在Excel中使用C#进行互操作创建漏斗图的步骤如下:
using Excel = Microsoft.Office.Interop.Excel;
Excel.Application excelApp = new Excel.Application();
Excel.Workbook workbook = excelApp.Workbooks.Add();
Excel.Worksheet worksheet = workbook.ActiveSheet;
string[] categories = { "Category 1", "Category 2", "Category 3" };
int[] values = { 100, 75, 50 };
Excel.ChartObjects chartObjects = worksheet.ChartObjects();
Excel.ChartObject chartObject = chartObjects.Add(100, 100, 300, 300);
Excel.Chart chart = chartObject.Chart;
chart.ChartType = Excel.XlChartType.xlFunnel;
Excel.Range dataRange = worksheet.Range["A1:B4"];
dataRange.Value = new object[,] { { "Category", "Value" }, { categories[0], values[0] }, { categories[1], values[1] }, { categories[2], values[2] } };
chart.SetSourceData(dataRange);
workbook.SaveAs("path/to/save/excel.xlsx");
workbook.Close();
excelApp.Quit();
通过以上步骤,你可以使用C#在Excel中创建一个漏斗图。请注意,以上代码仅为示例,实际应用中可能需要根据具体需求进行适当的修改。
