Getting Started with Blazor Accumulation Chart in Blazor Web App

27 Apr 202610 minutes to read

This section briefly explains about how to include Syncfusion® Blazor Accumulation Chart component in your Blazor Web App using Visual Studio, Visual Studio Code, and the .NET CLI.

Prerequisites

Create a new Blazor Web App in Visual Studio

Create a Blazor Web App using Visual Studio via Microsoft Templates or the Syncfusion® Blazor Extension. For detailed instructions, refer to the Blazor Web App Getting Started documentation.

Prerequisites

Create a new Blazor Web App in Visual Studio Code

Create a Blazor Web App using Visual Studio Code via Microsoft Templates or the Syncfusion® Blazor Extension. For detailed instructions, refer to the Blazor Web App Getting Started documentation.

For example, in a Blazor Web App with the Auto interactive render mode, use the following commands in the integrated terminal (Ctrl+`).

dotnet new blazor -o BlazorWebApp -int Auto
cd BlazorWebApp
cd BlazorWebApp.Client

Prerequisites

Install the latest version of .NET SDK. If you previously installed the SDK, you can determine the installed version by executing the following command in a command prompt (Windows) or terminal (macOS) or command shell (Linux).

dotnet --version

Create a Blazor Web App using .NET CLI

Run the following command to create a new Blazor Web App in a command prompt (Windows) or terminal (macOS) or command shell (Linux). For detailed instructions, refer to the Blazor Web App Getting Started documentation.

For example, in a Blazor Web App with the Auto interactive render mode, use the following commands:

dotnet new blazor -o BlazorWebApp -int Auto
cd BlazorWebApp
cd BlazorWebApp.Client

This command creates a new Blazor Web App and places it in a new directory called BlazorWebApp inside your current location. See the Create a Blazor App and dotnet new CLI command topics for more details.

NOTE

Configure the appropriate Interactive render mode and Interactivity location while creating a Blazor Web App. For detailed information, refer to the interactive render mode documentation.

Install Syncfusion® Blazor packages

Install Syncfusion.Blazor.Charts and Syncfusion.Blazor.Themes NuGet packages in your project using the NuGet Package Manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), or the integrated terminal in Visual Studio Code (dotnet add package), or the .NET CLI.

Alternatively, run the following commands in the Package Manager Console to achieve the same.

Install-Package Syncfusion.Blazor.Charts -Version 33.2.3
Install-Package Syncfusion.Blazor.Themes -Version 33.2.3

If using the WebAssembly or Auto render modes in the Blazor Web App, install these packages in the client project.

NOTE

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

Add import namespaces

After the packages are installed, open the ~/_Imports.razor file in the client project and import the Syncfusion.Blazor and Syncfusion.Blazor.Charts namespaces.

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

Register Syncfusion® Blazor service

Register the Syncfusion® Blazor service in the Program.cs file of your Blazor Web App.

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

NOTE

If the Interactive Render Mode is set to WebAssembly or Auto, register the Syncfusion® Blazor service in Program.cs files of both the server and client projects in your Blazor Web App.

Add stylesheet and script resources

The theme stylesheet and script can be accessed from NuGet through Static Web Assets. Include the stylesheet and script references in the ~/Components/App.razor file.

<link href="_content/Syncfusion.Blazor.Themes/fluent2.css" rel="stylesheet" />
....
<script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>

NOTE

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

Add Syncfusion® Blazor Accumulation Chart component

Add the Syncfusion® Blazor Accumulation Chart component in the ~/Components/Pages/*.razor file. If the interactivity location is set to Per page/component in the Web App, define a render mode at the top of the ~Pages/*.razor file. (For example, InteractiveServer, InteractiveWebAssembly or InteractiveAuto).

NOTE

If the Interactivity Location is set to Global with Auto or WebAssembly, the render mode is automatically configured in the App.razor file by default.

@* desired render mode define here *@
@rendermode InteractiveAuto
@using Syncfusion.Blazor.Charts

<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 the 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.

@using Syncfusion.Blazor.Charts

<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.

<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

Enable Tooltip

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.

<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.

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