Create Pie Chart in Excel

8 Dec 20238 minutes to read

The pie charts are used to display the contribution of each value (slice) to a total (pie). So, it is easy to compare proportions. Pie charts always use one data series.

The following code shows how to create pie chart in Excel and to place it in a worksheet with Interop and XlsIO for .NET.

Interop

C#

private void CreatePieChart()
{
  //Instantiate the application object
  var excelApp = new Microsoft.Office.Interop.Excel.Application();

  //Add a workbook
  Workbook workbook = excelApp.Workbooks.Add(System.Reflection.Missing.Value);

  //Get the first sheet
  Worksheet sheet = workbook.Sheets["Sheet1"];

  //Add sample data for pie chart
  //Add headings in A1 and B1.
  sheet.Cells[1, 1] = "Products";
  sheet.Cells[1, 2] = "Users";

  //Add data from A2 till B4
  sheet.Cells[2, 1] = "XlsIO";
  sheet.Cells[2, 2] = 10000;
  sheet.Cells[3, 1] = "DocIO";
  sheet.Cells[3, 2] = 8000;
  sheet.Cells[4, 1] = "PDF";
  sheet.Cells[4, 2] = 12000;

  //Add a pie chart
  ChartObjects charts = (ChartObjects)sheet.ChartObjects(Type.Missing);
  ChartObject chartObject = (ChartObject)charts.Add(10, 80, 300, 250);
  Chart chart = chartObject.Chart;
  chart.ChartType = XlChartType.xlPie;

  //Set chart title
  chart.HasTitle = true;
  chart.ChartTitle.Text = "Users";

  //Gets the cells that define the data to be charted
  Range chartRange = sheet.get_Range("A2", "B4");
  chart.SetSourceData(chartRange, Type.Missing);

  //Save the Excel file
  workbook.SaveCopyAs("InteropOutput_PieChart.xlsx");

  //Quit the application
  excelApp.Quit();

}

VB.NET

Private Sub CreatePieChart()
  'Instantiate the application object
  Dim excelApp = New Microsoft.Office.Interop.Excel.Application()

  'Add a workbook
  Dim workbook As Workbook = excelApp.Workbooks.Add(System.Reflection.Missing.Value)

  'Get the first sheet
  Dim sheet As Worksheet = workbook.Sheets("Sheet1")

  'Add sample data for pie chart
  'Add headings in A1 and B1.
  sheet.Cells(1, 1) = "Products"
  sheet.Cells(1, 2) = "Users"

  'Add data from A2 till B4
  sheet.Cells(2, 1) = "XlsIO"
  sheet.Cells(2, 2) = 10000
  sheet.Cells(3, 1) = "DocIO"
  sheet.Cells(3, 2) = 8000
  sheet.Cells(4, 1) = "PDF"
  sheet.Cells(4, 2) = 12000

  'Add a pie chart
  Dim charts As ChartObjects = CType(sheet.ChartObjects(Type.Missing), ChartObjects)
  Dim chartObject As ChartObject = CType(charts.Add(10, 80, 300, 250), ChartObject)
  Dim chart As Chart = chartObject.Chart
  chart.ChartType = XlChartType.xlPie

  'Set chart title
  chart.HasTitle = True
  chart.ChartTitle.Text = "Users"

  'Gets the cells that define the data to be charted
  Dim chartRange As Range = sheet.Range("A2", "B4")
  chart.SetSourceData(chartRange, Type.Missing)

  'Save the file
  workbook.SaveCopyAs("InteropOutput_PieChart.xlsx")

  'Quit the application
  excelApp.Quit()
End Sub
