  Radius	The line width radius of the flying line.
  Dashed line solid line ratio	The ratio between dashed and solid segments of the flying line.
  Discontinuities	The number of discontinuities in the flying line.
  Speed	The animation speed of the flying line.
  Height	The height of the flying route above the ground plane.
  Radian	The radian of the flying line.
  Maximum Transparency	The maximum transparency of the flying route. Valid values: 0 to 1.
  Default Color	The default color of the flying routes.
  Type	Click the or icon on the right to add or delete a flight type. Click the or icon to configure the arrangement styles of multiple flying route types. Click the icon to copy the content of the currently selected flying route style configuration and add a flying route style with the same configuration. type: the type of the flying route, which matches the type field in the data panel. Color: the color of the flying routes.

• Icon Style: the style of the icon in the arc layer.

  Metric	description
  Custom Map	Move the pointer over the image and click Delete to delete the image. Then, click the image area or drag a local image to the area to add a sticker. Move the pointer over the image and click Change to upload the local image again. You can also enter the URL of an image to use a remote image as a custom sticker.

3. View blueprint configuration parameters.

   • Event

     Event	Description
     When the flight request is completed	After data of the flying routes layer is returned by the API and processed by filters, this event is triggered to pass JSON-format data. For specific data examples, see the Data Response Result section of the Data Source tab in the right-side configuration panel of the canvas editor.

   • Action

     Action	Description
     Request Flight	Requests the server data again. The data sent by an upstream data processing node or layer node is used as a parameter. For example, if the API data source is set to https://api.test and the data sent to the requesting a flying line action is { id: '1'}, the final request URL is https://api.test?id=1.
     Import flying lines	After widget data is processed in the required drawing format, it is imported for redrawing without requesting server data again. For specific data examples, see the Data Response Result section of the Data Source tab in the right-side configuration panel of the canvas editor.
     Switch Display /Hide	Toggles the visibility of the 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 widget configuration data. Then, modify the style field for the data processing node in Blueprint Editor.
