How to Create a Funnel Chart in Using WinForms Excel Library?
This article explains how to create a funnel chart in Excel using the Syncfusion® Excel (XlsIO) library.
What is a funnel chart?
A funnel chart shows a process that starts at the initial state and ends with a final state, where it is noticeable in which stages the fallout happens and by what magnitude.
Funnel Chart
To create a funnel chart in Excel using XlsIO, you need to follow these steps:
Steps to create a funnel chart:
Step 1: Initialize the chart
Create a chart object by calling the worksheet.Charts.Add method and specify the chart type as ExcelChartType.Funnel enum value.
C#
// Create the chart IChartShape chart = worksheet.Charts.Add(); // Set chart type to Funnel chart.ChartType = ExcelChartType.Funnel;
Step 2: Assign data
Set a range of data from the worksheet to the chart’s DataRange property. To plot the series values in a column and categories in a row, set the chart’s IsSeriesInRows property to false.
C#
// Set region of Chart data chart.DataRange = worksheet["A1:B6"]; // 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 using the properties listed below:
- ChartTitle of the chart object.
- Set DataLabels via DefaultDataPoint.
- Set TRUE to the chart’s HasLegend property, to show the legend.
C#
// Apply chart elements // Set Chart Title chart.ChartTitle = "Funnel Chart"; // Set Legend chart.HasLegend = false; // Set DataLabels IChartSerie serie = chart.Series[0]; serie.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
Applicable properties of funnel chart
Below is the list of other properties that is applicable for a funnel chart.
- GapWidthNote:
- Applying other properties unrelated to this chart might throw exception or the changes will not be reflected in the output document because those properties are not related to funnel chart.
- As funnel chart is introduced in MS Excel 2016, it can’t be viewed in MS Excel 2013 and its earlier versions.
To know more about creating charts with various settings using the Syncfusion® Excel (XlsIO) library, please refer the documentation.
The following C#/ VB.NET complete code snippet shows the creation of a funnel 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.Funnel;
// Assign data
chart.DataRange = worksheet["A1:B6"];
chart.IsSeriesInRows = false;
// Apply chart elements
// Set Chart Title
chart.ChartTitle = "Funnel Chart";
// Set Datalabels
IChartSerie serie1 = chart.Series[0];
serie1.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
// Set Legend
chart.HasLegend = false;
// 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);
}
}
}
}
VB.NET
Imports Syncfusion.XlsIO
Imports System.Reflection
Imports System.IO
Namespace ChartSample
Class Program
Public Shared Sub Main(ByVal args As String())
Using excelEngine As ExcelEngine = New ExcelEngine()
Dim application As IApplication = excelEngine.Excel
application.DefaultVersion = ExcelVersion.Excel2016
'Open existing workbook with data entered
Dim assembly As Assembly = GetType(Program).GetTypeInfo.Assembly
Dim fileStream As Stream = assembly.GetManifestResourceStream("ChartSample.InputTemplate.xlsx")
Dim workbook As IWorkbook = application.Workbooks.Open(fileStream)
Dim worksheet As IWorksheet = workbook.Worksheets(0)
'Initialize chart
Dim chart As IChartShape = worksheet.Charts.Add
chart.ChartType = ExcelChartType.Funnel
'Assign data
chart.DataRange = worksheet("A1:B6")
chart.IsSeriesInRows = False
'Apply chart elements
'Set Chart Title
chart.ChartTitle = "Funnel Chart"
'Set Datalabels
Dim serie1 As IChartSerie = chart.Series(0)
serie1.DataPoints.DefaultDataPoint.DataLabels.IsValue = True
'Set Legend
chart.HasLegend = False
'Positioning the chart in the worksheet
chart.TopRow = 8
chart.LeftColumn = 1
chart.BottomRow = 23
chart.RightColumn = 8
'Saving and closing the workbook
Dim stream As Stream = File.Create("Output.xlsx")
workbook.SaveAs(stream)
End Sub
End Class
End Namespace
