在Excel图表更改轴标签在C＃创建(Changing Axis Labels on Excel C

所以，我一直在努力，现在摸不着头脑了一段时间，但似乎无法取得任何进展。我创建一个使用C＃的Excel电子表格。我的电子表格包含图表。我能够做的一切与图表唯有变化是X轴的标签。我已经尝试过，我可以找到，但没有工作的一切。

Excel.ChartObjects xlChart = (Excel.ChartObjects)xlWorkSheet.ChartObjects(Type.Missing);
Excel.ChartObject myChart = (Excel.ChartObject)xlChart.Add(1420, 660, 320, 180);
Excel.Chart chartPage = myChart.Chart;
chartPage.ChartType = Excel.XlChartType.xlXYScatterLines;
chartPage.HasTitle = true;
chartPage.ChartTitle.Text = "Title Text";
chartPage.HasLegend = false;

var yAxis = (Excel.Axis)chartPage.Axes(Excel.XlAxisType.xlValue,Excel.XlAxisGroup.xlPrimary);
yAxis.HasTitle = true;
yAxis.AxisTitle.Text = "Y-Axis Title text";
yAxis.MaximumScale = 20;
yAxis.AxisTitle.Orientation = Excel.XlOrientation.xlUpward;

Excel.Range Data_Range = xlWorkSheet.get_Range("A10", "C10");//Data to be plotted in chart
Excel.Range XVal_Range = xlWorkSheet.get_Range("A1", "C1");//Catagory Names I want on X-Axis as range
var x_labels = new List<string>() { "Val1", "Val2", "Val3" }; //Catagory Names I want on X-Axis as text array

Excel.SeriesCollection oSeriesCollection = (Excel.SeriesCollection)myChart.Chart.SeriesCollection(misValue);
Excel.Series Data = oSeriesCollection.NewSeries();
Data.Values = Data_Range;
Data.Name = "Plot Data";

Excel.Axis valueAxis = (Excel.Axis)chartPage.Axes(Excel.XlAxisType.xlCategory, Excel.XlAxisGroup.xlPrimary);
/*
Methods I've tried with no luck:
1) Data.XValues = XVal_Range;
2) Data.XValues = x_labels.ToArray();
3) valueAxis.CategoryNames = x_labels.ToArray();
4) valueAxis.CategoryNames = XVal_Range;
*/

每次它只是使用默认的数值显示的时间......我不知所措

好了，所以我想通了这个问题...你不能改变X轴的散点图类型图表。我改变图形以类型Excel.XlChartType.xlLineMarkers; 它工作得很好。

这里就是整个片段：

Excel.ChartObjects xlChart = (Excel.ChartObjects)xlWorkSheet.ChartObjects(Type.Missing);
Excel.ChartObject myChart = (Excel.ChartObject)xlChart.Add(1420, 660, 320, 180);
Excel.Chart chartPage = myChart.Chart;
chartPage.ChartType = Excel.XlChartType.xlLineMarkers;
chartPage.HasTitle = true;
chartPage.ChartTitle.Text = "Title Text";
chartPage.HasLegend = false;

var yAxis = (Excel.Axis)chartPage.Axes(Excel.XlAxisType.xlValue,Excel.XlAxisGroup.xlPrimary);
yAxis.HasTitle = true;
yAxis.AxisTitle.Text = "Y-Axis Title text";
yAxis.MaximumScale = 20;
yAxis.AxisTitle.Orientation = Excel.XlOrientation.xlUpward;

Excel.Range Data_Range = xlWorkSheet.get_Range("A10", "C10");//Data to be plotted in chart
Excel.Range XVal_Range = xlWorkSheet.get_Range("A1", "C1");//Catagory Names I want on X-Axis as range

Excel.SeriesCollection oSeriesCollection = (Excel.SeriesCollection)myChart.Chart.SeriesCollection(misValue);
Excel.Series Data = oSeriesCollection.NewSeries();
Data.Values = Data_Range;
Data.Name = "Plot Data";

Excel.Axis xAxis = (Excel.Axis)chartPage.Axes(Excel.XlAxisType.xlCategory, Excel.XlAxisGroup.xlPrimary);
xAxis.CategoryNames = XVal_Range;
