Getting Started with .NET MAUI Circular Chart

This section explains how to populate the Circular Chart with data, including adding a title, data labels, a legend, and tooltips. Additionally, it covers the essential aspects to get started with the Circular 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 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. Then click Next.
  3. Select the .NET framework version and click Create.

Step 2: Install the Syncfusion® .NET MAUI Toolkit NuGet package

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

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 Code.
  3. Ensure that the .NET MAUI workloads are installed and configured as described here.

Step 1: Create a new .NET MAUI project

  1. Open the command palette by pressing Ctrl+Shift+P and type .NET:New Project and enter.
  2. Choose the .NET MAUI App template.
  3. Select the project location, type the project name and press Enter.
  4. Then choose Create project.

Step 2: Install the Syncfusion® .NET MAUI Toolkit NuGet package

  1. Press Ctrl + ` (backtick) to open the integrated terminal in Visual Studio Code.
  2. Ensure you’re in the project root directory where your .csproj file is located.
  3. Run the command dotnet add package Syncfusion.Maui.Toolkit to install the Syncfusion® .NET MAUI Toolkit NuGet package.
  4. To ensure all dependencies are installed, run dotnet restore.

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.
  3. Make sure the MAUI workloads are installed and configured as described here.

Step 1: Create a new .NET MAUI project

  1. Go to File > New Solution, Select .NET (C#) and choose the .NET MAUI App template.
  2. Enter the Project Name, Solution Name, and Location.
  3. Select the .NET framework version and click Create.

Step 2: Install the Syncfusion® MAUI Toolkit NuGet package

  1. In Solution Explorer, right-click the project and choose Manage NuGet Packages.
  2. Search for Syncfusion.Maui.Toolkit 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

Make sure to add the namespace.

using Syncfusion.Maui.Toolkit.Hosting;
Register the Syncfusion core handler in your CreateMauiApp method of `MauiProgram.cs` file to use Syncfusion controls. 
builder.ConfigureSyncfusionToolkit();

Step 4: Initialize view model

Define a simple data model to represent a data point in the chart:

public class SalesModel
{
    public string Product { get; set; }
    public double SalesRate { get; set; }
}

Next, create a SalesViewModel class and initialize a list of SalesModel objects:

public class SalesViewModel
{
    public List<SalesModel> Data { get; set; }

    public SalesViewModel()
    {
        Data = new List<SalesModel>()
        {
            new SalesModel(){Product = "iPad", SalesRate = 25},
            new SalesModel(){Product = "iPhone", SalesRate = 35},
            new SalesModel(){Product = "MacBook", SalesRate = 15},
            new SalesModel(){Product = "Mac", SalesRate = 5},
            new SalesModel(){Product = "Others", SalesRate = 10},
        };
    }
}

Step 5: Import Circular ProgressBar namespace

Add the following namespace in your XAML or C#.

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

Step 6: Add the Circular Chart component

Adding PieSeries to the charts Series collection and binding Data to the series ItemsSource property from its BindingContext to create our own Product Sales Pie chart.

NOTE

The circular chart has Series as its default content.

NOTE

To plot the series, the XBindingPath and YBindingPath properties must be configured so that the chart may get values from the respective properties in the data model.

<chart:SfCircularChart>
    <chart:SfCircularChart.Title>
        <Label Text="PRODUCT SALES"/>
    </chart:SfCircularChart.Title>
    <chart:SfCircularChart.BindingContext>
        <model:SalesViewModel/>
    </chart:SfCircularChart.BindingContext>
    <chart:SfCircularChart.Legend>
        <chart:ChartLegend/>
    </chart:SfCircularChart.Legend>
    <chart:PieSeries ItemsSource="{Binding Data}"
                    ShowDataLabels="True"
                    XBindingPath="Product"
                    EnableTooltip="True"
                    YBindingPath="SalesRate"/>
    </chart:SfCircularChart>
SfCircularChart chart = new SfCircularChart();

chart.Title = new Label()
{
    Text = "PRODUCT SALES"
};

chart.Legend = new ChartLegend();
SalesViewModel viewModel = new SalesViewModel();
chart.BindingContext = viewModel;
PieSeries series = new PieSeries();
series.ItemsSource = viewModel.Data;
series.XBindingPath = "Product";
series.YBindingPath = "SalesRate";
series.EnableTooltip = true;
series.ShowDataLabels = true;
chart.Series.Add(series);
this.Content = chart;
