You can set each annotation's type property to "text", "image", or "custom". Depending on the type, specify the text or image property. You can also add a description that will be displayed in a tooltip.
Annotations can be unattached or anchored to a chart element. In this demo, all annotations are anchored to series points via the argument and series properties. Refer to the annotations description for more information on how to position annotations.
