如何在xlLine ChartType中使用Y轴的string值

我需要使用excel.interop生成一些折线图，我想为Y轴值设置文本。

Dictionary<string, int> data = new Dictionary<string, int>(); data.Add("abc", 1); data.Add("def", 2); data.Add("ghi", 3); data.Add("jkl", 4); data.Add("mno", 5); var application = new excel.Application(); var workbook = application.Workbooks.Open(docName); var worksheet = workbook.Worksheets[1] as excel.Worksheet; var charts = worksheet.ChartObjects() as excel.ChartObjects; var chartObject = charts.Add(60, 10, 300, 300); var chart = chartObject.Chart; chart.ChartType = excel.XlChartType.xlLine; chart.Location(excel.XlChartLocation.xlLocationAsObject, worksheetName); var seriesCollection = (excel.SeriesCollection)chart.SeriesCollection(); var series = seriesCollection.NewSeries(); series.Values = data.Keys.ToArray(); series.XValues = data.Values.ToArray(); series.Name = "test"; workbook.Save(); 

但这是我的结果（series.Values只包含0个值）。

Answer 1

也许你想为X轴使用文本？

  //series.Values = data.Keys.ToArray(); //series.XValues = data.Values.ToArray(); series.XValues = data.Keys.ToArray(); series.Values = data.Values.ToArray(); 

或者也许你可以使用条形图：
