This article explains how to create an Exploded Pie Chart in Excel using Syncfusion Excel (XlsIO) library. What is an Exploded Pie Chart?A simple pie chart with pie explosion can be considered as an exploded pie chart. You can change the pie explosion setting for either all slices or individual slice.
Exploded Pie Chart To create an exploded pie chart in Excel using XlsIO, you need to do the following steps. Steps to create Exploded Pie Chart:Step 1: Initialize chartCreate a chart object by calling the worksheet.Charts.Add method and specify the chart type to ExcelChartType.Pie_Exploded enumeration value. C# //Create the chart IChartShape chart = worksheet.Charts.Add(); //Set chart type to Pie_Exploded chart.ChartType = ExcelChartType.Pie_Exploded;
Step 2: Assign dataSet 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 elementsAdd the basic elements like chart title, data labels and legend with below list of properties.
C# //Set chart title chart.ChartTitle = "Exploded Pie Chart"; //Set data labels IChartSerie serie1 = chart.Series[0]; serie1.DataPoints.DefaultDataPoint.DataLabels.IsValue = true; //Set legend chart.HasLegend = true; chart.Legend.Position = ExcelLegendPosition.Bottom;
Applicable properties for Exploded Pie ChartBelow is the list of other common properties applicable for exploded pie chart.
Note:
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 exploded 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.Pie_Exploded;
//Assign data
chart.DataRange = worksheet["A3:B7"];
chart.IsSeriesInRows = false;
//Apply chart elements
//Set chart title
chart.ChartTitle = "Exploded Pie Chart";
//Set legend
chart.HasLegend = true;
chart.Legend.Position = ExcelLegendPosition.Bottom;
//Set data labels
IChartSerie serie1 = chart.Series[0];
serie1.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
//Positioning the chart in the worksheet
chart.TopRow = 8;
chart.LeftColumn = 1;
chart.BottomRow = 23;
chart.RightColumn = 8;
//Saving the workbook
Stream stream = File.Create("Output.xlsx");
workbook.SaveAs(stream);
}
}
}
}
