Syncfusion® Blazor Sparkline Charts
The Syncfusion Blazor Sparkline Component displays lightweight, single-series data visualizations in a compact cell or inline format. Perfect for dashboards and data summaries, sparklines show trends at a glance without axis labels or legends.
Key Features
- Multiple Sparkline Types - Supports five sparkline types—line, area, column, win‑loss, and pie—to visualize trends in minimal space.
- Compact Inline Visualization - Designed to display data trends inside small cells, tables, dashboards, and tight UI layouts without requiring a full chart.
- Extensive Customization - Customize markers (first, last, high, low, negative), data labels, range bands, axis styles, colors, backgrounds, and borders for fine‑tuned visual output.
- Interactive Tooltips & Track Lines - Provide detailed insights with hover/tap tooltips and optional track lines for precise data identification.
- Axis Configuration Options - Configure numeric, category, or date axes with adjustable min/max values, custom styling, and positioning.
- Responsive Design - Automatically adapts to container size and works smoothly across desktops, tablets, and mobile devices.
- Globalization & Localization - Automatically formats numbers, dates, and times based on culture settings, with full right‑to‑left (RTL) language support.
- Accessibility Support - Compliant with accessibility standards, including keyboard navigation and screen reader support using WAI‑ARIA.
- Dashboard‑Ready - Ideal for KPIs, summaries, and trend snapshots where space is limited but insights matter.
- Blazor Server & WebAssembly Compatible - Fully supported in both hosting models and easy to integrate into any Blazor application.
