关键代码：

        /// <summary>
        /// 设置饼状图的Lable位置
        /// </summary>
        /// <param name="series">Series</param>
        /// <param name="lablePosition">PieSeriesLabelPosition枚举</param>
        public static void SetLablePosition(this Series series, PieSeriesLabelPosition lablePosition)
        {
            if (series.Label is PieSeriesLabel)
            {
                PieSeriesLabel _label = series.Label as PieSeriesLabel;
                _label.Position = lablePosition;
            }
            //if (series.Label is Pie3DSeriesLabel)
            //{
            //    Pie3DSeriesLabel _label = series.Label as Pie3DSeriesLabel;
            //    _label.Position = lablePosition;
            //}

        }
