This article explains how to create 100% Stacked Pyramid Chart in Excel using Syncfusion Excel (XlsIO) library. What is 100% Stacked 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 100% stacked pyramid chart, each series is vertically stacked one over the other and the total(cumulative) of each bar always equals to 100%.
100% Stacked Pyramid Chart To create 100% stacked pyramid chart in Excel using XlsIO, you need to do the following steps. Steps to create 100% Stacked Pyramid Chart:Step 1: Initialize chartCreate a chart object by calling the worksheet.Charts.Add method and specify the chart type to ExcelChartType.Pyramid_Stacked_100 enumeration value. C# //Create the chart IChartShape chart = worksheet.Charts.Add(); //Set chart type to Pyramid_Stacked_100 chart.ChartType = ExcelChartType.Pyramid_Stacked_100;
Step 2: Assign dataSet 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 elementsAdd the basic elements like chart title, data labels and legend with below list of properties.
C# //Set chart title chart.ChartTitle = "100% Stacked 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 elementsAdd the 3D chart elements like rotation and elevation.
C# //Set rotation and elevation chart.Rotation = 50; chart.Elevation = 20;
Applicable properties for 100% Stacked Pyramid ChartBelow is the list of other common properties applicable for 100% stacked pyramid chart.
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 100% stacked pyramid chart. To know more about creating charts with various settings using Syncfusion Excel (XlsIO) library, please refer the documentation. The following C#/ VB.NET complete code snippet shows the creation of 100% stacked pyramid 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.Pyramid_Stacked_100;
//Assign data
chart.DataRange = worksheet["A1:D6"];
chart.IsSeriesInRows = false;
//Apply chart elements
//Set chart title
chart.ChartTitle = "100% Stacked Pyramid Chart";
//Set legend
chart.HasLegend = true;
chart.Legend.Position = ExcelLegendPosition.Bottom;
//Set rotation and elevation
chart.Rotation = 50;
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);
}
}
}
