This topic describes the meaning of each configuration items in the Mesh aggregation layer.
Chart style
The grid aggregation layer is a sub-component of the basic flat map 4.0. It supports independent styles and data configurations, including the size, color, and labeling of the grid, and can represent the distribution density of points in geographic locations in the form of aggregated grid points.

Data sources | You can use the code editor or visual editor to view the data fields contained in the widget. You can also modify the data type to flexibly configure the component data. |
Data Mapping | If you need to customize chart field configurations, you can set different field mapping content in the Data Mapping module and field mapping these content to the corresponding fields of the widget. This allows you to match data without modifying the fields in the data source. You can also click the |
Configure a filter | Turn on Filter, select an existing data filter or create a data filter, and configure a data filter script to filter data. For more information, see Manage data filters. |
Data Response Result | The Data Response Result section displays widget data in real time. If the data source of the widget changes, this section displays the latest data. If the system response is delayed, you can click the |
Forbid Loading | If you select the check box, you will not see the loaded content during component initialization when you update the component and preview the data kanban. If you select the check box, the opposite is true. By default, the status is deselected. |
Controlled Mode | If you select the check box, the component does not request data in the initialized state, and only requests data by using global variables or the method configured in Blueprint Editor. If you clear the check box, you can use automatic update to request data. By default, the status is deselected. |
Auto Data Request | Select the check box to manually enter the time frequency of polling to set dynamic polling. If you clear the page, the page is not automatically updated. You need to manually refresh the page or use Blueprint Editor and global variable events to trigger a request to update data. |

Event
Description
When the data interface request is completed
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 of the Data Source tab in the right-side configuration panel of the canvas editor.

Description
Import data
After data of a widget is processed in accordance with its drawing format, the widget is imported for redrawing. You do not need to re-request server data. View data examples.
[ { "lng": 126.75, "lat": 42.95, "value": 22 } ]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
https://api.testand the data passed to the request data interface is{ id: '1'}, the final request interface ishttps://api.test?id=1.Toggle Display
Specifies whether to show or hide a widget. No parameters are required.
Display
Display the widget. For more information, see Data example.
