	 ' Initialize the Vertical Line.
	DrawingInitialize(symbolIndex, 2)

	 ' Get the X value of core point 0.
	Define x1 As Integer = DrawingCorePointBarIndex(0)
	 ' Get the Y value of core point 0.
	Define y1 As Number = DrawingCorePointValue(0)
	 ' Get the X value of core point 1.
	Define x2 As Integer = DrawingCorePointBarIndex(0)
	 ' Get the Y value of core point 1.
	Define y2 As Number = DrawingCorePointValue(1)
	 ' Reset core point 1 with the X value of core point 0.
	DrawingSetCorePoint(1, x2, y2)
	DrawingSetLine(0, x1, y1, "", x2, y2, "")
