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).

.NET CLI
dotnet --version

Create a Blazor Server App using .NET CLI

dotnet restore

NOTE

Add Import Namespaces

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

~/_Imports.razor

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

Register Syncfusion^® Blazor Service

~/Program.cs
....
....
using Syncfusion.Blazor;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
....
....
builder.Services.AddSyncfusionBlazor();

....

Add script resources

The script can be accessed from NuGet through Static Web Assets. Include script reference at the end of the <body> in the App.razor file as shown below:

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

    //Blazor Chart Component script reference.
    <!-- <script src="_content/Syncfusion.Blazor.Charts/scripts/sf-chart.min.js" type="text/javascript"></script> -->
</body>

NOTE

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

Add Blazor Chart Component

Add the Syncfusion^® Blazor 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 Home.razor page.

RAZOR

<SfChart>

</SfChart>

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

Populate Blazor chart with data

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

RAZOR

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.

RAZOR
<SfChart>
    <ChartPrimaryXAxis ValueType="Syncfusion.Blazor.Charts.ValueType.Category"></ChartPrimaryXAxis>
    <ChartSeriesCollection>
        <ChartSeries DataSource="@Sales" XName="Month" YName="SalesValue" Type="ChartSeriesType.Column">
        </ChartSeries>
    </ChartSeriesCollection>
</SfChart>

@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 titles

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.

RAZOR
<SfChart Title="Sales Analysis">
    <ChartPrimaryXAxis Title="Month" ValueType="Syncfusion.Blazor.Charts.ValueType.Category"></ChartPrimaryXAxis>
    <ChartPrimaryYAxis Title="Sales in Dollar"></ChartPrimaryYAxis>
    <ChartSeriesCollection>
        <ChartSeries DataSource="@Sales" XName="Month" YName="SalesValue" Type="ChartSeriesType.Column">
        </ChartSeries>
    </ChartSeriesCollection>
</SfChart>

Add data label

You can add data labels to improve the readability of the chart. This can be achieved by setting the Visible property to true in the ChartDataLabel.

RAZOR
<SfChart Title="Sales Analysis">
    <ChartPrimaryXAxis Title="Month" ValueType="Syncfusion.Blazor.Charts.ValueType.Category"></ChartPrimaryXAxis>
    <ChartPrimaryYAxis Title="Sales in Dollar"></ChartPrimaryYAxis>
    <ChartSeriesCollection>
        <ChartSeries DataSource="@Sales" XName="Month" YName="SalesValue" Type="ChartSeriesType.Column">
            <ChartMarker>
                <ChartDataLabel Visible="true"></ChartDataLabel>
            </ChartMarker>
        </ChartSeries>
    </ChartSeriesCollection>
</SfChart>

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

RAZOR
<SfChart Title="Sales Analysis">
    <ChartPrimaryXAxis Title="Month" ValueType="Syncfusion.Blazor.Charts.ValueType.Category"></ChartPrimaryXAxis>
    <ChartPrimaryYAxis Title="Sales in Dollar"></ChartPrimaryYAxis>
    <ChartTooltipSettings Enable="true"></ChartTooltipSettings>
    <ChartSeriesCollection>
        <ChartSeries DataSource="@Sales" XName="Month" YName="SalesValue" Type="ChartSeriesType.Column">
        </ChartSeries>
    </ChartSeriesCollection>
</SfChart>

Enable legend

You can use legend for the chart by setting the Visible property to true in ChartLegendSettings. The legend name can be changed by using the Name property in the series.

RAZOR
<SfChart Title="Sales Analysis">
    <ChartPrimaryXAxis Title="Month" ValueType="Syncfusion.Blazor.Charts.ValueType.Category"></ChartPrimaryXAxis>
    <ChartPrimaryYAxis Title="Sales in Dollar"></ChartPrimaryYAxis>
    <ChartLegendSettings Visible="true"></ChartLegendSettings>
    <ChartSeriesCollection>
        <ChartSeries DataSource="@Sales" Name="Sales" XName="Month" YName="SalesValue" Type="ChartSeriesType.Column">
        </ChartSeries>
    </ChartSeriesCollection>
</SfChart>
