Getting Started with Blazor Stock Chart in Blazor Web App

27 Apr 202615 minutes to read

This section briefly explains about how to include Syncfusion® Blazor Stock Chart component in your Blazor Web App using Visual Studio, Visual Studio Code, and the .NET CLI.

Prerequisites

Create a new Blazor Web App in Visual Studio

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

Prerequisites

Create a new Blazor Web App in Visual Studio Code

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

For example, in a Blazor Web App with the Auto interactive render mode, use the following commands in the integrated terminal (Ctrl+`):

dotnet new blazor -o BlazorWebApp -int Auto
cd BlazorWebApp
cd BlazorWebApp.Client

Prerequisites

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

dotnet --version

Create a Blazor Web App using .NET CLI

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

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

dotnet new blazor -o BlazorWebApp -int Auto
cd BlazorWebApp
cd BlazorWebApp.Client

NOTE

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

Install Syncfusion® Blazor packages

Install Syncfusion.Blazor.StockChart and Syncfusion.Blazor.Themes NuGet packages 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 commands in the Package Manager Console to achieve the same.

Install-Package Syncfusion.Blazor.StockChart -Version 33.2.3
Install-Package Syncfusion.Blazor.Themes -Version 33.2.3

If using the WebAssembly or Auto render modes in the Blazor Web App, install these packages in the client project.

NOTE

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

Add import namespaces

After the packages are installed, open the ~/_Imports.razor file in the client project and import the Syncfusion.Blazor and Syncfusion.Blazor.Charts namespaces.

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

Register Syncfusion® Blazor service

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

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

NOTE

If the Interactive Render Mode is set to WebAssembly or Auto, register the Syncfusion® Blazor service in Program.cs files of both the server and client projects in your Blazor Web App.

Add stylesheet and script resources

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

<link href="_content/Syncfusion.Blazor.Themes/fluent2.css" rel="stylesheet" />
....
<script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>

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 in the ~/Components/Pages/*.razor file. If the interactivity location is set to Per page/component in the Web App, define a render mode at the top of the ~/Pages/*.razor file. (For example, InteractiveServer, InteractiveWebAssembly or InteractiveAuto).

NOTE

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

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

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.

@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.

@using Syncfusion.Blazor.Charts

<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.

@using Syncfusion.Blazor.Charts

<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.

@using Syncfusion.Blazor.Charts

<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.

@using Syncfusion.Blazor.Charts

<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}
   };
}
