29 Nov 202413 minutes to read
This section briefly explains about how to include Blazor Stock Chart component in your Blazor Server App and Blazor WebAssembly App using Visual Studio.
To get start quickly with Blazor Stock Chart component, check on this video or GitHub sample.
Prerequisites
Create a new Blazor App in Visual Studio
You can create a Blazor Server App or Blazor WebAssembly App using Visual Studio via Microsoft Templates or the Syncfusion® Blazor Extension.
Install Syncfusion® Blazor StockChart and Themes NuGet in the App
To add Blazor Stock Chart component in the app, open the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), search and install Syncfusion.Blazor.StockChart and Syncfusion.Blazor.Themes. Alternatively, you can utilize the following package manager command to achieve the same.
Install-Package Syncfusion.Blazor.StockChart -Version 28.1.33
Install-Package Syncfusion.Blazor.Themes -Version 28.1.33NOTE
Syncfusion® Blazor components are available in nuget.org. Refer to NuGet packages topic for available NuGet packages list with component details.
Register Syncfusion® Blazor Service
Open ~/_Imports.razor file and import the Syncfusion.Blazor and Syncfusion.Blazor.Charts namespace.
@using Syncfusion.Blazor
@using Syncfusion.Blazor.ChartsNow, register the Syncfusion® Blazor Service in the ~/Program.cs file of your Blazor Server App or Blazor WebAssembly App.
using Microsoft.AspNetCore.Components;
using Microsoft.AspNetCore.Components.Web;
using Syncfusion.Blazor;
var builder = WebApplication.CreateBuilder(args);
// Add services to the container.
builder.Services.AddRazorPages();
builder.Services.AddServerSideBlazor();
builder.Services.AddSyncfusionBlazor();
var app = builder.Build();
....using Microsoft.AspNetCore.Components.Web;
using Microsoft.AspNetCore.Components.WebAssembly.Hosting;
using Syncfusion.Blazor;
var builder = WebAssemblyHostBuilder.CreateDefault(args);
builder.RootComponents.Add<App>("#app");
builder.RootComponents.Add<HeadOutlet>("head::after");
builder.Services.AddScoped(sp => new HttpClient { BaseAddress = new Uri(builder.HostEnvironment.BaseAddress) });
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. Reference the stylesheet and script in the <head> of the main page as follows:
-
For .NET 6 Blazor Server app, include it in ~/Pages/_Layout.cshtml file.
-
For .NET 7 Blazor Server app, include it in the ~/Pages/_Host.cshtml file.
-
For Blazor WebAssembly app, include it in the ~/index.html file.
<head>
....
<link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
<script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>
</head>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 Blazor Stock Chart component
Add the Syncfusion® Blazor Stock Chart component in the ~/Pages/Index.razor file.
<SfStockChart>
</SfStockChart>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.
<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 your 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.
<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.
<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.
<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}
};
}
