Create a new Blazor WebAssembly (Standalone) App

Create a Blazor WebAssembly App using Visual Studio via Microsoft Templates or the Blazor Extension.

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

dotnet new blazorwasm -o BlazorApp
cd BlazorApp

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

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

dotnet new blazorwasm -o BlazorApp
cd BlazorApp

Install the required Blazor package

Install the Syncfusion.Blazor.Charts NuGet package. All Syncfusion Blazor packages are available on nuget.org. See the NuGet packages topic for details.

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

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

Install-Package Syncfusion.Blazor.Charts -Version 34.1.29

Open the terminal and run the following commands.

dotnet add package Syncfusion.Blazor.Charts -v 34.1.29

Open the command prompt and run the following commands.

dotnet add package Syncfusion.Blazor.Charts -v 34.1.29

Add import namespaces

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

NOTE

The ~/ notation represents the root directory of your project. This file is typically located in your project’s root folder.

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

Register the Blazor service

Open the Program.cs file in Blazor WebAssembly App and register the Blazor service.

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

Add script resources

The script can be accessed from NuGet through Static Web Assets. Include the script references in the ~wwwroot/index.html file.

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

Add Blazor Charts component

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

<!-- SfChart is the root container component for the chart -->
<SfChart>

</SfChart>

Run the application

Press Ctrl+F5 (Windows) or +F5 (macOS) to launch the application. The Blazor Charts component will render in your default web browser.

Open the terminal and run the following command.

dotnet run

Open the command prompt and run the following command.

dotnet run
Blazor Chart Component

Populate Blazor Charts with data

To bind data for the Blazor charts component, you can assign an IEnumerable object to the DataSource property. It can also be provided as an instance of the DataManager.

Map the data fields Month and SalesValue to the series XName and YName properties, then set the data to the DataSource property, and the chart type to Column because we will be viewing the data in a column chart.

@using Syncfusion.Blazor.Charts

<SfChart>
    <!-- ChartPrimaryXAxis configures the X-axis properties such as value type and labels -->
    <ChartPrimaryXAxis ValueType="Syncfusion.Blazor.Charts.ValueType.Category"></ChartPrimaryXAxis>
    <!-- ChartSeriesCollection contains one or more data series to be plotted on the chart -->
    <ChartSeriesCollection>
        <!-- ChartSeries defines a data series with its data source and axis mappings -->
        <ChartSeries DataSource="@Sales" XName="Month" YName="SalesValue" Type="ChartSeriesType.Column">
        </ChartSeries>
    </ChartSeriesCollection>
</SfChart>

@code 
{
    public class SalesInfo
    {
        public string Month { get; set;}
        public double SalesValue { get; set;}
    }

    public List<SalesInfo> Sales = new List<SalesInfo>
    {
        new SalesInfo { Month = "Jan", SalesValue = 35 },
        new SalesInfo { Month = "Feb", SalesValue = 28 },
        new SalesInfo { Month = "Mar", SalesValue = 34 },
        new SalesInfo { Month = "Apr", SalesValue = 32 },
        new SalesInfo { Month = "May", SalesValue = 40 },
        new SalesInfo { Month = "Jun", SalesValue = 32 },
        new SalesInfo { Month = "Jul", SalesValue = 35 }
    };
}
