管理X和Y轴

在Excel图表中,水平和垂直轴是最常用的两种轴。

以下代码片段演示了如何设置X和Y轴的选项。

// Instantiating a Workbook object
Workbook workbook = new Workbook();
// Adding a new worksheet to the Workbook object
int sheetIndex = workbook.Worksheets.Add();
// Obtaining the reference of the newly added worksheet by passing its sheet index
Worksheet worksheet = workbook.Worksheets[sheetIndex];
// Adding sample values to cells
worksheet.Cells["A1"].PutValue("Series1");
worksheet.Cells["A2"].PutValue(50);
worksheet.Cells["A3"].PutValue(100);
worksheet.Cells["A4"].PutValue(150);
worksheet.Cells["B1"].PutValue("Series2");
worksheet.Cells["B2"].PutValue(60);
worksheet.Cells["B3"].PutValue(32);
worksheet.Cells["B4"].PutValue(50);
// Adding a chart to the worksheet
int chartIndex = worksheet.Charts.Add(Aspose.Cells.Charts.ChartType.Column, 5, 0, 15, 5);
// Accessing the instance of the newly added chart
Aspose.Cells.Charts.Chart chart = worksheet.Charts[chartIndex];
// Adding SeriesCollection (chart data source) to the chart ranging from "A1" cell to "B3"
chart.SetChartDataRange("A1:B4",true);
//hiding X axis
chart.CategoryAxis.IsVisible = false;
// Setting max value of Y axis.
chart.ValueAxis.MaxValue = 200;
// Setting major unit.
chart.ValueAxis.MajorUnit = 50;
// Save the file
workbook.Save("chart_axes.xlsx");
