Property Value

Type	Description
TdxChartHitTest	Stores HitTest information on the inspected point within the Chart control client area.

Remarks

HitTest information accessible through the HitTest property updates every time when:

• the OnHotTrackElement or OnMouseMove event occurs. The inspected point matches the current mouse pointer position.
• you call the CalculateHitTest procedure. The procedure’s X and Y parameters define the inspected point’s coordinates within the Chart control client area.

You can use HitTest.Point and HitTest.HitCode properties to obtain the inspected point’s position within the Chart control area and identify the type of the visual element to which the inspected point belongs.

Refer to the TdxChartHitTest class description for detailed information on available options.
