Adding comments to a dashboard helps you store important explanations about it and convey your message and information regarding the dashboard to other users.
You can add comments to a dashboard in both the View Mode and the Edit Mode.
To add comments to a dashboard, follow the steps given below.

1. Open the Dashboard in edit mode or view mode. Refer to Editing a Dashboard or Viewing a Dashboard.
   The Dashboard is displayed.

2. On the function pane, in the top right corner, click Comment.
   The COMMENTS pane is displayed.

3. Type your comment in the Add comment field.

   Notes:

   Comments on dashboards currently do not support non-ASCII characters and some special characters like forward-slash, backward slash, and double inverted commas (" "). If any of these characters are present in the comment, they will be replaced with a single blank space. You can also use different formatting options that are available to format your comment. When mentioning a user in a comment, ensure that the user has access to the tenant where the dashboard is created.

   
   

4. Click the Send  icon.
   
   The comment is displayed in the same comment pane.
   
   
   Similarly, When you mention someone in the comment, that specific person will receive an email regarding the comment.
