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;
