Comment
Application
A comment allows user to make a smaller, more targeted notation than a text box. The "point" on the comment also allows the notation to be placed much more specifically than a text box.
To add a сomment, place it on the chart and enter text for it. As with all text tools, you can edit the text of the сomment directly on the chart – you just need to click on the text field, and you can type.
Text
