Data dashboard

Interactive Panel

Select the Enable check box to enable interactions between widgets. When you click a column of an arc column chart, a data request is triggered, a callback value is thrown, and data of different columns is dynamically loaded. By default, the x value in the data is returned. For more information, see Component interaction configuration.

Blueprint Interaction

1. In the canvas editor, right-click a widget in the layer pane and select Export to Blueprint Editor.

2. Click the icon in the upper-left corner of the page.

3. In Blueprint Editor, click the Arc Column Chart widget in the Import Nodes pane. You can view the parameters of the Arc Column Chart widget on the canvas, as shown in the following figure.

   • Event

     Event	Description
     When the arc column chart interface description 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 tab in the right-side configuration panel of the canvas editor.
     When the arc column chart interface description request fails	The event that is returned when a data interface request fails (such as network problems or interface errors) and is processed by the filter. The event also throws the processed JSON data. For more information about specific data examples, see the Data Response Result section of the Data tab in the right-side configuration panel of the canvas editor.
     When a data item is clicked	The event that is raised when a column of the column chart is clicked, along with the data item corresponding to the column.

   • Action

     Action	Description
     Description of the request arc column chart operation	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 passed to the Request Arc Column Description action is { id: '1'}, the final request interface is https://api.test?id=1.
     Import Circular Column Chart Interface Description	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 of the Data tab in the right-side configuration panel of the canvas editor.
