Click the data response result to view the data field code. Click View Example to see the array type and sample code that the data source accepts. You can write your fields based on the example. Other data request configurations: Disable Loading State: If you check this box, the widget's initial loading content does not appear when the widget updates or when you preview the data dashboard. Controlled Mode: If you check this box, the widget does not request data when it initializes. Data requests can only be started by the blueprint editor or by global variable events. Auto Update Request: If you check this box, the platform polls for data updates at the interval you set. If you do not check this box, you must refresh the page manually or use the blueprint editor or global variable events to trigger data updates.
