For more information, see the color picker description. DataV calculates the cell where the point is located based on the longitude and latitude of the point in the data. The cell with the largest number of points is the cell with the largest number of points. Color Classifications: the number of color levels of the honeycomb heat layer. Used in conjunction with the MinValue Color and MaxValue Color configuration items to set the color of each honeycomb according to the distribution of points. Note The colors between the MaxValue Color and the MinValue Color are displayed based on the number of Color Classifications that you set.
  Shadow	Sets the color of the honeycomb shadow and the extent range of shadow blur.

Data Source	In the right-side panel of Canvas Editor, click the Data tab. Click Set next to Static Data. In the Configure Datasource panel, select a data source from the Data Source Type drop-down list. Enter code for data query in the code editor, click Preview Data Response to preview the response of the data source, and then view the response. For more information, see Configure widget data.
Data Filter	If you select the Data Filter check box, you can convert the data structure, filter data, and perform simple calculations. If you click the plus sign (+) next to Add Filter, you can configure the script for the data filter in the editor that appears. For more information, see Use the data filter.

   • Event

     Event	Description
     On Completion of Data Interface Request	The event is triggered with the processed JSON data after a data interface request is responded and processed by a filter. For more information about specific data examples, see the Data Response Result section on the Data tab of the canvas editor.
     On Failure of Data Interface Request	When a data interface request fails (the request may be caused by network problems or interface errors, etc.), the event is returned and processed by the filter, and the processed JSON-formatted data is also thrown. For more information about specific data examples, see the Data Response Result section on the Data tab of the canvas editor.

   • Action

     Action	Description
     Request Data Interface	This action is performed to request 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 configured for the cellular thermal layer as http://api.test and the data passed to the Request Data Interface action is { id: '1'}, the final request interface is http://api.test?id=1.
     Import Data Interface	After data of a widget is processed in accordance with its drawing format, the widget is imported for redrawing. You do not need to request server data again. For more information about specific data examples, see the Data Response Result section on the Data tab of the canvas editor.
