18 Nov 20187 minutes to read

This section briefly explains about how to include Blazor Bullet Chart component in a Blazor Server App using Visual Studio, Visual Studio Code, and the .NET CLI.

Prerequisites

Create a new Blazor App in Visual Studio

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

Prerequisites

Create a new Blazor App in Visual Studio Code

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

Alternatively, create a Server application by using the following command in the integrated terminal(Ctrl+`).

dotnet new blazor -o BlazorApp -int Server
cd BlazorApp

Prerequisites

Install the latest version of .NET SDK. If the .NET SDK is already installed, determine the installed version by running the following command in a command prompt (Windows), terminal (macOS), or command shell (Linux).

dotnet --version

Create a Blazor Server App using .NET CLI

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

dotnet new blazor -o BlazorApp -int Server
cd BlazorApp

NOTE

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

Install required Blazor packages

Install Syncfusion.Blazor.BulletChart NuGet package 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 command in the Package Manager Console to achieve the same.

Install-Package Syncfusion.Blazor.BulletChart -Version 34.1.29

NOTE

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

Add import namespaces

After the package is installed, open the ~/_Imports.razor file and import the Syncfusion.Blazor and Syncfusion.Blazor.Charts namespaces.

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

Register Blazor service

Register the Blazor service in the Program.cs file of your Blazor Server App.

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

Add script resources

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

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

NOTE

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

Add Blazor Bullet Chart component

Add the Blazor Bullet Chart component in the ~/Components/Pages/Home.razor file. If the interactivity location is set to Per page/component, define a render mode at the top of the ~Pages/Home.razor file.

NOTE

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

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

<SfBulletChart DataSource="@BulletChartData" ValueField="FieldValue" TargetField="TargetValue" Minimum="0" Maximum="300" Interval="50">
</SfBulletChart>

@code{
    public class ChartData
    {
        public double FieldValue { get; set; }
        public double TargetValue { get; set; }
    }
    public List<ChartData> BulletChartData = new List<ChartData>
    {
        new ChartData { FieldValue = 270, TargetValue = 250 }
    };
}
  • Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to launch the application. This will render the Blazor Bullet Chart component in the default web browser.

Adding title

Add a title by using the Title property in the Bullet Chart to provide quick information to the user about the data plotted in the component.

<SfBulletChart DataSource="@BulletChartData" ValueField="FieldValue" TargetField="TargetValue" Minimum="0" Maximum="300" Interval="50" Title="Revenue">
</SfBulletChart>

Adding ranges

Add ranges by using the BulletChartRangeCollection to measure the qualitative state by observing the distance between each range.

<SfBulletChart DataSource="@BulletChartData" ValueField="FieldValue" TargetField="TargetValue" Minimum="
0" Maximum="300" Interval="50" Title="Revenue">
    <BulletChartRangeCollection>
        <BulletChartRange End=150> </BulletChartRange>
        <BulletChartRange End=250></BulletChartRange>
        <BulletChartRange End=300></BulletChartRange>
    </BulletChartRangeCollection>
</SfBulletChart>

Use the tooltip to show the measured values by setting the Enable property to true in the BulletChartTooltip.

<SfBulletChart DataSource="@BulletChartData" ValueField="FieldValue" TargetField="TargetValue" Minimum="0" Maximum="300" Interval="50" Title="Revenue">
    <BulletChartTooltip TValue="ChartData" Enable="true"></BulletChartTooltip>
    <BulletChartRangeCollection>
        <BulletChartRange End=150> </BulletChartRange>
        <BulletChartRange End=250></BulletChartRange>
        <BulletChartRange End=300></BulletChartRange>
    </BulletChartRangeCollection>
</SfBulletChart>
