Add Import Namespaces

Open the ~/_Imports.razor file and import the Syncfusion.Blazor and Syncfusion.Blazor.ChartWizard namespaces.

~/_Imports.razor

@using Syncfusion.Blazor
@using Syncfusion.Blazor.ChartWizard

Register Syncfusion^® Blazor Service

Register the Syncfusion^® Blazor Service in the ~/Program.cs file of the Blazor WebAssembly App.

Blazor WebAssembly App

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. Include the script reference within the <head> section of the ~/index.html file.

<head>
    ....
    <script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>
    <!-- Blazor Chart Wizard Component script reference.-->
     <!-- <script src="_content/Syncfusion.Blazor.ChartWizard/scripts/sf-chart-wizard.min.js" type="text/javascript"></script> -->
</head>

NOTE

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

Add Blazor Chart Wizard Component

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

RAZOR

<SfChartWizard>

</SfChartWizard>

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

Populate Blazor Chart Wizard data

To bind data for the Chart Wizard component, you can assign a IEnumerable object to the DataSource property.

RAZOR

public class OlympicsData
{
    public string? Country { get; set; }
    public string? CountryCode { get; set; }
    public int Gold { get; set; }
    public int Silver { get; set; }
    public int Bronze { get; set; }
}

private readonly List<OlympicsData> OlympicsDataSource = new()
{
    new OlympicsData { Country = "USA", CountryCode = "USA", Gold = 40, Silver = 44, Bronze = 42 },
    new OlympicsData { Country = "China", CountryCode = "CHN", Gold = 40, Silver = 27, Bronze = 24 },
    new OlympicsData { Country = "Great Britain", CountryCode = "GBR", Gold = 14, Silver = 22, Bronze = 29 },
    new OlympicsData { Country = "France", CountryCode = "FRA", Gold = 16, Silver = 26, Bronze = 22 },
    new OlympicsData { Country = "Australia", CountryCode = "AUS", Gold = 18, Silver = 19, Bronze = 16 },
    new OlympicsData { Country = "Japan", CountryCode = "JPN", Gold = 20, Silver = 12, Bronze = 13 },
    new OlympicsData { Country = "Italy", CountryCode = "ITA", Gold = 12, Silver = 13, Bronze = 15 },
    new OlympicsData { Country = "Netherlands", CountryCode = "NLD", Gold = 15, Silver = 7,  Bronze = 12 },
    new OlympicsData { Country = "Germany", CountryCode = "DEU", Gold = 12, Silver = 13, Bronze = 8  },
    new OlympicsData { Country = "South Korea", CountryCode = "KOR", Gold = 13, Silver = 9,  Bronze = 10 }
};

Now, populate the categories and chartSeries collections with the appropriate data defining the chart’s categories and series. Then, assign these values to the CategoryFields and SeriesFields properties of the ChartSettings, respectively.

NOTE

The default series type is Line. Use the SeriesType property to change the series type.

RAZOR

<div class="control-section">
    <SfChartWizard>
        <ChartSettings DataSource="@OlympicsDataSource"
                       CategoryFields="@categories"
                       SeriesType="ChartWizardSeriesType.Column"
                       SeriesFields="@chartSeries">
        </ChartSettings>
    </SfChartWizard>
</div>

@code {
    private readonly List<string> chartSeries = new() { "Gold", "Silver", "Bronze" };
    private readonly List<string> categories = new() { "Country", "CountryCode" };

    public class OlympicsData
    {
        public string? Country { get; set; }
        public string? CountryCode { get; set; }
        public int Gold { get; set; }
        public int Silver { get; set; }
        public int Bronze { get; set; }
    }

    private readonly List<OlympicsData> OlympicsDataSource = new()
    {
        new OlympicsData { Country = "USA", CountryCode = "USA", Gold = 40, Silver = 44, Bronze = 42 },
        new OlympicsData { Country = "China", CountryCode = "CHN", Gold = 40, Silver = 27, Bronze = 24 },
        new OlympicsData { Country = "Great Britain", CountryCode = "GBR", Gold = 14, Silver = 22, Bronze = 29 },
        new OlympicsData { Country = "France", CountryCode = "FRA", Gold = 16, Silver = 26, Bronze = 22 },
        new OlympicsData { Country = "Australia", CountryCode = "AUS", Gold = 18, Silver = 19, Bronze = 16 },
        new OlympicsData { Country = "Japan", CountryCode = "JPN", Gold = 20, Silver = 12, Bronze = 13 },
        new OlympicsData { Country = "Italy", CountryCode = "ITA", Gold = 12, Silver = 13, Bronze = 15 },
        new OlympicsData { Country = "Netherlands", CountryCode = "NLD", Gold = 15, Silver = 7,  Bronze = 12 },
        new OlympicsData { Country = "Germany", CountryCode = "DEU", Gold = 12, Silver = 13, Bronze = 8  },
        new OlympicsData { Country = "South Korea", CountryCode = "KOR", Gold = 13, Silver = 9,  Bronze = 10 }
    };
}

Theme

Blazor Chart Wizard has built-in themes that can be used to change the appearance of the chart.

Prerequisites

In order to apply same theme update for the overall Chart Wizard UI, include the same theme stylesheet (this can be accessed from NuGet through Static Web Assets) in the <head> tag in the App.razor file as shown below:

RAZOR

<head>
    ....
    <link href="_content/Syncfusion.Blazor.Themes/material3.css" rel="stylesheet" />
</head>

The Theme property is used to specify the visual theme applied to the chart.

RAZOR

<div class="control-section">
    <SfChartWizard Theme="Theme.Material3">
        <ChartSettings DataSource="@OlympicsDataSource"
                       CategoryFields="@categories"
                       SeriesType="ChartWizardSeriesType.Bar"
                       SeriesFields="@chartSeries">
        </ChartSettings>
    </SfChartWizard>
</div>

@code {
    private readonly List<string> chartSeries = new() { "Gold", "Silver", "Bronze" };
    private readonly List<string> categories = new() { "Country", "CountryCode" };

    public class OlympicsData
    {
        public string? Country { get; set; }
        public string? CountryCode { get; set; }
        public int Gold { get; set; }
        public int Silver { get; set; }
        public int Bronze { get; set; }
    }

    private readonly List<OlympicsData> OlympicsDataSource = new()
    {
        new OlympicsData { Country = "USA", CountryCode = "USA", Gold = 40, Silver = 44, Bronze = 42 },
        new OlympicsData { Country = "China", CountryCode = "CHN", Gold = 40, Silver = 27, Bronze = 24 },
        new OlympicsData { Country = "Great Britain", CountryCode = "GBR", Gold = 14, Silver = 22, Bronze = 29 },
        new OlympicsData { Country = "France", CountryCode = "FRA", Gold = 16, Silver = 26, Bronze = 22 },
        new OlympicsData { Country = "Australia", CountryCode = "AUS", Gold = 18, Silver = 19, Bronze = 16 },
        new OlympicsData { Country = "Japan", CountryCode = "JPN", Gold = 20, Silver = 12, Bronze = 13 },
        new OlympicsData { Country = "Italy", CountryCode = "ITA", Gold = 12, Silver = 13, Bronze = 15 },
        new OlympicsData { Country = "Netherlands", CountryCode = "NLD", Gold = 15, Silver = 7,  Bronze = 12 },
        new OlympicsData { Country = "Germany", CountryCode = "DEU", Gold = 12, Silver = 13, Bronze = 8  },
        new OlympicsData { Country = "South Korea", CountryCode = "KOR", Gold = 13, Silver = 9,  Bronze = 10 }
    };
}
