This article explains how to create a 3D pie chart in Excel using Syncfusion Excel (XlsIO) library.

## What is 3D pie chart?

A pie chart (or a circle chart) is a circular statistical graphic which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice is proportional to the quantity it represents.

3D Pie Chart

To create a 3D pie chart in Excel using XlsIO, you need to do the following steps.

## Steps to create 3D pie chart

### Step 1: Initialize chart

Create a chart object by calling the worksheet.Charts.Add method and specify the chart type to ExcelChartType.Pie_3D enum value.

C#

```            //Create the chart

//Set chart type to Pie_3D
chart.ChartType = ExcelChartType.Pie_3D;
```

### Step 2: Assign data

Set a range of data from the worksheet to chart’s DataRange property. To plot the series values in column and categories in row, set chart’s IsSeriesInRows property to false.

C#

```            //Set region of Chart data
chart.DataRange = worksheet["A3:B7"];

//Set chart series in column for assigned data region
chart.IsSeriesInRows = false;
```

### Step 3: Apply basic chart elements

Add the basic elements like chart title, data labels and legend.

• ChartTitle of chart object.
• Set DataLabels via DefaultDataPoint.
• Set TRUE to chart’s HasLegend property, to show the legend.

C#

```              //Apply chart elements
//Set Chart Title
chart.ChartTitle = "3D Pie Chart";

//Set Legend
chart.HasLegend = true;
chart.Legend.Position = ExcelLegendPosition.Bottom;

//Set Datalabels
IChartSerie serie = chart.Series[0];
serie.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
serie.DataPoints.DefaultDataPoint.DataLabels.Position = ExcelDataLabelPosition.BestFit;

```

### Step 4: Apply 3D chart elements

• Elevation of chart object.

C#

```              //Set Elevation
chart.Elevation = 30;

```

## Applicable properties of 3D pie chart

Below is the list of other properties that is applicable for a pie chart.

1. Percent (Pie Explosion)
2. First Slice Angle
3. IsVaryColor (All slices will be represented with same color if IsVaryColor is FALSE)
Note:

Applying properties apart from the mentioned list might throw exception or the changes will not be reflected in the output document because those properties are not related to pie chart.

To know more about creating charts with various settings using Syncfusion Excel (XlsIO) library, please refer the documentation.

The following C#/ VB.NET complete code snippet shows the creation of 3D pie chart using XlsIO.

C#

```using Syncfusion.XlsIO;
using System.Reflection;
using System.IO;

namespace ChartSample
{
class Program
{
static void Main(string[] args)
{
using (ExcelEngine excelEngine = new ExcelEngine())
{
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Excel2016;

//Open existing workbook with data entered
Assembly assembly = typeof(Program).GetTypeInfo().Assembly;
Stream fileStream = assembly.GetManifestResourceStream("ChartSample.InputTemplate.xlsx");
IWorkbook workbook = application.Workbooks.Open(fileStream);
IWorksheet worksheet = workbook.Worksheets[0];

//Initialize chart
chart.ChartType = ExcelChartType.Pie_3D;

//Assign data
chart.DataRange = worksheet["A3:B7"];
chart.IsSeriesInRows = false;

//Apply chart elements
//Set Chart Title
chart.ChartTitle = "3D Pie Chart";

//Set Legend
chart.HasLegend = true;
chart.Legend.Position = ExcelLegendPosition.Bottom;

//Set Datalabels
IChartSerie serie = chart.Series[0];
serie.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
serie.DataPoints.DefaultDataPoint.DataLabels.Position = ExcelDataLabelPosition.BestFit;

//Set Elevation
chart.Elevation = 30;

//Positioning the chart in the worksheet
chart.TopRow = 8;
chart.LeftColumn = 1;
chart.BottomRow = 23;
chart.RightColumn = 8;

//Saving and closing the workbook
Stream stream = File.Create("Output.xlsx");
workbook.SaveAs(stream);
}
}
}
}
```

VB.NET

```Imports Syncfusion.XlsIO
Imports System.Reflection
Imports System.IO

Namespace ChartSample

Class Program

Public Shared Sub Main(ByVal args As String())
Using excelEngine As ExcelEngine = New ExcelEngine()
Dim application As IApplication = excelEngine.Excel
application.DefaultVersion = ExcelVersion.Excel2016

'Open existing workbook with data entered
Dim assembly As Assembly = GetType(Program).GetTypeInfo().Assembly
Dim fileStream As Stream = assembly.GetManifestResourceStream("ChartSample.InputTemplate.xlsx")
Dim workbook As IWorkbook = application.Workbooks.Open(fileStream)
Dim worksheet As IWorksheet = workbook.Worksheets(0)

'Initialize chart
Dim chart As IChartShape = worksheet.Charts.Add()
chart.ChartType = ExcelChartType.Pie_3D

'Assign data
chart.DataRange = worksheet("A3:B7")
chart.IsSeriesInRows = False

'Apply chart elements
'Set Chart Title
chart.ChartTitle = "3D Pie Chart"

'Set Legend
chart.HasLegend = True
chart.Legend.Position = ExcelLegendPosition.Bottom

'Set Datalabels
IChartSerie serie = chart.Series[0]
serie.DataPoints.DefaultDataPoint.DataLabels.IsValue = True
serie.DataPoints.DefaultDataPoint.DataLabels.Position = ExcelDataLabelPosition.BestFit

'Set Elevation
chart.Elevation = 30;

'Positioning chart in the worksheet
chart.TopRow = 8
chart.LeftColumn = 1
chart.BottomRow = 23
chart.RightColumn = 8

'Saving and closing the workbook
Dim stream As Stream = File.Create("Output.xlsx")
workbook.SaveAs(stream)
End Using
End Sub
End Class
End Namespace
```
