# How to show the leader line on Excel chart using XlsIO?
2+
3+
Step 1: Create a New C# Console Application Project.
4+
5+
Step 2: Name the Project.
6+
7+
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).
8+
9+
Step 4: Include the following namespaces in the **Program.cs** file.
10+
11+
```csharp
12+
using System;
13+
using System.IO;
14+
using Syncfusion.XlsIO;
15+
```
16+
17+
Step 5: Include the below code snippet in **Program.cs** to show the leader line on Excel chart.
18+
19+
```csharp
20+
using (ExcelEngine excelEngine = new ExcelEngine())
21+
{
22+
IApplication application = excelEngine.Excel;
23+
application.DefaultVersion = ExcelVersion.Xlsx;
24+
IWorkbook workbook = application.Workbooks.Create(1);
25+
IWorksheet sheet = workbook.Worksheets[0];
26+
27+
//Add data
28+
sheet.Range["A1"].Text = "Fruit";
29+
sheet.Range["B1"].Text = "Quantity";
30+
sheet.Range["A2"].Text = "Apple";
31+
sheet.Range["A3"].Text = "Banana";
32+
sheet.Range["A4"].Text = "Cherry";
33+
sheet.Range["B2"].Number = 40;
34+
sheet.Range["B3"].Number = 30;
35+
sheet.Range["B4"].Number = 30;
36+
37+
//Add a Pie chart
38+
IChart chart = sheet.Charts.Add();
39+
chart.ChartType = ExcelChartType.Pie;
40+
chart.DataRange = sheet.Range["A1:B4"];
41+
chart.IsSeriesInRows = false;
42+
chart.ChartTitle = "Fruit Distribution";
43+
44+
//Enable data labels with values, and leader lines
45+
IChartSerie series = chart.Series[0];
46+
series.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
47+
series.DataPoints.DefaultDataPoint.DataLabels.ShowLeaderLines = true;
48+
49+
//Manually resizing data label area using Manual Layout
50+
chart.Series[0].DataPoints[0].DataLabels.Layout.ManualLayout.Left = 0.09;
51+
chart.Series[0].DataPoints[0].DataLabels.Layout.ManualLayout.Top = 0.01;
52+
53+
#region Save
54+
//Saving the workbook
55+
FileStream outputStream = new FileStream(Path.GetFullPath("Output.xlsx"), FileMode.Create, FileAccess.Write);
56+
workbook.SaveAs(outputStream);
57+
#endregion
58+
59+
//Dispose streams
60+
outputStream.Dispose();
61+
}
62+
```
