29 Jan 20248 minutes to read

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

Prerequisites

System requirements for Blazor components

Create a new Blazor App in Visual Studio

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

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

Package Manager
Install-Package Syncfusion.Blazor.Charts -Version 26.2.4
Install-Package Syncfusion.Blazor.Themes -Version 26.2.4

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 namespace.

~/_Imports.razor

@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.

Blazor Server App
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 stylesheet and script resources

The theme stylesheet and script can be accessed from NuGet through Static Web Assets. Reference the stylesheet and 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>
    ....
    <link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
    <script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>
</head>

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 Blazor Accumulation Chart component

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

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 },
     };
}

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

Add title

Using the Title property, a title to the accumulation chart is added to provide the user with quick information about the data plotted in the chart.

RAZOR
<SfAccumulationChart Title="Olympic Medal Details">
    <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 },
     };
}

Adding Title in Blazor Accumulation Chart

Add data label

The data labels are added to improve the readability of the accumulation chart. This can be achieved by setting the Visible property to true in the AccumulationDataLabelSettings.

RAZOR
<SfAccumulationChart Title="Olympic Medal Details">
    <AccumulationChartSeriesCollection>
        <AccumulationChartSeries DataSource="@MedalDetails" XName="Country" YName="Medals">
            <AccumulationDataLabelSettings Visible="true"/>
        </AccumulationChartSeries>
    </AccumulationChartSeriesCollection>
</SfAccumulationChart>

Adding Data Label in Blazor Accumulation Chart

When space constraints prevent from displaying the information using data labels, the tooltip comes in handy. The tooltip can be enabled by setting the Enable property in AccumulationChartTooltipSettings to true.

RAZOR
<SfAccumulationChart Title="Olympic Medal Details">
    <AccumulationChartSeriesCollection>
        <AccumulationChartSeries DataSource="@MedalDetails" XName="Country" YName="Medals">
        </AccumulationChartSeries>
    </AccumulationChartSeriesCollection>
    <AccumulationChartTooltipSettings Enable="true"></AccumulationChartTooltipSettings>
</SfAccumulationChart>

Blazor Accumulation Chart displays Tooltip

Enable Legend

Legend is used for the accumulation chart by setting the Visible property to true in the AccumulationChartLegendSettings.

RAZOR
<SfAccumulationChart Title="Olympic Medal Details">
    <AccumulationChartSeriesCollection>
        <AccumulationChartSeries DataSource="@MedalDetails" XName="Country" YName="Medals">
            <AccumulationDataLabelSettings Visible="true"></AccumulationDataLabelSettings>
        </AccumulationChartSeries>
    </AccumulationChartSeriesCollection>
    <AccumulationChartTooltipSettings Enable="true"></AccumulationChartTooltipSettings>
    <AccumulationChartLegendSettings Visible="true"></AccumulationChartLegendSettings>
</SfAccumulationChart>
