+# How to show the leader line on Excel chart using XlsIO?
+
+Step 1: Create a New C# Console Application Project.
+
+Step 2: Name the Project.
+
+Step 3: Install the [Syncfusion.XlsIO.Net.Core](https://www.nuget.org/packages/Syncfusion.XlsIO.Net.Core) NuGet package as reference to your .NET Standard applications from [NuGet.org](https://www.nuget.org).
+
+Step 4: Include the following namespaces in the **Program.cs** file.
+
+```csharp
+using System;
+using System.IO;
+using Syncfusion.XlsIO;
+```
+
+Step 5: Include the below code snippet in **Program.cs** to show the leader line on Excel chart.
+
+```csharp
+using (ExcelEngine excelEngine = new ExcelEngine())
+{
+ IApplication application = excelEngine.Excel;
+ application.DefaultVersion = ExcelVersion.Xlsx;
+ IWorkbook workbook = application.Workbooks.Create(1);
+ IWorksheet sheet = workbook.Worksheets[0];
+
+ //Add data
+ sheet.Range["A1"].Text = "Fruit";
+ sheet.Range["B1"].Text = "Quantity";
+ sheet.Range["A2"].Text = "Apple";
+ sheet.Range["A3"].Text = "Banana";
+ sheet.Range["A4"].Text = "Cherry";
+ sheet.Range["B2"].Number = 40;
+ sheet.Range["B3"].Number = 30;
+ sheet.Range["B4"].Number = 30;
+
+ //Add a Pie chart
+ IChart chart = sheet.Charts.Add();
+ chart.ChartType = ExcelChartType.Pie;
+ chart.DataRange = sheet.Range["A1:B4"];
+ chart.IsSeriesInRows = false;
+ chart.ChartTitle = "Fruit Distribution";
+
+ //Enable data labels with values, and leader lines
+ IChartSerie series = chart.Series[0];
+ series.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
+ series.DataPoints.DefaultDataPoint.DataLabels.ShowLeaderLines = true;
+
+ //Manually resizing data label area using Manual Layout
+ chart.Series[0].DataPoints[0].DataLabels.Layout.ManualLayout.Left = 0.09;
+ chart.Series[0].DataPoints[0].DataLabels.Layout.ManualLayout.Top = 0.01;
+
+ #region Save
+ //Saving the workbook
+ FileStream outputStream = new FileStream(Path.GetFullPath("Output.xlsx"), FileMode.Create, FileAccess.Write);
+ workbook.SaveAs(outputStream);
