This section briefly explains about how to include Blazor Accumulation Chart component in your Blazor Web App using Visual Studio.

Prerequisites

System requirements for Blazor components

Create a new Blazor Web App

You can create a Blazor Web App using Visual Studio 2022 via Microsoft Templates or the Syncfusion Blazor Extension.

You need to configure the corresponding Interactive render mode and Interactivity location while creating a Blazor Web Application.

Install Syncfusion Blazor Charts and Themes NuGet in the App

To add Blazor Accumulation 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.Charts and Syncfusion.Blazor.Themes.

If you utilize WebAssembly or Auto render modes in the Blazor Web App need to be install Syncfusion Blazor components NuGet packages within the client project.

Alternatively, you can utilize the following package manager command to achieve the same.

Package Manager
Install-Package Syncfusion.Blazor.Charts -Version 25.1.35
Install-Package Syncfusion.Blazor.Themes -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 .

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

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

If you select an Interactive render mode as WebAssembly or Auto, you need to register the Syncfusion Blazor service in both ~/Program.cs files of your Blazor Web App.

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

Add stylesheet and script resources

The theme stylesheet and script can be accessed from NuGet through Static Web Assets. Include the stylesheet reference in the <head> section and the script reference at the end of the <body> in the ~/Components/App.razor file as shown below:

<head>
    ....
    <link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
</head>
....
<body>
    ....
    <script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>
</body>

NOTE

Check out the Blazor Themes topic to discover various methods (Static Web Assets, CDN, and CRG) for referencing themes in your Blazor application. Also, check out the Adding Script Reference topic to learn different approaches for adding script references in your Blazor application.

Add Syncfusion Blazor Accumulation Chart component

Add the Syncfusion Blazor Accumulation Chart component in the ~Pages/.razor file. If an interactivity location as Per page/component in the web app, define a render mode at the top of the ~Pages/.razor component, as follows:

RAZOR

@* desired render mode define here *@
@rendermode InteractiveAuto

RAZOR
<SfAccumulationChart>
    <AccumulationChartSeriesCollection>
        <AccumulationChartSeries DataSource="@MedalDetails" XName="Country" YName="Medals">
        </AccumulationChartSeries>
    </AccumulationChartSeriesCollection>
</SfAccumulationChart>

@code{
    public class ChartData
    {
        public string Country { get; set;}
        public double Medals { get; set;}
    }

    public List<ChartData> MedalDetails = new List<ChartData>
    {
        new ChartData { Country= "United States of America", Medals= 46 },
        new ChartData { Country= "Great Britain", Medals= 27 },
        new ChartData { Country= "China", Medals= 26 },
        new ChartData { Country= "United Kingdom", Medals= 23 },
        new ChartData { Country= "Australia", Medals= 16 },
        new ChartData { Country= "India", Medals= 36 },
        new ChartData { Country= "Nigeria", Medals= 12 },
        new ChartData { Country= "Brazil", Medals= 20 },
     };
}

    <AccumulationChartSeriesCollection>
        <AccumulationChartSeries DataSource="@MedalDetails" XName="Country" YName="Medals">
        </AccumulationChartSeries>
    </AccumulationChartSeriesCollection>
</SfAccumulationChart>
@code{
    public class ChartData
    {
        public string Country { get; set; }
        public double Medals { get; set; }
    }

    public List<ChartData> MedalDetails = new List<ChartData>
    {
        new ChartData { Country= "United States of America", Medals= 46 },
        new ChartData { Country= "Great Britain", Medals= 27 },
        new ChartData { Country= "China", Medals= 26 },
        new ChartData { Country= "United Kingdom", Medals= 23 },
        new ChartData { Country= "Australia", Medals= 16 },
        new ChartData { Country= "India", Medals= 36 },
        new ChartData { Country= "Nigeria", Medals= 12 },

     };
}

Adding Title in Blazor Accumulation Chart

RAZOR
<SfAccumulationChart Title="Olympic Medal Details">

        <AccumulationChartSeries DataSource="@MedalDetails" XName="Country" YName="Medals">
            <AccumulationDataLabelSettings Visible="true"/>
        </AccumulationChartSeries>
    </AccumulationChartSeriesCollection>
</SfAccumulationChart>

Adding Data Label in Blazor Accumulation Chart

    <AccumulationChartSeriesCollection>
        <AccumulationChartSeries DataSource="@MedalDetails" XName="Country" YName="Medals">
        </AccumulationChartSeries>
    </AccumulationChartSeriesCollection>
    <AccumulationChartTooltipSettings Enable="true"></AccumulationChartTooltipSettings>
</SfAccumulationChart>

            <AccumulationDataLabelSettings Visible="true"></AccumulationDataLabelSettings>
        </AccumulationChartSeries>
    </AccumulationChartSeriesCollection>
    <AccumulationChartTooltipSettings Enable="true"></AccumulationChartTooltipSettings>
