Excel圖表+ C＃

Question

我使用excel從c＃繪製圖表，但我需要圖表爲一個相互關聯的系列而不是兩個系列（當我選擇一個範圍有兩列數據時）
可以任意一個幫助：

 xla.Visible = true; 
     Workbook wb = xla.Workbooks.Add(XlSheetType.xlWorksheet); 
     Worksheet ws = (Worksheet)xla.ActiveSheet; 

     // Now create the chart. 
     ChartObjects chartObjs = (ChartObjects)ws.ChartObjects(Type.Missing); 
     ChartObject chartObj = chartObjs.Add(100, 20, 300, 300); 
     Chart xlChart = chartObj.Chart; 
     Range rg = ws.get_Range("B2", "C17"); 
     xlChart.SetSourceData(chartRange, XlRowCol.xlColumns); 

感謝

我打掃碼了一點，並添加隨機數據的產生，所以這應該獨立運行。

Random random = new Random(); 
Microsoft.Office.Interop.Excel.Application xla = new Microsoft.Office.Interop.Excel.Application(); 
xla.Visible = true; 
Workbook wb = xla.Workbooks.Add(XlSheetType.xlWorksheet); 

Worksheet ws = (Worksheet)xla.ActiveSheet; 

// Now create the chart. 
ChartObjects chartObjs = (ChartObjects)ws.ChartObjects(); 
ChartObject chartObj = chartObjs.Add(150, 20, 300, 300); 
Chart xlChart = chartObj.Chart; 

// generate some random data 
for (int row = 0; row < 16; row++) 
{ 
    ws.Cells[row + 2, 2] = row + 1; 
    ws.Cells[row + 2, 3] = random.Next(100); 
} 

Range xValues = ws.Range["B2", "B17"]; 
Range values = ws.Range["C2", "C17"]; 

SeriesCollection seriesCollection = xlChart.SeriesCollection(); 

Series series1 = seriesCollection.NewSeries(); 
series1.XValues = xValues; 
series1.Values = values;
