Register Syncfusion® Blazor Service
Open~/_Imports.razor file and import theSyncfusion.Blazor andSyncfusion.Blazor.Charts namespace.
@using Syncfusion.Blazor@using Syncfusion.Blazor.ChartsNow, register the Syncfusion® Blazor Service in the~/Program.cs file of your Blazor WebAssembly App.
usingMicrosoft.AspNetCore.Components.Web;usingMicrosoft.AspNetCore.Components.WebAssembly.Hosting;usingSyncfusion.Blazor;varbuilder=WebAssemblyHostBuilder.CreateDefault(args);builder.RootComponents.Add<App>("#app");builder.RootComponents.Add<HeadOutlet>("head::after");builder.Services.AddScoped(sp=>newHttpClient{BaseAddress=newUri(builder.HostEnvironment.BaseAddress)});builder.Services.AddSyncfusionBlazor();awaitbuilder.Build().RunAsync();....Add stylesheet and script resources
The theme stylesheet and script can be accessed from NuGet throughStatic Web Assets. Include the stylesheet and script references in the<head> section of the~/index.html file.
<head> ....<linkhref="_content/Syncfusion.Blazor.Themes/bootstrap5.css"rel="stylesheet"/><scriptsrc="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js"type="text/javascript"></script></head>NOTE
Check out theBlazor Themes topic to discover various methods (Static Web Assets,CDN, andCRG) for referencing themes in your Blazor application. Also, check out theAdding 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 aIEnumerable object to theDataSource property. It can also be provided as an instance of theDataManager.
@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 theStockDetails toDataSource property. By default, Stock Chart will be rendered based on the providedDate andHigh fields value from datasource without any mapping.
<SfStockChart><StockChartSeriesCollection><StockChartSeriesDataSource="@StockDetails"Type="ChartSeriesType.Candle"XName="Date"YName="Close"High="High"Low="Low"Open="Open"Close="Close"Volume="Volume"></StockChartSeries></StockChartSeriesCollection></SfStockChart>PressCtrl+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 usingTitle property can be added in the Stock Chart, to provide quick information to the user about the data plotted in the component.
<SfStockChartTitle="AAPL Historical"><StockChartSeriesCollection><StockChartSeriesDataSource="@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 usingEnable property in theStockChartCrosshairSettings. Likewise tooltip label for an axis can be enabled by usingEnable property in theStockChartTooltipSettings.
<SfStockChart><StockChartCrosshairSettingsEnable="true"></StockChartCrosshairSettings><StockChartSeriesCollection><StockChartSeriesDataSource="@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 theEnable property in theStockChartCrosshairSettings totrue andShared property in theStockChartTooltipSettings totrue in component.
