【问题描述】：
我已经完成了 99% 的创建文件以执行外部程序，然后获取数据并运行计算并将其放入 Excel 电子表格中。
最后一部分是从程序中创建一个 XY 散点图。我在注释行//添加图表处开始图表，但将其前面的内容包括在内作为参考

Excel.Range chartRange;
/*
Excel.ChartObjects xlCharts = (Excel.ChartObjects)Sheet.ChartObjects(Type.Missing);
Excel.ChartObject myChart = (Excel.ChartObject)xlCharts.Add(180, 30, 300, 250); //location chart pops up
Excel.Chart chartPage = myChart.Chart;
*/
// Add chart.
var charts = Sheet.ChartObjects() as
Microsoft.Office.Interop.Excel.ChartObjects;
var chartObject = charts.Add(180, 30, 300, 300) as
Microsoft.Office.Interop.Excel.ChartObject;
var chart = chartObject.Chart;
// Set chart range.
chartRange = Sheet.get_Range("A2","B11");
chart.SetSourceData(chartRange);
// Set chart properties.
chart.ChartType = Excel.XlChartType.xlXYScatterLines;
chart.ChartWizard(Source: "A2:B11",
Title: "graphTitle",
CategoryTitle: "xAxis",
ValueTitle: "yAxis");
Book.SaveAs(fileTest);
Book.Close();
App.Quit();
System.Diagnostics.Process.Start(@"C:\\Cinder\\" + titleTextBox.Text + "\\table.xlsx");
这是我试图绘制的数据示例：
Minutes after run mRem/hr @ 1 ft
20 61.69948
30 53.60822
40 51.91109
50 51.18693
60 50.77799
120 49.51441
180 48.61834
240 47.83341
360 46.38796
它将 X 轴绘制为 Y 轴上的值，而不是根据我提供的数据制作 X 轴。
如何让散点图正确生成 X 轴值？当我在 excel 中选择数据范围并制作散点图时，它看起来完全没有问题。
谢谢！
