Parameter	Description
Show top face	Turn on the Show top face switch to set the color of the top face. Turn off the Show top face switch to hide the top face color settings.
Top face color	Set the color of the top face. This option is available only when the Show top face switch is on. For more information, see Color picker to change the color.
Side face color	Set the color of the side faces. For more information, see Color picker to change the color.
Side face gradient	Turn on the switch to apply a gradient to the side face color. Turn off the switch to use a solid color.
Side face texture	In the Texture style area: Hover over the image and click Delete to remove the current texture. Then, click the image area or drag a local image into the area to add a new side face texture. Hover over the image and click Change to upload a different local image. You can also enter a texture URL to use an image from a remote server as the side face texture. Note Textures must be in PNG or JPG format. Texture color: Set the color of the side face texture. For more information, see Color picker to change the color. UV tiling value: Adjust the UV tiling value of the side face texture on the x-axis and y-axis.
Side face overlay texture	In the Texture style area: Hover over the image and click Delete to remove the current texture. Then, click the image area or drag a local image into the area to add a new side face overlay texture. Hover over the image and click Change to upload a different local image. You can also enter a texture URL to use an image from a remote server as the side face overlay texture. Note Textures must be in PNG or JPG format. UV tiling value: Adjust the UV tiling value of the side face overlay texture on the x-axis and y-axis.

Animation: Geo-fence animation configuration parameters.

Parameter

Description

Animation mode

Set the animation mode for the geo-fence. Options are Horizontal and Vertical.

Movement speed

Set the movement speed of the geo-fence.

Side face texture: Drag the slider to set the movement ratio of the side face texture. The value can range from 0 to 0.5.
Side face overlay texture: Drag the slider to set the movement ratio of the side face overlay texture. The value can range from 0 to 0.5.

Interaction: Geo-fence interaction configuration parameters.

Parameter	Description
Mouse click	Turn on the switch to enable mouse click interactions. Turn off the switch to disable them.
Highlight color	Set the highlight color for the fence. For more information, see Color picker to change the color.
Callback ID	Set the callback ID for the geo-fence.

Data panel

Field	Description
id	The ID of the geo-fence.
callback	The callback ID of the geo-fence.
geometry	The geometry coordinate value of the geo-fence.
colorField	The color of the geo-fence.

Configuration Item	Description
Controlled Mode	Turn on the switch to prevent the widget from requesting data upon initialization. Data is requested only through a callback ID or a method configured in the blueprint editor. Turn off the switch to allow automatic data update requests. The switch is off by default.
Automatic Update Request	Select this option to enable dynamic polling and manually set the polling frequency. If you clear this option, data is not updated automatically. You must manually refresh the page or trigger data update requests using the blueprint editor or callback ID events.
Data Source	Click Configure Data Source. In the Set Data Source panel, you can modify the data source type and data query code, preview the data source return results, and view the data response.
Data Result	Displays the response result of a data request. When the data source changes, click the icon on the right to view the real-time data response.

Note

You can also use the layer data API as a block data API to configure more data source types in the data dashboard or to interact with data from common chart widgets. For more information, see One-click generation of block APIs.

If you created your 3D City Builder project in Spatial Data Project mode and the project contains data primitive layer content, you can use the Spatial Build Data Source to obtain spatial map data when you configure the data panel in the scene editor. The steps are as follows:

In the layer configuration panel, select the Data tab. Click the Data Source Type drop-down list at the bottom of the panel and select Spatial Build Data Source.
From the Data Project drop-down list at the bottom of the panel, select an existing data project from the spatial build platform.
After you select a data project, select a matching dataset from the Dataset drop-down list.

Note
If no configurable data types are available for the Data Project and Dataset configuration items, click Go to Spatial Build Platform to Manage Data in the panel to configure data in the spatial build platform. For more information, see Overview of spatial data management.

Blueprint interaction

In the layer list on the left side of the Scenario Editor page, click the icon next to Geo-fences.
Click the icon in the upper-left corner of the page.

On the Blueprint Editor page, click the Geo-fence layer in the Import Nodes section. The configuration parameters for the Geo-fence layer appear on the canvas, as shown in the following figure.

Events

Event	Description
When data API request is complete	An event that is triggered after the data API request returns a response and the response is processed by the filter. The event also returns the processed data in JSON format. For a data example, see the Data response section on the Data tab of the widget's configuration panel in the canvas editor.
Left-click	An event that is triggered when you left-click the geo-fence. It returns the click position and the raw data item.

Actions

Action	Description
Request data API	Requests server-side data again. Data provided by input data processing nodes or layer nodes is used as parameters. For example, if a geo-fence is configured with an API data source of `https://api.test` and the data passed to the Request data API action is `{ id: '1'}`, the final request URL is `https://api.test?id=1`.
Import data API	Processes data in the component's drawing format and then imports the data to redraw the component. This action does not request server-side data again. For data examples, see the Data Response area on the Data tab in the component's configuration panel in the canvas editor.
Show component	Shows the component. No parameters are required.
Hide component	Hides the component. No parameters are required.
