PlotBand Annotation Types

Updated on Mar 26, 2026

In this article the properties of the PlotBandAnnotations are described depending on the type of axis the annotation is associated with - cartesian, polar or radial.

PlotBand Annotation Properties

The common properties for all PlotBandAnnotations are:

• Fill: Gets or sets the Brush that specifies how the shape's interior is painted.
• StrokeDashArray: Gets or sets a collection of double values that indicates the pattern of dashes and gaps that is used to outline stroked annotation.
• Stroke: Gets or sets the Brush that specifies how the shape outline is painted.
• StrokeThickness: Gets or sets the width of the shape stroke outline.

CartesianPlotBandAnnotation Specific Properties

• Axis: The cartesian plotband annotation needs to be associated with the horizontal or vertical axis explicitly.

• From (of type object): The starting value for the plotband.

  When the axis is numerical (Linear or Logarithmic) a numeric value is expected, and when it is a CategoricalAxis - a category is expected.

• To (of type object): The ending value for the plotband.

  When the axis is numerical (Linear or Logarithmic) a numeric value is expected, and when it is a CategoricalAxis - a category is expected.

• Label (string): The string that defines the label of the annotation. By default it is null.

• LabelDefinition (ChartAnnotationLabelDefinition): Defines the position of the annotation label. Check the Annotation Labels topic for more details.

PolarAxisPlotBandAnnotation Specific Properties

• From (of type double): The starting point for the plotband.
• To (of type double): The ending point for the plotband.

RadialAxisPlotBandAnnotation Specific Properties

• From (of type object): The starting point for the plotband.

  When the radial axis is a NumericalRadialAxis a numeric value is expected, and when it is a CategoricalRadialAxis - a category.

• To (of type object): the ending point for the plotband.

  When the radial axis is a NumericalRadialAxis a numeric value is expected, and when it is a CategoricalRadialAxis - a category.

Example of CartesianPlotBandAnnotations

CartesianPlotbandAnnotation can be either a horizontal or a vertical stripe that crosses the whole chart and marks a value range on the associate axis. Example 1 demonstrates how to define both a horizontal and vertical CartesianPlotBandAnnotation in a RadCartesianChart.

Example of PolarAxisPlotBandAnnotation

PolarAxisPlotBandAnnotation is represented by concentric stripe that mark a specific value (radius) range on the polar axis. Example 2 demonstrates how to define PolarAxisPlotBandAnnotation in a RadPolarChart.

Example of RadialAxisPlotBandAnnotation

RadialAxisPlotBandAnnotation is represented by a sector of the circle (pie slice) that marks specific angular/categorical range. Example 3 demonstrates how to define a RadialAxisPlotBandAnnotation in a RadPolarChart.
