How to create Excel 3D pie chart in C#, VB.NET?

3 mins read

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.

            //Create the chart
            IChartShape chart = worksheet.Charts.Add();
 
            //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.

            //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.

              //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

Add 3D chart element Elevation.

Elevation of chart object.

              //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.

Percent (Pie Explosion)
First Slice Angle
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.

            {
                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.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);
            }
        }
    }
}
