How to Create WinForms Excel 100% Stacked Bar Cone Chart in C#, VB.NET?
This article explains how to create a 100% Stacked Bar Cone Chart in Excel using Syncfusion® WinForms Excel.
What is a 100% 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 100% stacked bar cone chart, each series is horizontally stacked one after the other and the total (cumulative) of each bar always equals to 100%.
100% Stacked Bar Cone Chart
To create 100% stacked bar cone chart in Excel using XlsIO, you need to follow the steps below:
Steps to create a 100% 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_100 enumeration value.
C#
// Create the chart IChartShape chart = worksheet.Charts.Add(); // Set chart type to Cone_Bar_Stacked_100 chart.ChartType = ExcelChartType.Cone_Bar_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 columns and categories in rows, set the 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 basic elements like the chart title, data labels and legend using the properties below.
- 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 = "100% 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 100% Stacked Bar Cone Chart
Below is the list of other common properties applicable for 100% 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 100% stacked bar cone 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 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_100;
// Assign data
chart.DataRange = worksheet["A1:D6"];
chart.IsSeriesInRows = false;
// Apply chart elements
// Set chart title
chart.ChartTitle = "100% 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);
}
}
}
}
