Comments on individual data point or visual

Hi sgupta22 

It's not natively available within Power BIfor data points, but there is a general comment feature for a dashboard or report .  But you can add comments in an Excel or SharePoint List and then show these comments in a Tooltip when you hover over the data. If you have the licence, you could build a Power App to collect the comments and even embed the Power App in the PBI Report

But the key here is structuring the Excel/SharePoint List correctly so that the comments show on the correct data.

You will need to think about the following possible dimensions, change to whatever is in your dataset

• Date
• Product/Country/ etc..

Load the data into Power BI, create relationships with your dimenesion tables. Create a tooltip page for the Comments

Here is a good video explaining. You don't need the visual they are promting to achieve what you need https://www.youtube.com/watch?v=MrpFQSB8NbY
