我希望Excel看起来像这样:
我必须尝试创建工作簿和工作表,而不是添加图表并从另一个图表获取范围 对于下一步,我想显示多个在一个图表中看起来像这样的线图 但就目前而言,我只是不知道该怎么做
这是我的代码,也是我尝试过的:
但是我有一个错误
System.Runtime.InteropServices.COMException: 'Exception from HRESULT: 0x800A03EC'
我尝试了其他方法,但在所有情况下都遇到此错误...
我没有找到任何例子。
而且我认为,在随机尝试中,我永远不会找到正确的方法来做到这一点...

reportWorksheet.Cells[i, "A"] = c;
v += vDiff;

Worksheet ChartWorksheet = reportWorkbook.Worksheets.Add();
Range chartRange;

ChartObject myChart = (ChartObject)xlCharts.Add(10, 80, 300, 250);
Chart chartPage = myChart.Chart;
chartRange = ChartWorksheet.get_Range("'Sheet2'!A1", "'Sheet2'!B29");
chartPage.SetSourceData(chartRange);
//chartPage.ChartType = Excel.XlChartType.xlLine;
chartPage.ChartType = XlChartType.xlLine;
}
}
}

代替使用此
chartRange = ChartWorksheet.get_Range("'Sheet2'!A1", "'Sheet2'!B29");
使用以下代码选择范围
chartRange = reportWorksheet.get_Range("A1","B39");
您应该使它正常工作。
要使Volt处于一边,请尝试以下操作:
Worksheet ChartWorksheet = reportWorkbook.Worksheets.Add();
ChartWorksheet = reportWorkbook.ActiveSheet;
ChartObjects xlCharts = (ChartObjects)ChartWorksheet.ChartObjects(Type.Missing);
ChartObject myChart = (ChartObject)xlCharts.Add(10, 80, 300, 250);
Chart chartPage = myChart.Chart;
SeriesCollection oSeriesCollection = (SeriesCollection)myChart.Chart.SeriesCollection();
Series Data = oSeriesCollection.NewSeries();
Data.XValues = reportWorksheet.get_Range("A2", "A29");
Data.Values = reportWorksheet.get_Range("B2", "B29");
Data.Name = "Volt";
chartPage.ChartType = XlChartType.xlLineMarkers;
渲染的输出:
