如何在2d圖中標記Excel X軸和Y軸

我使用C＃在VS2010中創建Excel圖。這是一個2D XY散點圖。但我無法控制X軸的標籤！我只能控制Y軸的標籤！我花了太多時間試圖找出這個問題並放棄了。所以我正在尋找別人的幫助！這裏是我的代碼：

private void showExcelXY_v2() 
    { 
     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(Type.Missing); 
     ChartObject chartObj = chartObjs.Add(100, 20, 500, 300); 
     Microsoft.Office.Interop.Excel.Chart xlChart = chartObj.Chart; 

     //add some data from your datasource like a dataset or like below. 
     ws.Cells[1, 1] = "Value of n"; 
     ws.Cells[1, 2] = "Term"; 


     ws.Cells[2, 1] = "0"; 
     ws.Cells[2, 2] = "0"; 

     ws.Cells[3, 1] = "9181"; 
     ws.Cells[3, 2] = "0"; 

     ws.Cells[4, 1] = "9181"; 
     ws.Cells[4, 2] = "-377094"; 

     ws.Cells[5, 1] = "0"; 
     ws.Cells[5, 2] = "-377094"; 

     ws.Cells[6, 1] = "-9554"; 
     ws.Cells[6, 2] = "-329688"; 

     ws.Cells[7, 1] = "-9554"; 
     ws.Cells[7, 2] = "0"; 

     ws.Cells[8, 1] = "0"; 
     ws.Cells[8, 2] = "0"; 


     //set the source data and the chart type. 
     Range chartRange = ws.get_Range("A2", "B" + "8"); 
     xlChart.SetSourceData(chartRange, Type.Missing); 
     xlChart.ChartType = XlChartType.xlXYScatterLines; 

     // Customize axes: 
     Microsoft.Office.Interop.Excel.Axis xAxis = (Microsoft.Office.Interop.Excel.Axis)xlChart.Axes(XlAxisType.xlValue, XlAxisGroup.xlPrimary); 
     xAxis.HasTitle = true; 
     xAxis.AxisTitle.Text = "Above   Pressure (psi)   Below"; 

     Microsoft.Office.Interop.Excel.Axis yAxis = (Microsoft.Office.Interop.Excel.Axis)xlChart.Axes(XlAxisType.xlValue, XlAxisGroup.xlPrimary); 
     yAxis.MajorTickMark = XlTickMark.xlTickMarkCross; 
     yAxis.HasTitle = true; 
     yAxis.AxisTitle.Text = "Compression (lbf)"; 

     // Add title: 
     xlChart.HasTitle = true; 
     xlChart.ChartTitle.Text = "XPak Performance Envelope" + '\n' + "(Open Top & Bottom)"; 

     // Remove legend: 
     xlChart.HasLegend = false; 
    }

這段代碼的結果，你通過它一步，顯示了X軸標籤一直到Y軸，那麼它是由Y軸標籤覆蓋。什麼都沒有去X軸！任何想法將不勝感激。

您有兩個軸所定義的相同的方式：

xAxis = (Microsoft.Office.Interop.Excel.Axis)xlChart.Axes(XlAxisType.xlValue, XlAxisGroup.xlPrimary) 

yAxis = (Microsoft.Office.Interop.Excel.Axis)xlChart.Axes(XlAxisType.xlValue, XlAxisGroup.xlPrimary)

X軸是「類別」軸和y軸是「值」軸。嘗試這個爲x軸（修改）：

xAxis = (Microsoft.Office.Interop.Excel.Axis)xlChart.Axes(XlAxisType.xlCategory, XlAxisGroup.xlPrimary)

大衛，謝謝。你讓我度過這個噩夢！我不得不重新排列你的建議的順序，把它（XlAxisType.xlCategory，XlGroup.xlValue）接受，但這解決了我的問題！ – 2013-03-26 14:08:22
