Implementing Syncfusion WinUI Funnel Charts

The Syncfusion WinUI Funnel Chart (SfFunnelChart) is a specialized data visualization control for representing data that progressively decreases across stages in a process. It's ideal for analyzing conversion rates, sales pipelines, recruitment processes, and any workflow with sequential stages.

When to Use This Skill

Use this skill when the user needs to:

• Visualize conversion funnels - Sales pipelines, marketing campaigns, user acquisition flows
• Analyze process stages - Recruitment pipelines, order fulfillment, application workflows
• Display hierarchical data - Data that naturally decreases from stage to stage
• Create stage-based metrics - Performance tracking across sequential phases
• Implement interactive data exploration - With tooltips, selection, and segment explosion
• Customize visual appearance - Palettes, gradients, labels, legends, and styling

Component Overview

The SfFunnelChart is part of the Syncfusion.Chart.WinUI NuGet package and provides:

• Data binding with ItemsSource, XBindingPath, and YBindingPath
• Visual customization through titles, legends, data labels, and appearance settings
• Interactive features including tooltips, selection, and exploding segments
• Flexible rendering with multiple modes and layout options
• Rich styling using palettes, gradients, and custom templates

Here's a minimal example to create a funnel chart with legend and data labels:

XAML Implementation

<Window
    x:Class="FunnelChartDemo.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:chart="using:Syncfusion.UI.Xaml.Charts"
    xmlns:model="using:FunnelChartDemo.ViewModel">

    <chart:SfFunnelChart x:Name="chart"
                         Header="SALES PIPELINE"
                         EnableTooltip="True"
                         ShowDataLabels="True"
                         Height="400" Width="600"
                         ItemsSource="{Binding Data}"
                         XBindingPath="Stage"
                         YBindingPath="Value">
        
        <chart:SfFunnelChart.DataContext>
            <model:ChartViewModel />
        </chart:SfFunnelChart.DataContext>
        
        <chart:SfFunnelChart.Legend>
            <chart:ChartLegend />
        </chart:SfFunnelChart.Legend>
    </chart:SfFunnelChart>
</Window>

C# Implementation

using Syncfusion.UI.Xaml.Charts;

public sealed partial class MainWindow : Window
{
    public MainWindow()
    {
        this.InitializeComponent();
        
        SfFunnelChart chart = new SfFunnelChart();
        ChartViewModel viewModel = new ChartViewModel();
        chart.DataContext = viewModel;
        
        chart.SetBinding(
            SfFunnelChart.ItemsSourceProperty,
            new Binding() { Path = new PropertyPath("Data") });
        
        chart.XBindingPath = "Stage";
        chart.YBindingPath = "Value";
        chart.Header = "SALES PIPELINE";
        chart.Height = 400;
        chart.Width = 600;
        chart.Legend = new ChartLegend();
        chart.EnableTooltip = true;
        chart.ShowDataLabels = true;
        
        this.Content = chart;
    }
}

ViewModel

public class Model
{
    public string Stage { get; set; }
    public double Value { get; set; }
}

public class ChartViewModel
{
    public List<Model> Data { get; set; }
    
    public ChartViewModel()
    {
        Data = new List<Model>()
        {
            new Model() { Stage = "Leads", Value = 1000 },
            new Model() { Stage = "Qualified", Value = 750 },
            new Model() { Stage = "Proposal", Value = 500 },
            new Model() { Stage = "Negotiation", Value = 300 },
            new Model() { Stage = "Closed Won", Value = 150 }
        };
    }
}

Common Patterns

Pattern 1: Sales Funnel with Custom Colors

<Grid>
    <Grid.Resources>
        <BrushCollection x:Key="salesColors">
            <SolidColorBrush Color="#4dd0e1"/>
            <SolidColorBrush Color="#26c6da"/>
            <SolidColorBrush Color="#00bcd4"/>
            <SolidColorBrush Color="#0097a7"/>
            <SolidColorBrush Color="#00838f"/>
        </BrushCollection>
    </Grid.Resources>
    
    <chart:SfFunnelChart ItemsSource="{Binding Data}"
                         XBindingPath="Stage"
                         YBindingPath="Value"
                         PaletteBrushes="{StaticResource salesColors}"
                         ShowDataLabels="True">
        <chart:SfFunnelChart.DataLabelSettings>
            <chart:FunnelDataLabelSettings Context="Percentage" 
                                          Foreground="White" />
        </chart:SfFunnelChart.DataLabelSettings>
    </chart:SfFunnelChart>
</Grid>

Pattern 2: Interactive Funnel with Selection

<chart:SfFunnelChart ItemsSource="{Binding Data}"
                     XBindingPath="Stage"
                     YBindingPath="Value"
                     EnableTooltip="True">
    
    <chart:SfFunnelChart.SelectionBehavior>
        <chart:DataPointSelectionBehavior SelectionBrush="Orange"
                                         Type="Single"/>
    </chart:SfFunnelChart.SelectionBehavior>
    
    <chart:SfFunnelChart.TooltipBehavior>
        <chart:ChartTooltipBehavior />
    </chart:SfFunnelChart.TooltipBehavior>
</chart:SfFunnelChart>

Pattern 3: Exploded Segment Emphasis

<chart:SfFunnelChart ItemsSource="{Binding Data}"
                     XBindingPath="Stage"
                     YBindingPath="Value"
                     ExplodeIndex="2"
                     ExplodeOffset="40"
                     ExplodeOnTap="True"
                     GapRatio="0.1">
</chart:SfFunnelChart>
