Question

我在一个chartspace上画了三个图，分别给三个图表设置了chDimCategories值，但运行结果三个图的横坐标都是同样的，希望大家都帮帮忙.
  #region 添加系别图表名称 A
            //添加系别图表名称
            mChSeries[0].SetData(OWC10.ChartDimensionsEnum.chDimSeriesNames,
                OWC10.ChartSpecialDataSourcesEnum.chDataLiteral.GetHashCode(), "speed");
            //给定系别图表分类
            mChSeries[0].SetData(OWC10.ChartDimensionsEnum.chDimCategories,
                OWC10.ChartSpecialDataSourcesEnum.chDataLiteral.GetHashCode(), "<5,<40,<60,<68,<77,<83,<88,<92,<144,>144");
            //给定系别图表值
            mChSeries[0].SetData(OWC10.ChartDimensionsEnum.chDimValues,
                OWC10.ChartSpecialDataSourcesEnum.chDataLiteral.GetHashCode(),
               SysManageDataSet.GetColumnData(SysManageDataSet.Categories(SysManageDataSet.ReportType.T1,
                 SysManageDataSet.FiledName.Speed), SysManageDataSet.ExpReport.speed));
            #endregion            #region 添加系别图表名称 B
            //添加系别图表名称
            mChSeries[1].SetData(OWC10.ChartDimensionsEnum.chDimSeriesNames,
                OWC10.ChartSpecialDataSourcesEnum.chDataLiteral.GetHashCode(), "engine");
            //给定系别图表分类
            mChSeries[1].SetData(OWC10.ChartDimensionsEnum.chDimCategories,
                OWC10.ChartSpecialDataSourcesEnum.chDataLiteral.GetHashCode(), "<100,<200,<500");
            //给定系别图表值
            mChSeries[1].SetData(OWC10.ChartDimensionsEnum.chDimValues,
                OWC10.ChartSpecialDataSourcesEnum.chDataLiteral.GetHashCode(),
               SysManageDataSet.GetColumnData(SysManageDataSet.Categories(SysManageDataSet.ReportType.T1,
                 SysManageDataSet.FiledName.engine), SysManageDataSet.ExpReport.engine));
            #endregion
           
            #region 添加系别图表名称 C
            //添加系别图表名称
            mChSeries[3].SetData(OWC10.ChartDimensionsEnum.chDimSeriesNames,
                OWC10.ChartSpecialDataSourcesEnum.chDataLiteral.GetHashCode(), "Fuelconsumption");
            //给定系别图表分类
            mChSeries[3].SetData(OWC10.ChartDimensionsEnum.chDimCategories,
                OWC10.ChartSpecialDataSourcesEnum.chDataLiteral.GetHashCode(), "<1,<2,<5,<8,<77,<83,<88,<92,<144,>144");
            //给定系别图表值
            mChSeries[3].SetData(OWC10.ChartDimensionsEnum.chDimValues,
                OWC10.ChartSpecialDataSourcesEnum.chDataLiteral.GetHashCode(),
               SysManageDataSet.GetColumnData(SysManageDataSet.Categories(SysManageDataSet.ReportType.T1,
                 SysManageDataSet.FiledName.Fuelconsumption), SysManageDataSet.ExpReport.Fuelconsumption));
            #endregion
