How to create Excel stacked bar pyramid chart in C#, VB.NET?

3 mins read

This article explains how to create Stacked Bar Pyramid Chart in Excel using Syncfusion Excel (XlsIO) library.

What is a Stacked Bar Pyramid Chart?

A variation on a column/bar chart that uses pyramid shapes instead of rectangular columns/bars is called a Pyramid chart. In a stacked bar pyramid chart, each series is horizontally stacked one after the other.

Create Stacked Bar Pyramid Chart in Excel

Stacked Bar Pyramid Chart

To create stacked bar pyramid chart in Excel using XlsIO, you need to do the following steps.

Steps to create Stacked Bar 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_Bar_Stacked enumeration value.

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

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 = "Stacked Bar 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 chart object.

//Set rotation and elevation
chart.Rotation = 50;
chart.Elevation = 20;

Applicable properties for Stacked Bar Pyramid Chart

Below is the list of other common properties applicable for stacked bar pyramid chart.

GapWidth
GapDepth
BarShapeBase & BarShapeTop (to change the shape of column/bar)
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 stacked bar pyramid chart.

                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;
