How to create Excel stacked column chart in C#, VB.NET?
This article explains how to create a stacked column chart in Excel using Syncfusion Excel (XlsIO) library.
What is a Stacked column chart?
In Stacked column chart, each series is vertically stacked one above the other. When there is only one series, then it will have similar appearance to clustered column chart.
To create a stacked column chart using XlsIO, you will need to do the following steps.
Stacked Column Chart
Steps to create the Stacked Column Chart:
Step 1: Initialize chart
Create a chart object by calling the worksheet.Charts.Add method and specify the chart type to ExcelChartType.Column_Stacked enum value.
C#
//Create the chart
IChartShape chart = worksheet.Charts.Add();
//Set chart type to Column_Stacked
chart.ChartType = ExcelChartType.Column_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:C6"];
//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 the below list of properties.
- ChartTitle of chart object.
- Set DataLabels via DefaultDataPoint.
- Set TRUE to chart’s HasLegend property, to show the legend.
C#
//Apply chart elements
//Set Chart Title
chart.ChartTitle = "Stacked Column Chart";
//Set Datalabels
IChartSerie serie1 = chart.Series[0];
serie1.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
serie1.DataPoints.DefaultDataPoint.DataLabels.Position = ExcelDataLabelPosition.Center;
//Set Legend
chart.HasLegend = true;
chart.Legend.Position = ExcelLegendPosition.Bottom;
Applicable Properties of Stacked Column Chart
Below is the list of other common properties that is applicable for a column/bar chart.
- GapWidth (value should be between 0 and 500)
- Overlap (value should be between -100 and 100)
- IsVarycolorNote:
Applying other properties apart from the above list might throw exception or the changes will not be reflected in the output document because those properties are not related to column/bar chart.

//Initialize chart
IChartShape chart = worksheet.Charts.Add();
chart.ChartType = ExcelChartType.Column_Stacked;
//Assign data
chart.DataRange = worksheet["A1:D6"];
chart.IsSeriesInRows = false;
//Apply chart elements
//Set Chart Title
chart.ChartTitle = "Stacked Column Chart";
//Set Datalabels
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;
serie1.DataPoints.DefaultDataPoint.DataLabels.Position = ExcelDataLabelPosition.Center;
serie2.DataPoints.DefaultDataPoint.DataLabels.Position = ExcelDataLabelPosition.Center;
serie3.DataPoints.DefaultDataPoint.DataLabels.Position = ExcelDataLabelPosition.Center;
//Set Legend
chart.HasLegend = true;
chart.Legend.Position = ExcelLegendPosition.Bottom;
//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);
workbook.Close();
}
}
