如何在 Aspose 图的 x 轴上显示自定义标签？

Question

我有一个 aspose Column3DClustered graph.Currently x 轴显示数字值，只说 1,2...我想显示一些标签，如 "Apple"、"Orange"等等..而不是 1,2etc..我怎样才能使用 aspose 实现这个？

Workbook workbook = new Workbook();
Worksheet worksheet = workbook.Worksheets[0];

worksheet.Cells[0, 0].PutValue(1);
worksheet.Cells[0, 1].PutValue(50);
worksheet.Cells[0, 2].PutValue(100);

worksheet.Cells[1, 0].PutValue(2);
worksheet.Cells[1, 1].PutValue(50);
worksheet.Cells[1, 2].PutValue(20);


int chartIndex = worksheet.Charts.Add(ChartType.Column3DClustered, 5, 0, 15, 5);
Chart chart = worksheet.Charts[chartIndex];
chart.Title.Text = "Fruits for period 6/2016";

chart.Title.Font.Size = 6;
chart.NSeries.Add("B1:B2", true);
chart.NSeries.Add("C1:C2", true);

chart.NSeries[0].Name = "Total Quantity";
chart.NSeries[1].Name = "Net Available";
chart.NSeries[0].DataLabels.ShowValue = true;
chart.NSeries[0].DataLabels.Font.Size = 6;
chart.NSeries[0].Area.ForegroundColor = Color.DeepSkyBlue;
chart.NSeries[1].DataLabels.ShowValue = true;
chart.NSeries[1].DataLabels.Font.Size = 6;
chart.NSeries[1].Area.ForegroundColor = Color.MediumPurple;
chart.Legend.Position = LegendPositionType.Bottom;
chart.Legend.Font.Size = 6;

Answer 1

请根据您的需要使用Chart.NSeries.CategoryData。请参阅以下示例代码。它加载示例 Excel 文件并更改 类别数据，即图表的 X 轴 并将其保存为输出 Excel 文件。

C#

//Load the sample Excel file.
Workbook wb = new Workbook("Sample.xlsx");

//Access first worksheet.
Worksheet ws = wb.Worksheets[0];

//Access first chart.
Chart ch = ws.Charts[0];

//Change the category data - X axis values.
ch.NSeries.CategoryData = "=Sheet1!$C:$C";

//Save the output Excel file.
wb.Save("Output.xlsx");

请看这张图片。它显示了示例 Excel 文件、输出 Excel 文件以及代码对它们的影响，供您参考。
