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

.NET CLI
dotnet new blazor -o BlazorApp -int Auto
cd BlazorApp
cd BlazorApp.Client

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

Install Syncfusion^® Blazor StockChart and Themes NuGet in the App

Here’s an example of how to add Blazor Stock Chart component in the application using the following command in the command prompt (Windows) or terminal (Linux and macOS) to install a Syncfusion.Blazor.StockChart and Syncfusion.Blazor.Themes NuGet package. See Install and manage packages using the dotnet CLI topics for more details.

If using the WebAssembly or Auto render modes in the Blazor Web App, install Syncfusion^® Blazor component NuGet packages in the client project.

.NET CLI
dotnet add package Syncfusion.Blazor.StockChart --version 32.1.19
dotnet add package Syncfusion.Blazor.Themes --version 32.1.19
dotnet restore

NOTE

Syncfusion^® Blazor components are available in nuget.org. Refer to the NuGet packages topic for the available NuGet packages list with component details.

Add Import Namespaces

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

~/_Imports.razor
@using Syncfusion.Blazor
@using Syncfusion.Blazor.Charts

Register Syncfusion^® Blazor Service

If the Interactive Render Mode is set to WebAssembly or Auto, register the Syncfusion^® Blazor service in the ~/Program.cs files of the main server project and associated .Client project.

Server(~/_Program.cs)
Client(~/_Program.cs)
...
...
using Syncfusion.Blazor;

var builder = WebApplication.CreateBuilder(args);

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

var app = builder.Build();
....
...
using Syncfusion.Blazor;

var builder = WebAssemblyHostBuilder.CreateDefault(args);
builder.Services.AddSyncfusionBlazor();

await builder.Build().RunAsync();

Add stylesheet and script resources

The theme stylesheet and script can be accessed from NuGet through Static Web Assets. Include the stylesheet reference in the <head> section and the script reference at the end of the <body> in the ~/Components/App.razor file as shown below:

<head>
    ....
    <link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
</head>

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

NOTE

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

Add Syncfusion^® Blazor Stock Chart component

Add the Syncfusion^® Blazor Stock Chart component to a Razor page located under the Pages folder (e.g., Pages/Home.razor) in either the Server or Client project. If an interactivity location as Per page/component in the web app, define a render mode at top of the component, as follows:

Interactivity location	RenderMode	Code
Per page/component	Auto	@rendermode InteractiveAuto
	WebAssembly	@rendermode InteractiveWebAssembly
	None	—

NOTE

If an Interactivity Location is set to Global and the Render Mode is set to Auto or WebAssembly, the render mode is configured in the App.razor file by default.

RAZOR

@* desired render mode define here *@
@rendermode InteractiveAuto

Populate Blazor Stock Chart with Data

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

RAZOR

@code{
    public class StockChartData
    {
        public DateTime Date { get; set; }
        public Double Open { get; set; }
        public Double Low { get; set; }
        public Double Close { get; set; }
        public Double High { get; set; }
        public Double Volume { get; set; }
    }

    public List<StockChartData> StockDetails = new List<StockChartData>
    {
        new StockChartData { Date = new DateTime(2012, 04, 02), Open = 85.9757, High = 90.6657, Low = 85.7685, Close = 90.5257, Volume = 660187068},
        new StockChartData { Date = new DateTime(2012, 04, 09), Open = 89.4471, High = 92, Low = 86.2157, Close = 86.4614, Volume = 912634864},
        new StockChartData { Date = new DateTime(2012, 04, 16), Open = 87.1514, High = 88.6071, Low = 81.4885, Close = 81.8543, Volume = 1221746066},
        new StockChartData { Date = new DateTime(2012, 04, 23), Open = 81.5157, High = 88.2857, Low = 79.2857, Close = 86.1428, Volume = 965935749},
        new StockChartData { Date = new DateTime(2012, 04, 30), Open = 85.4, High =  85.4857, Low = 80.7385, Close = 80.75, Volume = 615249365},
        new StockChartData { Date = new DateTime(2012, 05, 07), Open = 80.2143, High = 82.2685, Low = 79.8185, Close = 80.9585, Volume = 541742692},
        new StockChartData { Date = new DateTime(2012, 05, 14), Open = 80.3671, High = 81.0728, Low = 74.5971, Close = 75.7685, Volume = 708126233},
        new StockChartData { Date = new DateTime(2012, 05, 21), Open = 76.3571, High = 82.3571, Low = 76.2928, Close = 80.3271, Volume = 682076215},
        new StockChartData { Date = new DateTime(2012, 05, 28), Open = 81.5571, High = 83.0714, Low = 80.0743, Close = 80.1414, Volume = 480059584},
    };
}

Now set the StockDetails to DataSource property. By default, Stock Chart will be rendered based on the provided Date and High fields value from datasource without any mapping.

RAZOR
<SfStockChart>
    <StockChartSeriesCollection>
        <StockChartSeries DataSource="@StockDetails" Type="ChartSeriesType.Candle" XName="Date" YName="Close" High="High" Low="Low" Open="Open" Close="Close" Volume="Volume"></StockChartSeries>
    </StockChartSeriesCollection>
</SfStockChart>

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

Adding Title

A title using Title property can be added in the Stock Chart, to provide quick information to the user about the data plotted in the component.

