Notes

DataSource

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 parameter 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 imageicon to configure the field style.

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.

If the system response is delayed, you can click the imageicon on the right to view the data response result. You can also click the imageicon on the right to obtain the latest data of the widget. You can also click View Example to view an example of the response result of the current component.

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.
