Configure data items

Description

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 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.

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 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.

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.

Advanced Panel image

Enable this switch to associate global variables. When the slider interval changes, a data request is triggered and a temporary variable is emitted for use in other components. By default, the start and end values configured in the Data Source panel are displayed. For more information, see Component interaction configuration.

Blueprint Interaction

  1. Click the imageicon in the upper-left corner to go to the Blueprint page.

  2. On the Layer Nodes tab, add the widget to the main canvas.

  3. View blueprint configuration parameters. image.png

    • Event

      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.

      When the current interval changes

      The event that is thrown when the value of the current interval range changes, and the data item corresponding to the value. For more information, see the data example. 

      {
  "start": 2,
  "end": 6.5
}

    • Action

      Action

      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 request server data again. For more information, see the data example. 

      [
  {
    "start": 1,
    "end": 4.5
  }
]

      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.test and the data transferred to the request data interface is { id: '1'}, the final request interface is https://api.test?id=1.

      Obtain the value of the current range

      Gets the value of the interval in the current range. No parameters are required.

      Clear a component to its default value

      Clear the component data to the default value. No parameters are required.

      Move

      Move a widget to a specified location. For more information, see the data example. 

          {      
      // The positioning type. to indicates absolute positioning, whereas by indicates relative positioning. The default value is to. 
        "positionType": "to",
      // The location, which is indicated by the x and y coordinates. 
      "attr": {
        "x": 0,
        "y": 0
      },
      // The animation type. 
      "animation": {
        "enable": false,
        // The duration in which animation is displayed. 
        "animationDuration": 1000,
        // The animation curve, which can be set to linear|easeInOutQuad|easeInOutExpo. 
        "animationEasing": "linear"
      }
    }

      Switch Display /Display

      Toggles whether the widget is displayed or hidden. No parameters are required.

      Display
