Getting Started with Blazor 3D Chart Component in Blazor Server App

13 Jun 20247 minutes to read

This section briefly explains about how to include Blazor 3D Chart component in your Blazor Server App using Visual Studio.

Prerequisites

Create a new Blazor App in Visual Studio

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

Install Syncfusion Blazor 3D Chart NuGet in the App

To add Blazor 3D 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.Chart3D. Alternatively, you can utilize the following package manager command to achieve the same.

Install-Package Syncfusion.Blazor.Chart3D -Version 26.1.35

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 namespace.

@using Syncfusion.Blazor
@using Syncfusion.Blazor.Chart3D

Now, register the Syncfusion Blazor Service in the ~/Program.cs file of your Blazor Server 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();
....

Add script resources

The script can be accessed from NuGet through Static Web Assets. Reference the 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.

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

NOTE

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

Add Blazor 3D Chart Component

Add the Syncfusion Blazor 3D Chart component in the ~/Pages/Index.razor file.

<SfChart3D>

</SfChart3D>
  • Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to launch the application. This will render the Syncfusion Blazor 3D Chart component in your default web browser.

Populate Blazor 3D Chart with data

To bind data for the 3D chart component, you can assign a IEnumerable object to the DataSource property. It can also be provided as an instance of the DataManager.

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 }
};

Now, map the data fields Month and Sales 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.

<SfChart3D>
    <Chart3DPrimaryXAxis ValueType="Syncfusion.Blazor.Chart3D.ValueType.Category"></Chart3DPrimaryXAxis>
    <Chart3DSeriesCollection>
        <Chart3DSeries DataSource="@Sales" XName="Month" YName="SalesValue" Type="Chart3DSeriesType.Column">
        </Chart3DSeries>
    </Chart3DSeriesCollection>
</SfChart3D>

@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 }
    };
}

Add 3D Chart title

Using the Title property, you can add a title to the chart and the axes to provide the user with quick information about the data plotted in the chart.

<SfChart3D Title="Sales Analysis">
    <Chart3DPrimaryXAxis Title="Month" ValueType="Syncfusion.Blazor.Chart3D.ValueType.Category"></Chart3DPrimaryXAxis>
    
     <Chart3DPrimaryYAxis Title="Sales in Dollar"><Chart3DPrimaryYAxis>
    <Chart3DSeriesCollection>
        <Chart3DSeries DataSource="@Sales" XName="Month" YName="SalesValue" Type="Chart3DSeriesType.Column">
        </Chart3DSeries>
    </Chart3DSeriesCollection>
</SfChart3D>

Enable legend

You can use legend for the 3D Chart by setting the Visible property to true in Chart3DLegendSettings. The legend name can be changed by using the Name property in the series.

<SfChart3D Title="Sales Analysis">
    <Chart3DPrimaryXAxis ValueType="Syncfusion.Blazor.Chart3D.ValueType.Category"></Chart3DPrimaryXAxis>
    <Chart3DLegendSettings Visible="true"></Chart3DLegendSettings>
    <Chart3DSeriesCollection>
        <Chart3DSeries DataSource="@Sales" Name="Sales" XName="Month" YName="SalesValue" Type="Chart3DSeriesType.Column">
        </Chart3DSeries>
    </Chart3DSeriesCollection>
</SfChart3D>

Add data label

You can add data labels to improve the readability of the 3D Chart. This can be achieved by setting the Visible property to true in the Chart3DDataLabel. Now, the data labels are arranged smartly based on series.

<SfChart3D Title="Sales Analysis">
    <Chart3DPrimaryXAxis ValueType="Syncfusion.Blazor.Chart3D.ValueType.Category"></Chart3DPrimaryXAxis>
    <Chart3DSeriesCollection>
        <Chart3DSeries DataSource="@Sales" XName="Month" YName="SalesValue" Type="Chart3DSeriesType.Column">
            <Chart3DDataLabel Visible="true"></Chart3DDataLabel>
        </Chart3DSeries>
    </Chart3DSeriesCollection>
</SfChart3D>

Enable tooltip

The tooltip is useful when you cannot display information by using the data labels due to space constraints. You can enable tooltip by setting the Enable property in Chart3DTooltipSettings to true.

<SfChart3D Title="Sales Analysis">
    <Chart3DPrimaryXAxis Title="Month" ValueType="Syncfusion.Blazor.Chart3D.ValueType.Category"></Chart3DPrimaryXAxis>
    <Chart3DPrimaryYAxis Title="Sales in Dollar"></Chart3DPrimaryYAxis>
    <Chart3DTooltipSettings Enable="true"></Chart3DTooltipSettings>
    <Chart3DSeriesCollection>
        <Chart3DSeries DataSource="@Sales" XName="Month" YName="SalesValue" Type="Chart3DSeriesType.Column">
        </Chart3DSeries>
    </Chart3DSeriesCollection>
</SfChart3D>
