new line and in "select" mode the user can click on the view to select an existing line. Possible Values:"sketch"|"select"

stop()

Stops a creation/selection operation. If the current operation is a "sketch" and the input has at least two committed points (not being dragged), the input is kept. Otherwise the input is set to null.
