Register Syncfusion® Blazor Service

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

@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.

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(serviceProvider => new HttpClient { BaseAddress = new Uri(builder.HostEnvironment.BaseAddress) });

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

Add script resources

The script can be accessed 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 Bullet Chart component

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

<SfBulletChart DataSource="@BulletChartData" ValueField="FieldValue" TargetField="TargetValue" Minimum="0" Maximum="300" Interval="50">
</SfBulletChart>

@code{
    public class ChartData
    {
        public double FieldValue { get; set; }
        public double TargetValue { get; set; }
    }
    public List<ChartData> BulletChartData = new List<ChartData>
    {
        new ChartData { FieldValue = 270, TargetValue = 250 }
    };
}
  • Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to launch the application. This will render the Syncfusion® Blazor Bullet Chart component in your default web browser.

    <BulletChartRangeCollection>
        <BulletChartRange End=150> </BulletChartRange>
