Prerequisites

Before proceeding, ensure the following are set up:

  1. Install .NET 9 SDK or later.
  2. Set up a .NET MAUI environment with Visual Studio 2022 v17.12 or later.

Step 1: Create a new .NET MAUI project

  1. Go to File > New > Project and choose the .NET MAUI App template.
  2. Name the project and choose a location. Click Next.
  3. Select the .NET framework version and click Create.

Step 2: Install the Syncfusion® .NET MAUI Charts Package

  1. In Solution Explorer, right-click the project and choose Manage NuGet Packages.
  2. Search for Syncfusion.Maui.Charts and install the latest version.
  3. Ensure the necessary dependencies are installed correctly, and the project is restored.

Step 3: Register the handler

Syncfusion.Maui.Core nuget is a dependent package for all Syncfusion® controls of .NET MAUI. In the MauiProgram.cs file, register the handler for Syncfusion® core.

using Microsoft.Maui;
using Microsoft.Maui.Hosting;
using Microsoft.Maui.Controls.Compatibility;
using Microsoft.Maui.Controls.Hosting;
using Microsoft.Maui.Controls.Xaml;
using Syncfusion.Maui.Core.Hosting;

namespace ChartGettingStarted
{
    public static class MauiProgram
    {
        public static MauiApp CreateMauiApp()
        {
            var builder = MauiApp.CreateBuilder();
            builder
            .UseMauiApp<App>()
            .ConfigureSyncfusionCore()
            .ConfigureFonts(fonts =>
            {
                fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
            });

            return builder.Build();
        }
    }
}

Step 4: Add .NET MAUI Funnel Chart

  1. To initialize the control, import the Syncfusion.Maui.Charts namespace.
  2. Initialize SfFunnelChart.
<ContentPage   
    . . .
    xmlns:chart="clr-namespace:Syncfusion.Maui.Charts;assembly=Syncfusion.Maui.Charts">

    <chart:SfFunnelChart/>
</ContentPage>
using Syncfusion.Maui.Charts;
. . .

public partial class MainPage : ContentPage
{
    public MainPage()
    {
        this.InitializeComponent();
        SfFunnelChart chart = new SfFunnelChart();
        this.Content = chart;
    }
}

        {
            var builder = MauiApp.CreateBuilder();
            builder
            .UseMauiApp<App>()
            .ConfigureSyncfusionCore()
            .ConfigureFonts(fonts =>
            {
                fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");

    xmlns:chart="clr-namespace:Syncfusion.Maui.Charts;assembly=Syncfusion.Maui.Charts">

    <chart:SfFunnelChart/>
</ContentPage>
using Syncfusion.Maui.Charts;
. . .

public partial class MainPage : ContentPage
{
    public MainPage()
    {
        this.InitializeComponent();
        SfFunnelChart chart = new SfFunnelChart();
        this.Content = chart;
    }
}

Prerequisites

Before proceeding, ensure the following are set up:

  1. Install .NET 9 SDK or later.
  2. Set up a .NET MAUI environment with JetBrains Rider 2024.3 or later.

  2. Search for Syncfusion.Maui.Charts and install the latest version.
  3. Ensure the necessary dependencies are installed correctly, and the project is restored. If not, Open the Terminal in Rider and manually run: dotnet restore

Step 3: Register the handler

Syncfusion.Maui.Core nuget is a dependent package for all Syncfusion® controls of .NET MAUI. In the MauiProgram.cs file, register the handler for Syncfusion® core.

using Microsoft.Maui;
using Microsoft.Maui.Hosting;
using Microsoft.Maui.Controls.Compatibility;
using Microsoft.Maui.Controls.Hosting;
using Microsoft.Maui.Controls.Xaml;
using Syncfusion.Maui.Core.Hosting;

namespace ChartGettingStarted
{
    public static class MauiProgram
    {
        public static MauiApp CreateMauiApp()
        {
            var builder = MauiApp.CreateBuilder();
            builder
            .UseMauiApp<App>()
            .ConfigureSyncfusionCore()
            .ConfigureFonts(fonts =>
            {
                fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
            });

            return builder.Build();
        }
    }
}

Step 4: Add .NET MAUI Funnel Chart

  1. To initialize the control, import the Syncfusion.Maui.Charts namespace.
  2. Initialize SfFunnelChart.
<ContentPage   
    . . .
    xmlns:chart="clr-namespace:Syncfusion.Maui.Charts;assembly=Syncfusion.Maui.Charts">

