Annotation
An Annotation is an explanatory image or text which can be anchored to a series point, a diagram coordinate (two axes values), or an arbitrary pixel coordinate on a chart’s surface.
Although annotations reside in the collection of the element to which they are anchored (chart, pane or series point), all annotations that are present in a chart control can be centrally accessed via its WebChartControl.AnnotationRepository property.
An annotation can be positioned either absolutely (by docking in a corner of its parent container), or relatively (by specifying the rotation angle and connector length to its anchor point).
The table below lists the main properties which affect the element’s appearance and functionality.
