Getting Started with Blazor Smith Chart in Blazor Web App

15 Jul 202616 minutes to read

This section briefly explains how to include the Blazor Smith Chart component in your Blazor Web App using Visual Studio, Visual Studio Code, and the .NET CLI.

Create a new Blazor Web App

Create a Blazor Web App using Visual Studio via Microsoft Templates or the Blazor Extension. For detailed instructions, refer to the Blazor Web App Getting Started documentation.

Run the following command to create a new Blazor Web App.

dotnet new blazor -o BlazorWebApp --interactivity Auto
cd BlazorWebApp
cd BlazorWebApp.Client

Alternatively, create a Blazor Web App using Visual Studio Code via Microsoft Templates, the Blazor Extension, or the C# Dev Kit extension.

Run the following command to create a new Blazor Web App.

dotnet new blazor -o BlazorWebApp --interactivity Auto
cd BlazorWebApp
cd BlazorWebApp.Client

NOTE

Configure the appropriate Interactive render mode and Interactivity location while creating a Blazor Web App. For detailed information, refer to the interactive render mode documentation.

Install the required Blazor package

Install the Syncfusion.Blazor.SmithChart NuGet package. All Syncfusion Blazor packages are available on nuget.org. See the NuGet packages topic for details. If using the WebAssembly or Auto render modes in the Blazor Web App, install this package in the .Client project.

  1. Go to Tools → NuGet Package Manager → Manage NuGet Packages for Solution.
  2. Search the required NuGet package (Syncfusion.Blazor.SmithChart) and install it.

Alternatively, you can install the same package using the Package Manager Console with the following command.

Install-Package Syncfusion.Blazor.SmithChart -Version 34.1.29

Open the terminal and run the following command.

dotnet add package Syncfusion.Blazor.SmithChart -v 34.1.29

Open the command prompt and run the following command.

dotnet add package Syncfusion.Blazor.SmithChart -v 34.1.29

Add import namespaces

After the package is installed, open the ~/_Imports.razor file in the .Client project and import the Syncfusion.Blazor and Syncfusion.Blazor.Charts namespaces.

@using Syncfusion.Blazor
@using Syncfusion.Blazor.Charts

Register the Blazor service

Open the Program.cs file in Blazor Web App and register the Blazor service. If the Interactive Render Mode is set to WebAssembly or Auto, register the Blazor service in Program.cs files of both the server and client projects in your Blazor Web App.

....
using Syncfusion.Blazor;
....
builder.Services.AddSyncfusionBlazor();
....

Add script resource

The script can be accessed from NuGet through Static Web Assets. Include the script references in the App.razor file.

<script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>

Add Blazor Smith Chart component

Open a Razor file located in the ~/Pages/*.razor (for example, Home.razor) and add the Blazor Smith Chart component inside the .Client project razor file.

NOTE

If the interactivity location is set to Per page/component in the Web App, define a render mode at the top of the razor file. (For example, InteractiveServer, InteractiveWebAssembly or InteractiveAuto). If the Interactivity is set to Global with Auto or WebAssembly, the render mode is automatically configured in the App.razor file by default.

@rendermode InteractiveAuto

@using Syncfusion.Blazor.Charts

Adding series to Blazor Smith Chart

Smith Chart series can be added in two ways. Use either Points or Datasource in the SmithChartSeries.

If you add using Datasource property, additionally you need to specify data source mapping fields using Reactance and Resistance properties.

If you are using Points, you don’t need to specify mapping fields as like in DataSource. But the Points collection should be SmithChartPoint type and define Resistance and Reactance properties mandatorily.

The following sample demonstrates adding two series to Smith Chart in both ways.

  • First series Transmission1 shows DataSource bound series.
  • Second series Transmission2 shows Points bound series.
@using Syncfusion.Blazor.Charts

<SfSmithChart>
    <SmithChartSeriesCollection>
        <SmithChartSeries Name="Transmission1"
                          Reactance="Reactance"
                          Resistance="Resistance"
                          DataSource="@FirstTransmissionSeries">
        </SmithChartSeries>
        <SmithChartSeries Name="Transmission2"
                          Points="@SecondTransmissionSeries">
        </SmithChartSeries>
    </SmithChartSeriesCollection>
</SfSmithChart>

@code {
    public class SmithDataSource
    {
        public double Resistance { get; set; }
        public double Reactance { get; set; }
    };
    public List<SmithDataSource> FirstTransmissionSeries = new List<SmithDataSource> {
        new SmithDataSource { Resistance= 10, Reactance= 25 },
        new SmithDataSource { Resistance= 8, Reactance= 6 },
        new SmithDataSource { Resistance= 6, Reactance= 4.5 },
        new SmithDataSource { Resistance= 4.5, Reactance= 2 },
        new SmithDataSource { Resistance= 3.5, Reactance= 1.6 },
        new SmithDataSource { Resistance= 2.5, Reactance= 1.3 },
        new SmithDataSource { Resistance= 2, Reactance= 1.2 },
        new SmithDataSource { Resistance= 1.5, Reactance= 1 },
        new SmithDataSource { Resistance= 1, Reactance= 0.8 },
        new SmithDataSource { Resistance= 0.5, Reactance= 0.4 },
        new SmithDataSource { Resistance= 0.3, Reactance= 0.2 },
        new SmithDataSource { Resistance= 0.001, Reactance= 0.15 }
    };
    public List<SmithChartPoint> SecondTransmissionSeries = new List<SmithChartPoint> {
        new SmithChartPoint { Resistance= 20, Reactance= -50 },
        new SmithChartPoint { Resistance= 10, Reactance= -10 },
        new SmithChartPoint { Resistance= 9, Reactance= -4.5 },
        new SmithChartPoint { Resistance= 8, Reactance= -3.5 },
        new SmithChartPoint { Resistance= 7, Reactance= -2.5 },
        new SmithChartPoint { Resistance= 6, Reactance= -1.5 },
        new SmithChartPoint { Resistance= 5, Reactance= -1 },
        new SmithChartPoint { Resistance= 4.5, Reactance= -0.5 },
        new SmithChartPoint { Resistance= 2, Reactance= 0.5 },
        new SmithChartPoint { Resistance= 1.5, Reactance= 0.4 },
        new SmithChartPoint { Resistance= 1, Reactance= 0.4 },
        new SmithChartPoint { Resistance= 0.5, Reactance= 0.2 },
        new SmithChartPoint { Resistance= 0.3, Reactance= 0.1 },
        new SmithChartPoint { Resistance= 0.001, Reactance= 0.05 }
    };
}
