This article explains how to create a 100% Stacked area chart in Excel using Syncfusion Excel (XlsIO) library.

To create a 100% Stacked area chart in Excel using XlsIO, you need to do the following steps.

Create 100% Area Stacked Chart in Excel

100% Stacked Area Chart

Steps to create Stacked Area Chart:

Step 1: Initialize chart

Create a chart object by calling the worksheet.Charts.Add method and specify the chart type to ExcelChartType.Area_Stacked_100 enum value.

            //Create the chart
            IChartShape chart = worksheet.Charts.Add();
 
            //Set chart type to Area_Stacked_100
            chart.ChartType = ExcelChartType.Area_Stacked_100;

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 and legend.

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

              //Apply chart elements
              //Set Chart Title
              chart.ChartTitle = "100% Stacked Area Chart";
 
              //Set Legend
              chart.HasLegend = true;
              chart.Legend.Position = ExcelLegendPosition.Bottom;

Applicable properties for 100% Stacked area chart

Common property applicable for 100% Stacked area chart is

IsVarycolor (This property holds good for single series chart).

Note:

Applying other properties apart from the above mentioned property might throw exception or the changes will not be reflected in the output document because those properties are not related to area chart.

            {
                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.Area_Stacked_100;
 
                //Assign data
                chart.DataRange = worksheet["A1:D6"];
                chart.IsSeriesInRows = false;
 
                //Apply chart elements
                //Set Chart Title
                chart.ChartTitle = "100% Stacked Area Chart";
 
                //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();
            }
        }
