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

What is a sunburst chart?

Sunburst provides a hierarchical view of data where each level of the hierarchy is represented by one ring or circle with the innermost circle as the top of the hierarchy.

Create Sunburst Chart in Excel

Sunburst Chart

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

Steps to create sunburst chart:

Step 1: Initialize chart

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

C#

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

 

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["A1:D16"];
 
            //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 with the below list of properties.

  • 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 = "Sunburst Chart";
 
              //Set Legend
              chart.HasLegend = false;
              
              //Set Datalabels
              IChartSerie serie1 = chart.Series[0];
              serie1.DataPoints.DefaultDataPoint.DataLabels.IsCategoryName = true; 
 

 

Applicable properties of sunburst chart

Note:

 

  1. Applying other properties unrelated to this chart might throw exception or the changes will not be reflected in the output document because those properties are not related to sunburst chart.
  2. As sunburst chart is introduced in MS Excel 2016, it can’t be viewed in MS Excel 2013 and its earlier versions.

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.SunBurst;
 
                //Assign data
                chart.DataRange = worksheet["A1:D16"];
                chart.IsSeriesInRows = false;
 
                //Apply chart elements
                //Set Chart Title
                chart.ChartTitle = "Sunburst Chart";
 
                //Set Datalabels
                IChartSerie serie1 = chart.Series[0];
                serie1.DataPoints.DefaultDataPoint.DataLabels.IsCategoryName = true;
 
                //Set Legend
                chart.HasLegend = false;
 
                //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);
            }
        }
    }
}
