Gets a value indicating whether the test point is within the annotation.
true if the test point is within an annotation; otherwise, false.
The InAnnotation property is useful if you don't need to determine the exact element residing under the test point and are only interested in whether the point is within an annotation. For instance, the property can be used if you need to provide a common context menu for annotations regardless of which particular annotation element was right-clicked. If you need to obtain a particular element located under the test point, use the ChartHitInfo.HitTest property.
