A collection of annotations to add to the chart. The basic annotation allows adding custom labels or shapes. The items can be tied to points, axis coordinates or chart pixel coordinates.
General options for all annotations can be set using the
Highcharts.setOptions function. In this case only single objects are
supported, because it alters the defaults for all items. For initialization
in the chart constructors however, arrays of annotations are supported.
See more in the general docs.
