• Flexible data binding with support to use local and remote data sources such as JSON, RESTful services, OData services, and WCF services.

• One of the best JavaScript Charts in the market that offers feature-rich UI to interact with the software.

• Simple configuration and API.

• Supports all modern browsers.
• Mobile-touch friendly and responsive.

• Expansive learning resources such as demos and documentation to learn quickly and get started with JavaScript Charts.

You can find our JavaScript Charts demo, which demonstrates how to render and configure the Charts.

A JavaScript Chart renders series based visualizations (line, bar, area, financial, etc.) as JavaScript components. Syncfusion’s JavaScrript Charts ship with 55+ chart types, high performance rendering, and built in interactions (zoom, pan, tooltip, crosshair, trackball) to turn raw data into responsive, accessible visuals quickly. They also use a hybrid SVG + Canvas rendering engine for high performance visualization.

Start with your comparison goal: trends (line/spline/area), rankings (bar/column), distribution (histogram/box plot), composition (pie/doughnut/stacked), relationships (scatter/bubble), and financial series (candlestick/OHLC). With 55+ chart types available, you can match any of these needs, all configurable via props.

Use DataManager with WebApiAdaptor, ODataAdaptor, or ODataV4Adaptor; map fields with xName/yName, and use query for filtering/sorting. Offline mode can cache data on the client when latency is a concern.

Call the chart’s exportModule.export(…) to output PNG/JPEG/SVG/PDF, or export underlying data as XLSX/CSV; printing is supported via print(). You can export multiple charts at once, add PDF headers/footers, and customize Excel output. See the docs and live demo. Exporting requires injecting the ExportModule.

Charts are mobile friendly and responsive by design, with pinch to zoom/scroll and toolbar controls for small screens. Use layout friendly containers and responsive legend/tooltip options to refine UX on phones and tablets. The chart also auto adjusts axes labels, legends, and tooltips based on screen size.

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.

A good place to start would be our comprehensive getting started documentation.

Create a JavaScript app, install @syncfusion/ej2-javascript-charts, and add with injected modules (e.g., LineSeries, Legend, Tooltip). The Getting started guide includes TSX/JSX snippets, module injections, markers, legends, titles, and tooltips so you can run a working chart in minutes. Syncfusion also provides ES modules fully compatible with Vite, CRA, and Next.js

Charts are engineered for speed (rendering ~100K points quickly). For streaming or large data, use lazy loading/scrollbars and DataManager for server side paging or filtering; the API supports efficient updates and responsive zoom/pan for inspection.

Turn on interactions via props and module injection: zoomSettings (selection, mouse wheel, pinch, toolbar), tooltip=, crosshair=, and enable trackball for near point inspection. Docs include code for each interaction.

You can style series, axes, palettes, markers, labels, and legends through props; enable smart labels, animations, and themes. The package also documents palette/theming options and extensive appearance APIs. Built in themes include Material, Fluent, Tailwind, and Bootstrap.

Yes. The component follows ADA/Section 508/WCAG 2.2 guidelines, supports WAI ARIA roles/labels, keyboard navigation, and high contrast visuals ideal for accessible dashboards in enterprise apps.
