Annotating Data Points
You can annotate data points in Bar, Line, and Bubble charts.
Context
You can pin a data point and add additional measures or comments to the pinned object. The pinned information is displayed as a Numeric point chart that is linked to the data point.
Note
You can annotate data points on Canvas pages only.If you filter the data, the annotated chart will not be affected. However, if you add another measure to your chart, you will break the link.
