示例1: DrawSingleBar
/// <summary>
/// Protected internal routine that draws the specified single bar (an individual "point")
/// of this series to the specified <see cref="Graphics"/> device.
/// </summary>
/// <param name="g">
/// A graphic device object to be drawn into. This is normally e.Graphics from the
/// PaintEventArgs argument to the Paint() method.

/// <param name="pane">
/// A reference to the <see cref="GraphPane"/> object that is the parent or
/// owner of this object.
/// </param>
/// <param name="curve">A <see cref="CurveItem"/> object representing the

/// <param name="index">
/// The zero-based index number for the single bar to be drawn.
