How to create Excel pie of pie chart in C#, VB.NET?

Platform: WinForms |
Control: XlsIO

Syncfusion Essential XlsIO is a .NET Excel library used to create, read, and edit Excel documents. Using this library, you can create pie of pie chart in Excel.

What is a pie of pie chart?

Pie of pie chart make small slices of a pie chart easier to see. This chart type separates the smaller slices from the main pie chart and display them in a secondary pie chart.

Create Pie Of Pie Chart in Excel

Steps to create a pie of pie chart programmatically:

Step 1: Create a chart object by calling the worksheet.Charts.Add method and specify the chart type to ExcelChartType.PieOfPie enum value.

C#

//Create the chart
IChartShape chart = worksheet.Charts.Add();
 
//Set chart type to PieOfPie
chart.ChartType = ExcelChartType.PieOfPie;

 

Step 2: 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: 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 = "Pie Of 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;

 

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

  • SplitType
  • SplitValue
  • Percent (Pie Explosion)
  • GapWidth
  • PieSecondSize
  • IsVaryColor (All slices will be represented with same color if IsVaryColor is FALSE)

 

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 of pie chart.

The following C#/ VB.NET complete code snippet shows the creation of pie of 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
                IChartShape chart = worksheet.Charts.Add();
                chart.ChartType = ExcelChartType.PieOfPie;
 
                //Assign data
                chart.DataRange = worksheet["A3:B7"];
                chart.IsSeriesInRows = false;
 
                //Apply chart elements
                //Set Chart Title
                chart.ChartTitle = "Pie Of 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;
 
                //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

                Dim worksheet As IWorksheet = workbook.Worksheets(0)
 
                'Initialize chart
                Dim chart As IChartShape = worksheet.Charts.Add()
                chart.ChartType = ExcelChartType.PieOfPie
 
                'Assign data

                serie.DataPoints.DefaultDataPoint.DataLabels.Position = ExcelDataLabelPosition.BestFit
 
                'Positioning chart in the worksheet
                chart.TopRow = 8
                chart.LeftColumn = 1
                chart.BottomRow = 23
                chart.RightColumn = 8
 
                'Saving and closing the workbook
