dotnet restoreNOTE
Syncfusion® Blazor components are available in nuget.org. Refer to the NuGet packages topic for the available NuGet packages list with component details.
Add Import Namespaces
Open the ~/_Imports.razor file from the client project and import the Syncfusion.Blazor and Syncfusion.Blazor.Charts namespaces.
@using Syncfusion.Blazor
@using Syncfusion.Blazor.ChartsRegister Syncfusion® Blazor Service
Register the Syncfusion® Blazor Service in the ~/Program.cs file of your Blazor Web App.
If the Interactive Render Mode is set to WebAssembly or Auto, register the Syncfusion® Blazor service in the ~/Program.cs files of the main server project and associated .Client project.
...
...
using Syncfusion.Blazor;
var builder = WebApplication.CreateBuilder(args);
// Add services to the container.
builder.Services.AddRazorComponents()
.AddInteractiveServerComponents()
.AddInteractiveWebAssemblyComponents();
builder.Services.AddSyncfusionBlazor();
var app = builder.Build();
.......
using Syncfusion.Blazor;
var builder = WebAssemblyHostBuilder.CreateDefault(args);
builder.Services.AddSyncfusionBlazor();
await builder.Build().RunAsync();Add script resources
The script can be accessed from NuGet through Static Web Assets. Include the script reference at the end of the <body> in the ~/Components/App.razor file as shown below:
<body>
....
<script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>
</body>NOTE
Check out the Adding Script Reference topic to learn different approaches for adding script references in your Blazor application.
Add Syncfusion® Blazor Smith Chart component
Add the Syncfusion® Blazor Smith Chart component to a Razor page located under the Pages folder (e.g., Pages/Home.razor) in either the Server or Client project. If an interactivity location as Per page/component in the web app, define a render mode at top of the component, as follows:
| Interactivity location | RenderMode | Code |
|---|---|---|
| Per page/component | Auto | @rendermode InteractiveAuto |
| WebAssembly | @rendermode InteractiveWebAssembly | |
| None | — |
NOTE
If an Interactivity Location is set to
Globaland the Render Mode is set toAutoorWebAssembly, the render mode is configured in theApp.razorfile by default.
@* desired render mode define here *@

</SfSmithchart>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
Transmission1showsDataSourcebound series. - Second series
Transmission2showsPointsbound 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 the default web browser.
