How to create Excel stacked bar cone chart in C#, VB.NET?
This article explains how to create Stacked Bar Cone Chart in Excel using Syncfusion Excel (XlsIO) library.
What is Stacked Bar Cone Chart?
A variation on a column/bar chart that uses cone shapes instead of rectangular columns/bars is called a Cone chart. In a stacked bar cone chart, each series is horizontally stacked one after the other.
Stacked Bar Cone Chart
To create stacked bar cone chart in Excel using XlsIO, you need to do the following steps.
Steps to create Stacked Bar Cone Chart:
Step 1: Initialize chart
Create a chart object by calling the worksheet.Charts.Add method and specify the chart type to ExcelChartType.Cone_Bar_Stacked enumeration value.
C#
//Create the chart
IChartShape chart = worksheet.Charts.Add();
//Set chart type to Cone_Bar_Stacked
chart.ChartType = ExcelChartType.Cone_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.
C#
//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.
C#
//Set chart title
chart.ChartTitle = "Stacked Bar Cone 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.
C#
//Set rotation and elevation
chart.Rotation = 20;
chart.Elevation = 20;
Applicable properties for Stacked Bar Cone Chart
Below is the list of other common properties applicable for stacked bar cone 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 cone chart.

The following C#/ VB.NET complete code snippet shows the creation of stacked bar cone 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.Cone_Bar_Stacked;
//Assign data
chart.DataRange = worksheet["A1:D6"];
chart.IsSeriesInRows = false;
//Apply chart elements
//Set chart title
chart.ChartTitle = "Stacked Bar Cone Chart";
//Set legend
chart.HasLegend = true;
chart.Legend.Position = ExcelLegendPosition.Bottom;
//Set rotation and elevation
chart.Rotation = 20;
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);
}
}
}
}
