IronXL 支持创建和编辑 Excel 文档中采用现代 XLSX 文件格式的图表。
此示例显示如何创建LineChart。 还支持其他图表类型。
如何在 C# 中创建 Excel 折线图
- 安装 Excel 库以创建 Excel 折线图。
- 加载 Excel 工作簿并使用
CreateChart创建图表。 - 根据需要向
Workbook添加更多值。 - 设置图表的标题和图例，并调用
Plot方法来显示图表。 - 将
Workbook数据保存到 Excel 文件中。
using IronXL;
using IronXL.Drawing.Charts;
WorkBook workBook = WorkBook.Load("test.xlsx");
WorkSheet workSheet = workBook.DefaultWorkSheet;
// Set the chart type and it's position on the worksheet.
var chart = workSheet.CreateChart(ChartType.Line, 10, 10, 18, 20);
// Add the series to the chart
// The first parameter represents the address of the range for horizontal(category) axis.
// The second parameter represents the address of the range for vertical(value) axis.
var series = chart.AddSeries("B3:B8", "A3:A8");
// Set the chart title.
series.Title = "Line Chart";
// Set the legend position.
// Can be removed by setting it to None.
chart.SetLegendPosition(LegendPosition.Bottom);
// We can change the position of the chart.
chart.Position.LeftColumnIndex = 2;
chart.Position.RightColumnIndex = chart.Position.LeftColumnIndex + 3;
// Plot all the data that was added to the chart before.
// Multiple call of this method leads to plotting multiple charts instead of modifying the existing chart.
// Yet there is no possibility to remove chart or edit it's series/position.
// We can just create new one.
chart.Plot();
workBook.SaveAs("CreateLineChart.xlsx");
