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

new SalesInfo { Month = "Feb", SalesValue = 28 },
new SalesInfo { Month = "Mar", SalesValue = 34 },
new SalesInfo { Month = "Apr", SalesValue = 28 },
new SalesInfo { Month = "May", SalesValue = 40 },
new SalesInfo { Month = "Jun", SalesValue = 32 },
new SalesInfo { Month = "Jul", SalesValue = 35 },
new SalesInfo { Month = "Aug", SalesValue = 55 },
new SalesInfo { Month = "Sep", SalesValue = 38 },
new SalesInfo { Month = "Oct", SalesValue = 30 },
new SalesInfo { Month = "Nov", SalesValue = 25 },
new SalesInfo { Month = "Dec", SalesValue = 32 }
};
}
Mobile-first approach
Develop Blazor Charts with single code base, and well-thought-out mobile adaptive architecture that adapts to any web, mobile, or tablet environment. Render beautiful, responsive, interactive, and animated Charts within mobile devices.
Accessibility
Keyboard navigation
Blazor Charts ensures that every element is keyboard accessible. Major features like selection, highlight, tooltip, legend collapse and zooming and panning can be performed using keyboard commands alone; no mouse interaction is required. This helps in creating highly accessible applications using this component.
Screen reader
Blazor Charts views have complete WAI-ARIA accessibility support. This UI includes high-contrast visual elements, helping people with visual impairments have the best viewing experience. Also, valid UI descriptions are easily accessible through assistive technologies such as screen readers.
Right to left (RTL)
Right-to-left rendering allows displaying the text and layout of the Blazor Charts from right to left. This improves the user experience and accessibility for RTL languages.

Where can I find the Syncfusion Blazor Charts demo?
You can find our Blazor Charts demo, which demonstrates how to render and configure the Charts.
How do I bind data to a chart?
Data can be bound by assigning a collection of data objects to the chart’s DataSource property and mapping the required fields (such as X and Y values) through the chart series settings.
Do Blazor charts require JavaScript interop, or are they native C#?
Syncfusion Blazor Charts use a hybrid architecture in which component states and business logic run natively in C#, while rendering still requires JavaScript interop through Canvas. For dense data arrays (100,000+ points), the pipeline offloads rendering to HTML5 Canvas, reducing interop overhead. Event handling and property updates still cross the Blazor-JS boundary. Performance improvements vary based on dataset size and event frequency.
Do these charts support real-time data streaming via SignalR?
Syncfusion supports real-time SignalR data streaming with three key optimizations: Direct data appending (points appended without a full chart redraw), Selective state updating (only affected series recalculate while axes and legends remain static), and SignalR cycle efficiency (optimized for high-frequency updates). These optimizations work together to prevent UI thread blocking. Maximum update frequency is typically 100+ updates/second, though actual performance depends on device capabilities and dataset size.
Can I download and utilize the Syncfusion Blazor Charts for free?
No, this is a commercial product and requires a paid license. However, a free community license is also available for companies and individuals whose organizations have less than $1 million USD in annual gross revenue, 5 or fewer developers, and 10 or fewer total employees.
How do I get started with Syncfusion Blazor Charts?
A good place to start would be our comprehensive getting started documentation.
How can I implement data aggregation with Blazor charts?
Data aggregation in Syncfusion Blazor Charts is possible using the built-in GroupTo property for accumulation charts (pie, doughnut) or by processing the data manually with C# LINQ before binding it to other chart types.
How do Blazor chart components impact application bundle sizes in WebAssembly (WASM)?
Blazor applications can have larger bundle sizes due to rich UI components. Syncfusion helps manage this with its modular design and support for .NET IL trimming . In Release builds, unused code is removed during the build process, ensuring that only the required chart functionality is included. As a result, the final WASM payload remains optimized based on actual usage.
Is it possible to export Blazor chart displays directly to downloadable documents?
Yes, Syncfusion Blazor Charts provide built-in export functionality to download chart visuals and data in multiple formats, including PNG, JPEG, SVG, PDF, and Excel/CSV.Exports can be triggered with simple method calls in both Blazor Server and WebAssembly applications. The exported output typically includes either the chart image or the underlying data, depending on the selected format.For large datasets, export performance may vary, so it’s recommended to use asynchronous handling where needed.
