如何在2d图中标记Excel X轴和Y轴

我使用C＃在VS2010中创建Excel图。这是一个2D XY散点图。但我无法控制X轴的标签！我只能控制Y轴的标签！我花了太多时间试图找出这个问题并放弃了。所以我正在寻找别人的帮助！这里是我的代码：

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; 
    }

这段代码的结果，你通过它一步，显示了X轴标签一直到Y轴，那么它是由Y轴标签覆盖。什么都没有去X轴！任何想法将不胜感激。

您有两个轴所定义的相同的方式：

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轴是“类别”轴和y轴是“值”轴。尝试这个为x轴（修改）：

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

大卫，谢谢。你让我度过这个噩梦！我不得不重新排列你的建议的顺序，把它（XlAxisType.xlCategory，XlGroup.xlValue）接受，但这解决了我的问题！ – 2013-03-26 14:08:22
