	/// The sticks run from the zero value of the Y axis, to the Y point defined in each
	/// <see cref="PointPair"/> of the <see cref="IPointList" /> (see <see cref="CurveItem.Points"/>).
	/// The properties of the sticks are defined in the <see cref="Line"/> property.
	/// Normally, the <see cref="Symbol"/> is not visible.  However, if you manually enable the
	/// <see cref="Symbol"/> using the <see cref="ZedGraph.Symbol.IsVisible"/> property, the
	/// symbols will be drawn at the "Z" value from each <see cref="PointPair" /> (see
	/// <see cref="PointPair.Z" />).
