 ChSeries objSeries1 = objChart.SeriesCollection.Add(0);
                ChSeries objSeries2 = objChart.SeriesCollection.Add(0);
                objSeries1.Type = ChartChartTypeEnum.chChartTypeColumnClustered;

                seAxes.Title.Font.Size = 8;
               //seAxes.Title.Position = ChartTitlePositionEnum.chTitlePositionRight;
                               
               
               //给定series的名字
                objSeries2.SetData(ChartDimensionsEnum.chDimSeriesNames,+(int) ChartSpecialDataSourcesEnum.chDataLiteral, "%");

               //  +(int)ChartSpecialDataSourcesEnum.chDataLiteral, "％");
                //计算数据   
                /*categories   和   values   可以用tab分割的字符串来表示*/
                string strSeriesName = "DPPM";
                string strSeriesName1 = "LAR";

怎么设置给定的series的名字放在上面显示呢，默认在右边。
