This article explains how to create a 3D bubble chart in Excel using Syncfusion Excel (XlsIO) library. What is a 3D bubble chart?A 3D bubble chart represents data points with bubbles along with an additional dimension of the data, the size of bubbles.
3D Bubble Chart To create a 3D bubble chart in Excel using XlsIO, you need to do the following steps. Steps to create 3D bubble chart:Step 1: Initialize chartCreate a chart object by calling the worksheet.Charts.Add method and specify the chart type to ExcelChartType.Bubble_3D enum value. C# //Create the chart IChartShape chart = worksheet.Charts.Add(); //Set chart type to Bubble_3D chart.ChartType = ExcelChartType.Bubble_3D;
Step 2: Assign data and chart elementsAdd the basic elements like chart title, data labels and legend.
C# //Apply chart elements //Set Chart Title chart.ChartTitle = "3D Bubble Chart"; //Set Legend chart.HasLegend = false; //Set Datalabels, CategoryLabels and Values IChartSerie serie = chart.Series.Add(); serie.CategoryLabels = worksheet.Range["A2:A11"]; serie.Values = worksheet.Range["B2:B11"]; serie.Bubbles = worksheet.Range["C2:C11"]; serie.DataPoints.DefaultDataPoint.DataLabels.IsValue = true; serie.DataPoints.DefaultDataPoint.DataLabels.Position = ExcelDataLabelPosition.Center;
Applicable properties of 3D bubble chartBelow is the list of other properties that is applicable for a bubble chart.
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 3D bubble 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.input.xlsx");
IWorkbook workbook = application.Workbooks.Open(fileStream);
IWorksheet worksheet = workbook.Worksheets[0];
//Initialize chart
IChartShape chart = worksheet.Charts.Add();
chart.ChartType = ExcelChartType.Bubble_3D;
//Apply chart elements
//Set Chart Title
chart.ChartTitle = "3D Bubble Chart";
//Set Legend
chart.HasLegend = false;
//Set Datalabels, CategoryLabels and Values
IChartSerie serie = chart.Series.Add();
serie.CategoryLabels = worksheet.Range["A2:A11"];
serie.Values = worksheet.Range["B2:B11"];
serie.Bubbles = worksheet.Range["C2:C11"];
serie.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
serie.DataPoints.DefaultDataPoint.DataLabels.Position = ExcelDataLabelPosition.Center;
//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);
}
}
}
}