    <chart:SfFunnelChart/>
</ContentPage>
using Syncfusion.Maui.Charts;
. . .

public partial class MainPage : ContentPage
{
    public MainPage()
    {
        this.InitializeComponent();
        SfFunnelChart chart = new SfFunnelChart();
        this.Content = chart;
    }
}

Step 5: Initialize view model

Now, let us define a simple data model that represents a data point in the chart.

public class AdmissionModel
{
    public string XValue { get; set; }
    public double YValue { get; set; }
}

Next, create a view AdmissionViewModel class and initialize a list of AdmissionModel objects as follows.

public class AdmissionViewModel
{
    public List<AdmissionModel> Data { get; set; }

    public AdmissionViewModel()
    {
        Data = new List<AdmissionModel>()
        {
            new AdmissionModel() {XValue = "Enrolled", YValue=175},
            new AdmissionModel() {XValue = "Admits", YValue=190},
            new AdmissionModel() {XValue = "Applicants", YValue=245},
            new AdmissionModel() {XValue = "Inquiries ", YValue=290},
            new AdmissionModel() {XValue = "Prospects ", YValue=320},
        };
    }
}

Create a AdmissionViewModel instance and set it as the chart’s BindingContext. This enables property binding from AdmissionViewModel class.

NOTE

Add the namespace of AdmissionViewModel class to your XAML Page, if you prefer to set BindingContext in XAML.

<ContentPage
    . . .
    xmlns:chart="clr-namespace:Syncfusion.Maui.Charts;assembly=Syncfusion.Maui.Charts"
    xmlns:model="clr-namespace:ChartGettingStarted">

    <chart:SfFunnelChart>
        <chart:SfFunnelChart.BindingContext>
            <model:AdmissionViewModel/>
        </chart:SfFunnelChart.BindingContext>
    </chart:SfFunnelChart>
</ContentPage>
SfFunnelChart chart = new SfFunnelChart();
AdmissionViewModel viewModel = new AdmissionViewModel();
chart.BindingContext = viewModel;

Step 6: Populate chart with data

Binding Data to the funnel chart ItemsSource property from its BindingContext to create our own funnel chart.

<chart:SfFunnelChart ItemsSource="{Binding Data}" 
                        XBindingPath="XValue" 
                        YBindingPath="YValue"
                        ShowDataLabels="True" 
                        EnableTooltip="True">

    <chart:SfFunnelChart.Title>
        <Label Text="School Admission"/>
    </chart:SfFunnelChart.Title>

    <chart:SfFunnelChart.BindingContext>
        <model:AdmissionViewModel/>
    </chart:SfFunnelChart.BindingContext>

    <chart:SfFunnelChart.Legend>
        <chart:ChartLegend/>
    </chart:SfFunnelChart.Legend>

</chart:SfFunnelChart>
using Syncfusion.Maui.Charts;
. . .
public partial class MainPage : ContentPage
{   
    public MainWindow()
    {
        SfFunnelChart chart = new SfFunnelChart();
        chart.Title = new Label()
        {
            Text = "School Admission"
        };
        chart.Legend = new ChartLegend();
        AdmissionViewModel viewModel = new AdmissionViewModel();
        chart.BindingContext = viewModel;

        chart.ItemsSource = viewModel.Data;
        chart.XBindingPath = "XValue";
        chart.YBindingPath = "YValue";
        chart.EnableTooltip = true;
        chart.ShowDataLabels = true;
        this.Content = chart;
    }
}

The following screenshot illustrates the result of the above code.
