Getting started with Blazor Bullet Chart component

This section briefly explains about how to include a Bullet Chart in your Blazor server-side application. You can refer Getting Started with Syncfusion Blazor for Server-Side in Visual Studio 2019 page for the introduction and configuring the common specifications.

Importing Syncfusion Blazor component in the application

  1. Install Syncfusion.Blazor NuGet package to the application by using the NuGet Package Manager. Please ensure to check the Include prerelease option.
  2. You can add the client-side style resources through CDN or from NuGet package in the HEAD element of the ~/Pages/_Host.cshtml page.
<head>
    <link href="_content/Syncfusion.Blazor/styles/bootstrap4.css" rel="stylesheet" />
</head>

Note: The same theme file can be referred through the CDN version by using https://cdn.syncfusion.com/blazor/18.1.36-beta/styles/bootstrap4.css

For Internet Explorer 11 kindly refer the polyfills. Refer the documentation for more information.

<head>
    <link href="_content/Syncfusion.Blazor/styles/bootstrap4.css" rel="stylesheet" />
    <script src="https://github.com/Daddoon/Blazor.Polyfill/releases/download/3.0.1/blazor.polyfill.min.js"></script>
</head>

Adding component package to the application

Open **~/_Imports.razor file and import the Syncfusion.Blazor.**

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

Add SyncfusionBlazor service in Startup.cs

Open the Startup.cs file and add services required by Syncfusion components using service.AddSyncfusionBlazor() method. Add this method in the ConfigureServices function as follows.

using Syncfusion.Blazor;
namespace BlazorApplication
{
    public class Startup
    {
        ....
        ....
        public void ConfigureServices(IServiceCollection services)
        {
            ....
            ....
            services.AddSyncfusionBlazor();
        }
    }
}

Note: To enable custom client side resource loading from CRG or CDN. You need to disable resource loading by AddSyncfusionBlazor(true) and load the scripts in the HEAD element of the ~/Pages/_Host.cshtml page.

<head>
    <script src="https://cdn.syncfusion.com/blazor/18.1.36-beta/dist/syncfusion-blazor.min.js"></script>
</head>

Adding Bullet Chart component to the application

Now, add the Syncfusion Blazor components in any web page (razor) in the Pages folder. For example, the BulletChart component is added in the ~/Pages/Index.razor page.

  @using Syncfusion.Blazor.Charts

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

@code{
    public class ChartData
    {
        public double value { get; set; }
        public double target { get; set; }
    }
    public List<ChartData> BulletChartData = new List<ChartData>
{
        new ChartData { value = 270, target = 250 }
    };
}

Run the application

After successful compilation of your application, the Syncfusion Blazor Bullet Chart component will render in the web browser.

Bullet Chart

Add Title

You can add a title using Title property to the Bullet Chart, to provide quick information to the user about the data plotted in the chart.

@using Syncfusion.Blazor.Charts

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

@code{
    public class ChartData
    {
        public double value { get; set; }
        public double target { get; set; }
    }
    public List<ChartData> BulletChartData = new List<ChartData>
{
        new ChartData { value = 270, target = 250 }
    };
}

Bullet Chart

@using Syncfusion.Blazor.Charts

    <BulletChartRangeCollection>
        <BulletChartRange End=150> </BulletChartRange>
        <BulletChartRange End=250></BulletChartRange>
        <BulletChartRange End=300></BulletChartRange>
    </BulletChartRangeCollection>
</SfBulletChart>

@code{
    public class ChartData
    {
        public double value { get; set; }
        public double target { get; set; }
    }
    public List<ChartData> BulletChartData = new List<ChartData>
{
        new ChartData { value = 270, target = 250 }
    };
}

@using Syncfusion.Blazor.Charts

    <BulletChartTooltip Enable="true"></BulletChartTooltip>
    <BulletChartRangeCollection>
        <BulletChartRange End=150> </BulletChartRange>
        <BulletChartRange End=250></BulletChartRange>
        <BulletChartRange End=300></BulletChartRange>
    </BulletChartRangeCollection>
</SfBulletChart>

@code{
    public class ChartData
    {
        public double value { get; set; }
        public double target { get; set; }
    }
    public List<ChartData> BulletChartData = new List<ChartData>
