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 Gauges NuGet Package

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

Step 3: Register the handler

The 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 Syncfusion.Maui.Core.Hosting;
namespace GettingStarted
{
    public static class MauiProgram
    {
        public static MauiApp CreateMauiApp()
        {
            var builder = MauiApp.CreateBuilder();

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

            return builder.Build();
        }
    }
}

Step 4: Add .NET MAUI Linear gauge control

  1. To initialize the control, import the Syncfusion.Maui.Gauges namespace into your code.
  2. Initialize SfLinearGauge.
<ContentPage   
    . . .
    xmlns:gauge="clr-namespace:Syncfusion.Maui.Gauges;assembly=Syncfusion.Maui.Gauges">

    <gauge:SfLinearGauge />

</ContentPage>
using Syncfusion.Maui.Gauges;
. . .

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

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 Gauges 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.Gauges to install the Syncfusion® .NET MAUI Gauges NuGet package.
  4. To ensure all dependencies are installed, run dotnet restore.

Step 3: Register the handler

The 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 Syncfusion.Maui.Core.Hosting;
namespace GettingStarted
{
    public static class MauiProgram
    {
        public static MauiApp CreateMauiApp()
        {
            var builder = MauiApp.CreateBuilder();

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

            return builder.Build();
        }
    }
}

Step 4: Add .NET MAUI Linear gauge control

  1. To initialize the control, import the Syncfusion.Maui.Gauges namespace into your code.
  2. Initialize SfLinearGauge.
<ContentPage   
    . . .
    xmlns:gauge="clr-namespace:Syncfusion.Maui.Gauges;assembly=Syncfusion.Maui.Gauges">

    <gauge:SfLinearGauge />

</ContentPage>
using Syncfusion.Maui.Gauges;
. . .

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

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 Gauges NuGet Package

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

The 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 Syncfusion.Maui.Core.Hosting;
namespace GettingStarted
{
    public static class MauiProgram
    {
        public static MauiApp CreateMauiApp()
        {
            var builder = MauiApp.CreateBuilder();

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

            return builder.Build();
        }
    }
}

Step 4: Add .NET MAUI Linear gauge control

  1. To initialize the control, import the Syncfusion.Maui.Gauges namespace into your code.
  2. Initialize SfLinearGauge.
<ContentPage   
    . . .
    xmlns:gauge="clr-namespace:Syncfusion.Maui.Gauges;assembly=Syncfusion.Maui.Gauges">

    <gauge:SfLinearGauge />

</ContentPage>
using Syncfusion.Maui.Gauges;
. . .

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

Step 5: Add Pointers and Ranges

The .NET MAUI Linear Gauge is a data visualization control that displays values along a linear scale, with ranges highlighting value segments and pointers indicating specific values clearly.

<gauge:SfLinearGauge x:Name="gauge" >
                <gauge:SfLinearGauge.Ranges>
                    <gauge:LinearRange/>
                </gauge:SfLinearGauge.Ranges>

                <gauge:SfLinearGauge.MarkerPointers>
                    <gauge:LinearShapePointer Value="70"/>

                    <gauge:LinearContentPointer Value="80">
                        <gauge:LinearContentPointer.Content>
                            <Image Source="pin.png" HeightRequest="20" 
                                   WidthRequest="20"/>
                        </gauge:LinearContentPointer.Content>
                    </gauge:LinearContentPointer>
                </gauge:SfLinearGauge.MarkerPointers>

                <gauge:SfLinearGauge.BarPointers>
                    <gauge:BarPointer Value = "60"/>
                </gauge:SfLinearGauge.BarPointers>
            </gauge:SfLinearGauge>
SfLinearGauge gauge = new SfLinearGauge();
        
        LinearRange range = new LinearRange();
        gauge.Ranges.Add(range);
        
        LinearShapePointer shapePointer = new LinearShapePointer();
        shapePointer.Value = 70;
        gauge.MarkerPointers.Add(shapePointer);

        LinearContentPointer contentPointer = new LinearContentPointer();
        contentPointer.Value = 80;
        contentPointer.Content = new Image() { Source = "pin.png", HeightRequest = 20, WidthRequest = 20 };
        gauge.MarkerPointers.Add(contentPointer);

        BarPointer barPointer = new BarPointer();
        barPointer.Value = 60;
        gauge.BarPointers.Add(barPointer);

        this.Content = gauge;

The following screenshot illustrates the result of the above code.
