在 .NET 中为图表添加键盘导航

Charts with keyboard navigation support are designed to improve accessibility and usability by allowing users to explore chart data using only the keyboard. This feature is especially valuable for users who rely on assistive technologies or prefer keyboard interaction over a mouse. It typically includes capabilities like navigating between data points, series, or chart elements using arrow keys, accessing tooltips or data labels, and sometimes triggering events like selection or focus changes, all through the keyboard.

Several .NET chart components support keyboard navigation, including:

• DevExpress ASP.NET MVC Chart (part of DevExpress ASP.NET and Blazor) supports accessibility features, allowing keyboard interaction across UI components.
• Telerik UI for ASP.NET Core Charts (part of Telerik UI for ASP.NET Core) includes support for arrow key movement between data points and ARIA integration.
• jQWidgets Chart (part of jQWidgets) is part of a framework that emphasizes WAI-ARIA compliance and keyboard interaction across its widgets.
• Syncfusion .NET MAUI Charts (part of Syncfusion Essential Studio Enterprise) is built on a platform supporting keyboard input, extendable to visual components in custom apps.
