Linear Gradient Scatter Layer

Chart style

The scatter layer (linear gradient) is a subcomponent of 3D Earth that supports independent style and data configurations, including scatter size, color, type, longitude, and latitude. It displays point data at geographic locations as scatter points.

Style Panel

• Search Configuration: Click the Search configuration items icon in the upper-right corner of the Style panel. In the Search Configuration panel, enter the name of the configuration items that you want to search for and locate the configuration items. Fuzzy match is supported. For more information, see Search configuration items.

• Height: the height of the scatter layer relative to the spherical surface of the map. Valid values: 3 to 10.

• Minimum Radius: the minimum radius of the scatter.

• Maximum Radius: the maximum radius of the scatter.

  Note

  The scatter radius is interpolated between the minimum and maximum radius based on the value field.

• Animation Speed: the animation speed of the scattered dots. Valid value: 0 to 0.1.

• Transparency: the transparency of the scatter layer. Valid values: 0 to 1.

• Scatter Map: the map style of the scatter layer. You can paste the map URL to obtain the map.

• Default Color: If the type field in the data is inconsistent with the scatter type configuration items, the scatter is displayed in the default color.

• Scatter Type: Click the or icon to add or delete a scatter type. Click the or icon to configure the arrangement style of multiple scatter points. Click the icon to copy the currently selected scatter pattern configuration and add a scatter pattern with the same configuration.

  Metric	description
  type	The value of the type corresponds to the type field in the data.
  Color	The color of the scatter for this type. Note You can configure multiple color series. Points are rendered using the color that matches their type field. If a point's type is not listed in the Scatter Type pane, the default color is used.

   • Event

     Event	Description
     When the scatter layer request is completed	Triggered after a data request is responded to and processed by a filter. The processed JSON data is passed as the event payload. For data examples, see the Data Response Result section of the Data Source tab in the right-side configuration panel.

   • Action

     Action	Description
     Request Scatter Layer	Requests server data again, using the data from an upstream data processing node or layer node as a parameter. For example, if the API data source is https://api.test and the data passed to the request scatter layer action is { id: '1'}, the final request URL is https://api.test?id=1.
     Import Scatter Layer	Imports pre-processed data in the widget's drawing format for redrawing without requesting server data again. For data examples, see the Data Response Result section of the Data Source tab in the right-side configuration panel.
     Switch Display /Hash	Specifies whether to show or hide a widget. No parameters are required.
     Display	Display the widget. For more information, see Data example. { "animationType": "",// The animation method. Valid value: fade. If you do not specify this parameter, no animation is generated. "animationDuration": 1000,// The animation delay. Unit: ms. "animationEasing": ""// animation curve }
     Hide	Hide the component. For more information, see Data example. { "animationType": "",// The animation method. Valid value: fade. If you do not specify this parameter, no animation is generated. "animationDuration": 1000,// The animation delay. Unit: ms. "animationEasing": ""// animation curve }
     Update component configurations	Dynamically updates widget style configurations. In the Style panel, click Copy Configuration to Clipboard to obtain the configuration data. Then modify the style field for the data processing node in Blueprint Editor.
