Annotations are visual elements used to highlight certain areas on the plot. They can be used as comments or as markers for specific values on the plot. You can practically use any visual element as template for the annotation.

RadChart provides support for the following types of annotations:

  • Grid Line Annotations:

    • CartesianGridLineAnnotation: visually represented by a straight line accross the chart that marks a specific value on the associated cartesian axis.

    • PolarGridLineAnnotation: visually represented by a round line accross the chart that marks a specific value on the PolarAxis.

    • RadialGridLineAnnotation: visually represented by a straight line accross the chart that marks a specific angular value if associated with NumericalRadialAxis, or categorical value if associated with CategoricalRadialAxis.

  • Plot Band Annotations:

    • CartesianPlotBandAnnotation: visually represented by a band accross the chart that marks a specific range on the associated cartesian axis.

    • PolarPlotBandAnnotation: visually represented by a circular band accross the chart that marks a specific value (radius) range on the PolarAxis.

    • RadialPlotBandAnnotation: visually represented by an arc that marks a specific angular range if associated with NumericalRadialAxis, or categorical range if associated with CategoricalRadialAxis.

  • From-To Annotations:

  • Custom Annotations:

    • CartesianCustomAnnotation: this annotation marks a specific point on the cartesian chart. It requires its both horizontal and vertical coordinates to be specified.

    • PolarCustomAnnotation: this annotation marks a specific value on the polar chart. It requires its both radial and polar coordinates to be specified.

Here is a class hierarchy of the supported annotation types so you can get a better understanding of their structure and interdependencies:
