Gets a value indicating whether the test point is within the constant line.
true if the test point is within a constant line; otherwise, false.
The InConstantLine 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 a constant line. For instance, the property can be used if you need to provide a common context menu for a constant line regardless of which particular constant line element was right-clicked. If you need to obtain a particular element located under the test point, use the ChartHitInfo.HitTest property.
