Custom Point Annotations

A number of custom point annotations definitions are available for a Cartesian graph that allows you the flexibility to annotate any point of interest on the graph.

On the Cartesian context tab, on the Measure tab, on the Custom annotations group, click the  Points icon. From the drop-down list, select the type of annotation you want to use.
