13 Jul 20266 minutes to read

This section explains the steps required to add the .NET MAUI Linear Gauge control and its elements such as scale, range, and pointer. This section covers only basic features needed to get started with the Syncfusion® .NET MAUI Linear Gauge control. The .NET MAUI Linear Gauge is supported on Windows, macOS, iOS, and Android. Follow the steps below to add a .NET MAUI Linear Gauge control to your project.

To get started quickly with our .NET MAUI Linear Gauge, you can check the following video.

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® 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.

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 press 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® 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 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 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 Syncfusion handler

Add the following namespace in the MauiProgram.cs file.

using Syncfusion.Maui.Core.Hosting;

Register the Syncfusion core handler in the CreateMauiApp method of the MauiProgram.cs file to use Syncfusion controls.

builder.ConfigureSyncfusionCore();

Step 4: Import the Gauges namespace

Add the following namespace in your XAML or C#.

xmlns:gauge="clr-namespace:Syncfusion.Maui.Gauges;assembly=Syncfusion.Maui.Gauges"
using Syncfusion.Maui.Gauges;

Step 5: Add a Linear Gauge with Pointers, Ranges, and Bar Pointers

Initialize the SfLinearGauge to show values on a linear scale, with ranges highlighting value segments and pointers indicating specific values clearly. The LinearRange highlights a value segment, the LinearShapePointer and LinearContentPointer are marker pointers, and the BarPointer is a shaded bar from the minimum scale value to the specified value.

NOTE

The image used in the LinearContentPointer source (e.g., pin.png) must be added to your project’s resources.

<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.
