Annotations are floating text you can position on your chart to write key points.
Click on your chart or map in the editor
Select “Annotations & Refrences” → Add Annotation
An annotation will appear on your chart. You can click on it to enter edit mode, and then drag it around.
You can edit the annotation text, orientation, line type, line end, font style and color.
An annotation is a great tool to explain your chart and make it easier for the readers to understand your main message.
