Polar Chart with Annotations

Annotations are containers for images, text blocks, and custom content that display additional information about the visualized data.

To create annotations, populate the PolarChart's annotations array. Each object in the array configures an individual annotation. To specify settings for all annotations, use the commonAnnotationSettings object. Individual settings take precedence over common settings.

You can set each annotation's type property to "text", "image", or "custom". This demo shows only "text" annotations.

You can place annotations at specific coordinates or anchor them to PolarChart elements. This demo illustrates the following annotation placement methods:

• Angle and radius properties specify the position of annotations with season names.
• Annotations with temperatures are anchored to series points, and the offsetX, paddingTopBottom, and paddingLeftRight properties specify their position.

For more information on annotation settings, refer to the annotations[] help topic.