RAZOR
<SfStockChart Title="AAPL Historical">
    <StockChartSeriesCollection>
        <StockChartSeries DataSource="@StockDetails" Type="ChartSeriesType.Candle" XName="Date" YName="Close" High="High" Low="Low" Open="Open" Close="Close" Volume="Volume"></StockChartSeries>
    </StockChartSeriesCollection>
</SfStockChart>

@code {
    public class ChartData
    {
        public DateTime Date { get; set; }
        public Double Open { get; set; }
        public Double Low { get; set; }
        public Double Close { get; set; }
        public Double High { get; set; }
        public Double Volume { get; set; }
    }

    public List<ChartData> StockDetails = new List<ChartData>
    {
        new ChartData { Date = new DateTime(2012, 04, 02), Open= 85.9757, High = 90.6657,Low = 85.7685, Close = 90.5257,Volume = 660187068},
        new ChartData { Date = new DateTime(2012, 04, 09), Open= 89.4471, High = 92,Low = 86.2157, Close = 86.4614,Volume = 912634864},
        new ChartData { Date = new DateTime(2012, 04, 16), Open= 87.1514, High = 88.6071,Low = 81.4885, Close = 81.8543,Volume = 1221746066},
        new ChartData { Date = new DateTime(2012, 04, 23), Open= 81.5157, High = 88.2857,Low = 79.2857, Close = 86.1428,Volume = 965935749},
        new ChartData { Date = new DateTime(2012, 04, 30), Open= 85.4, High =  85.4857,Low = 80.7385, Close = 80.75,Volume = 615249365},
        new ChartData { Date = new DateTime(2012, 05, 07), Open= 80.2143, High = 82.2685,Low = 79.8185, Close = 80.9585,Volume = 541742692},
        new ChartData { Date = new DateTime(2012, 05, 14), Open= 80.3671, High = 81.0728,Low = 74.5971, Close = 75.7685,Volume = 708126233},
        new ChartData { Date = new DateTime(2012, 05, 21), Open= 76.3571, High = 82.3571,Low = 76.2928, Close = 80.3271,Volume = 682076215},
        new ChartData { Date = new DateTime(2012, 05, 28), Open= 81.5571, High = 83.0714,Low = 80.0743, Close = 80.1414,Volume = 480059584}
   };
}

Adding Crosshair

The crosshair is a vertical and horizontal line on the view that shows the value of an axis when the mouse or touch is in a certain position. The crosshair lines can be enabled by using Enable property in the StockChartCrosshairSettings. Likewise tooltip label for an axis can be enabled by using Enable property in the StockChartTooltipSettings.

RAZOR
<SfStockChart>
    <StockChartCrosshairSettings Enable="true"></StockChartCrosshairSettings>
    <StockChartSeriesCollection>
        <StockChartSeries DataSource="@StockDetails" Type="ChartSeriesType.Column" XName="Date" YName="Y"></StockChartSeries>
    </StockChartSeriesCollection>
</SfStockChart>

@code {
    public class ChartData
    {
        public DateTime Date { get; set; }
        public Double Y { get; set; }
    }

    public List<ChartData> StockDetails = new List<ChartData>
    {
         new ChartData { Date = new DateTime(2012, 04, 02), Y= 100},
         new ChartData { Date = new DateTime(2012, 04, 09), Y= 10 },
         new ChartData { Date = new DateTime(2012, 04, 16), Y= 500},
         new ChartData { Date = new DateTime(2012, 04, 23), Y= 80 },
         new ChartData { Date = new DateTime(2012, 04, 30), Y= 200},
         new ChartData { Date = new DateTime(2012, 05, 07), Y= 600},
         new ChartData { Date = new DateTime(2012, 05, 14), Y= 50 },
         new ChartData { Date = new DateTime(2012, 05, 21), Y= 700},
         new ChartData { Date = new DateTime(2012, 05, 28), Y= 90 }
   };
}

Adding Trackball

The trackball is used to track a closest data point to the mouse or touch position. The trackball marker indicates the closest point and trackball tooltip displays the information about the point. It can be enabled by setting the Enable property in the StockChartCrosshairSettings to true and Shared property in the StockChartTooltipSettings to true in component.

RAZOR
<SfStockChart>
    <StockChartCrosshairSettings Enable="true" LineType="LineType.Vertical"></StockChartCrosshairSettings>
    <StockChartTooltipSettings Enable="true" Shared="true" Format="${point.x} : ${point.y}" Header="AAPL"></StockChartTooltipSettings>
    <StockChartSeriesCollection>
        <StockChartSeries DataSource="@StockDetails" Type="ChartSeriesType.Line" XName="Date" YName="Y"></StockChartSeries>
        <StockChartSeries DataSource="@StockDetails" Type="ChartSeriesType.Line" XName="Date" YName="Y1"></StockChartSeries>
    </StockChartSeriesCollection>
</SfStockChart>

@code {
    public class ChartData
    {
        public DateTime Date { get; set; }
        public Double Y { get; set; }
        public Double Y1 { get; set; }
    }

    public List<ChartData> StockDetails = new List<ChartData>
    {
         new ChartData { Date = new DateTime(2012, 04, 02), Y= 100, Y1= 50},
         new ChartData { Date = new DateTime(2012, 04, 09), Y= 10 , Y1= 5},
         new ChartData { Date = new DateTime(2012, 04, 16), Y= 500, Y1= 250},
         new ChartData { Date = new DateTime(2012, 04, 23), Y= 80 , Y1= 60},
         new ChartData { Date = new DateTime(2012, 04, 30), Y= 200, Y1= 100},
         new ChartData { Date = new DateTime(2012, 05, 07), Y= 600, Y1= 300},
         new ChartData { Date = new DateTime(2012, 05, 14), Y= 50 , Y1= 25},
         new ChartData { Date = new DateTime(2012, 05, 21), Y= 700, Y1= 350},
         new ChartData { Date = new DateTime(2012, 05, 28), Y= 90 , Y1= 45}
   };
