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

3 mins read

This article explains how to create 3D Clustered Pyramid Chart in Excel using Syncfusion Excel (XlsIO) library.

What is 3D Clustered Pyramid Chart?

A variation on a column/bar chart that uses pyramid shapes instead of rectangular columns/bars is called a Pyramid chart. A 3D clustered pyramid chart uses three axes (horizontal axis, vertical axis and depth axis), and they compare data points along the horizontal and the depth axes. This chart can be used to compare data across both the categories and the data series.

3D Clustered Pyramid Chart

To create 3D clustered pyramid chart in Excel using XlsIO, you need to do the following steps.

Steps to create 3D Clustered Pyramid Chart:

Step 1: Initialize chart

Create a chart object by calling the worksheet.Charts.Add method and specify the chart type to ExcelChartType.Pyramid_Clustered_3D enumeration value.

//Create the chart
IChartShape chart = worksheet.Charts.Add();
//Set chart type to Pyramid_Clustered_3D
chart.ChartType = ExcelChartType.Pyramid_Clustered_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["A1:D6"];
//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 below list of properties.

ChartTitle of chart object.
Set DataLabels via DefaultDataPoint.
Set TRUE to chart’s HasLegend property, to show the legend.

//Set chart title
chart.ChartTitle = "3D 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, elevation and perspective.

Rotation, Elevation and Perspective of chart object.

//Set rotation, elevation and perspective
chart.Rotation = 15;
chart.Elevation = 10; 
chart.Perspective = 0;

Applicable properties for 3D Clustered Pyramid Chart

Below is the list of other common properties applicable for 3D clustered pyramid chart.

GapWidth
GapDepth
BarShapeBase & BarShapeTop (to change the shape of column/bar)
PrimarySerieAxis (Depth Axis)

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 3D clustered pyramid chart.
