Hi Louis,
Per your description, my understand is you want to have the Data Labels for the Pivot Chart as percentage and currency which means you need to format the data labels in the Pivot Chart. If yes, please follow the below steps:
Open the Excel file with Pivot Chart and enabled with Data Labels> Click on the Labels displayed in the Chart> Right-click> Click Format Data Labels> Label Options> Number> In the Category, select the format as per your requirement.
Here is the reference article: Change the format of data labels in a chart.
If my understanding is wrong, we’re sorry and please provide the screenshots for better understanding your situation.
Appreciate your understanding and stay safe 😊
Best Regards,
Chitrahaas
