Getting Started with Blazor Smith Chart Component

30 Jan 202414 minutes to read

This section briefly explains about how to include Blazor Smith Chart component in your Blazor Server App and Blazor WebAssembly App using Visual Studio.

Prerequisites

System requirements for Blazor components

Create a new Blazor App in Visual Studio

You can create a Blazor Server App or Blazor WebAssembly App using Visual Studio via Microsoft Templates or the Syncfusion Blazor Extension.

Install Syncfusion Blazor SmithChart NuGet in the App

To add Blazor Smith Chart component in the app, open the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), search and install Syncfusion.Blazor.SmithChart. Alternatively, you can utilize the following package manager command to achieve the same.

Package Manager
Install-Package Syncfusion.Blazor.SmithChart -Version 25.1.35

NOTE

Syncfusion Blazor components are available in nuget.org. Refer to NuGet packages topic for available NuGet packages list with component details.

Register Syncfusion Blazor Service

Open ~/_Imports.razor file and import the Syncfusion.Blazor and Syncfusion.Blazor.Charts namespace.

~/_Imports.razor

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

Now, register the Syncfusion Blazor Service in the ~/Program.cs file of your Blazor Server App or Blazor WebAssembly App.

Blazor Server App
Blazor WebAssembly App
using Microsoft.AspNetCore.Components;
using Microsoft.AspNetCore.Components.Web;
using Syncfusion.Blazor;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddRazorPages();
builder.Services.AddServerSideBlazor();
builder.Services.AddSyncfusionBlazor();

var app = builder.Build();
....
using Microsoft.AspNetCore.Components.Web;
using Microsoft.AspNetCore.Components.WebAssembly.Hosting;
using Syncfusion.Blazor;

var builder = WebAssemblyHostBuilder.CreateDefault(args);
builder.RootComponents.Add<App>("#app");
builder.RootComponents.Add<HeadOutlet>("head::after");

builder.Services.AddScoped(sp => new HttpClient { BaseAddress = new Uri(builder.HostEnvironment.BaseAddress) });

builder.Services.AddSyncfusionBlazor();
await builder.Build().RunAsync();
....

Add script resources

The script can be accessed from NuGet through Static Web Assets. Reference the script in the <head> of the main page as follows:

For .NET 6 Blazor Server app, include it in ~/Pages/_Layout.cshtml file.
For .NET 7 Blazor Server app, include it in the ~/Pages/_Host.cshtml file.
For Blazor WebAssembly app, include it in the ~/index.html file.

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

NOTE

Check out the Adding Script Reference topic to learn different approaches for adding script references in your Blazor application.

Add Blazor Smith Chart component

Add the Syncfusion Blazor Smith Chart component in the ~/Pages/Index.razor file.

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.

<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 }
    };
}

Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to launch the application. This will render the Syncfusion Blazor Smith Chart component in your default web browser.
