To add a popover to a chart selection in a SAP Fiori application, you can follow these steps:
Identify the chart component in your SAP Fiori application where you want to add the popover.
Locate the event or callback that is triggered when a chart selection is made. This can vary depending on the chart library or framework you are using. For example, if you are using SAPUI5's sap.viz.ui5.controls.VizFrame control, you can listen to the selectData event.
In the event or callback handler, create an instance of the popover control you want to display. SAPUI5 provides a sap.m.Popover control that you can use for this purpose.
Customize the content of the popover as per your requirements. You can add any controls, text, or interactive elements inside the popover. For example, you can include charts, tables, or any other relevant information.
Attach the popover to the chart selection event. In the event or callback handler, you can open the popover when a chart selection is made.
Save your changes and run the SAP Fiori application. Now, when a chart selection is made, the popover will be displayed with the customized content.
By following these steps, you can add a popover to a chart selection in your SAP Fiori application, allowing you to display additional information or interactive elements related to the selected data.
