How to create Excel clustered pyramid chart in C#, VB.NET?
This article explains how to create a Clustered Pyramid Chart in Excel using the Syncfusion Excel (XlsIO) library.
What is a Clustered Pyramid Chart?
A variation of a column/bar chart that uses pyramid shapes instead of rectangular columns/bars is called a Pyramid Chart. A clustered pyramid chart plots the data in discrete vertical pyramids.
Clustered Pyramid Chart
To create a clustered pyramid chart in Excel using XlsIO, you need to do the following steps.
Steps to create a Clustered Pyramid Chart:
Step 1: Initialize the chart
Create a chart object by calling the worksheet.Charts.Add method and specify the chart type as the ExcelChartType.Pyramid_Clustered enumeration value.
C#
// Create the chart IChartShape chart = worksheet.Charts.Add(); // Set chart type to Pyramid_Clustered chart.ChartType = ExcelChartType.Pyramid_Clustered;
Step 2: Assign data
Set a range of data from the worksheet to the chart’s DataRange property. To plot the series values in columns and categories in rows, set the chart’s IsSeriesInRows property to false.
C#
// Set region of chart data chart.DataRange = worksheet["A1:D6"]; // Set chart series in columns for the assigned data region chart.IsSeriesInRows = false;
Step 3: Apply basic chart elements
Add the basic elements like the chart title, data labels, and legend using the properties listed below:
- ChartTitle of the chart object.
- Set DataLabels via DefaultDataPoint.
- Set TRUE to the chart’s HasLegend property, to show the legend.
C#
// Set chart title chart.ChartTitle = "Clustered Pyramid 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;
Step 4: Apply 3D chart elements
Add the 3D chart elements like rotation and elevation.
- Rotation and Elevation of the chart object.
C#
// Set rotation and elevation chart.Rotation = 50; chart.Elevation = 20;
Applicable properties for Clustered Pyramid Chart
Below is the list of other common properties applicable for a clustered pyramid chart.
- GapWidth
- GapDepth
- BarShapeBase & BarShapeTop (to change the shape of columns/bars)Note:
Applying properties apart from the mentioned list might throw an exception or the changes will not be reflected in the output document because those properties are not related to clustered pyramid chart.

The following C#/VB.NET complete code snippet shows the creation of a Clustered Pyramid 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.Pyramid_Clustered;
// Assign data
chart.DataRange = worksheet["A1:D6"];
chart.IsSeriesInRows = false;
// Apply chart elements
// Set chart title
chart.ChartTitle = "Clustered Pyramid Chart";
// Set legend
chart.HasLegend = true;
chart.Legend.Position = ExcelLegendPosition.Bottom;
// Set rotation and elevation
chart.Rotation = 50;
chart.Elevation = 20;
// Set data labels
IChartSerie serie1 = chart.Series[0];
IChartSerie serie2 = chart.Series[1];
IChartSerie serie3 = chart.Series[2];
serie1.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
serie2.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
serie3.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);
}
}
}
}
