ChartAnchorPoint Class

Settings that indicate the Annotation is anchored to a chart.

Namespace: DevExpress.Xpf.Charts

Assembly: DevExpress.Xpf.Charts.v19.1.dll

Declaration

C#

public class ChartAnchorPoint :
    AnnotationAnchorPoint

VB.NET

Public Class ChartAnchorPoint
    Inherits AnnotationAnchorPoint

Remarks

The annotation position relative to the chart’s top and left edges can be specified using the ChartAnchorPoint.X and ChartAnchorPoint.Y properties. These coordinates position an annotation absolutely, meaning that the anchor point doesn’t change when a chart is being resized.

Example

This example demonstrates how to anchor an annotation to a chart surface point as shown in the following image:

To do this, specify the ChartAnchorPoint.X and ChartAnchorPoint.Y properties.
