  • 使用OWC 做图表时按周、月、年设置时间刻度是参数无效问题解决方法

    设置如下时间刻度:

     ChartAxisGroupingEnum.chAxisGroupingManual;
     ChartAxisUnitTypeEnum.chAxisUnitMonth;

    需要在SetData后面加上上面属性,否则会出现参数无效问题:

     InsertChart.SeriesCollection.Add(0);
                InsertChart.SeriesCollection[0].DataLabelsCollection.Add();
                InsertChart.SeriesCollection[0].DataLabelsCollection[0].HasValue = true;
                InsertChart.SeriesCollection[0].SetData(ChartDimensionsEnum.chDimSeriesNames, +(int)ChartSpecialDataSourcesEnum.chDataLiteral, "销售总额");
                InsertChart.SeriesCollection[0].SetData(ChartDimensionsEnum.chDimCategories, +(int)ChartSpecialDataSourcesEnum.chDataLiteral, strXdata);
                InsertChart.SeriesCollection[0].SetData(ChartDimensionsEnum.chDimValues, (int)ChartSpecialDataSourcesEnum.chDataLiteral, strYdata);

     InsertChart.Axes[0].GroupingType = OWC10.ChartAxisGroupingEnum.chAxisGroupingManual;
                InsertChart.Axes[0].GroupingUnitType = ChartAxisUnitTypeEnum.chAxisUnitMonth;
                InsertChart.Axes[0].NumberFormat = "yyyy-MM";
                InsertChart.Axes[0].GroupingUnit = 1;
