The Only JavaScript Chart Library You’ll Ever Need

Redefine what’s possible in data visualization — from ambitious projects to real-time scale, SciChart JS delivers flexibility, depth, and power other libraries can’t match.

With 70+ 2D & 3D chart types, you can tackle ambitious data-visualization projects without compromise.

You’ll hit browser limits before you hit the limits of SciChart JS — rendering 100M+ points and powering dashboards with hundreds of real-time charts, all with GPU acceleration and seamless React, Vue, Angular, or plain JS integration.

Elevate your JavaScript projects with one of the world’s most robust and flexible charting libraries.

Everything You Need to Build JavaScript Charts

Here’s how SciChart helps you build advanced, high-performance JavaScript charts from day one.

Exceptional Performance

  • Create charts that don’t lag, for the most demanding big-data applications
  • Build dashboards that stay smooth and stable for days — no crashing
  • Render real-time charts for medical, fintech, IoT, defense, and telemetry
  • Render millions of data-points at 60 FPS with zero frame drops
  • Run dashboards with hundreds of live-updating charts
  • You’ll hit the limits of the browser before you hit the limits of SciChart
  • All enabled by our WebAssembly engine with GPU acceleration, low memory usage, and no WebGL context caps

Extensive Charting Features

  • Build advanced visual systems for polar, radar, vector, and hierarchical data
  • Create geospatial platforms with vector maps, overlays, and choropleth visualizations
  • Power AI interfaces with real-time visual feedback for ML models
  • Design custom UI dashboards with full layout, event, gesture, and overlay control
  • Embed interactive content directly inside charts
  • Render custom visuals without performance penalties
  • Control render order — decide what draws first, last, and where
  • Customize appearance by creating your own themes
  • Animate any element in your chart
  • Exceptional flexibility – any chart type, any layout, any combination of interactivity modifiers

Build Real-Time JavaScript Charts with Confidence from Day One

Tired of outdated docs or half-baked GitHub examples? With SciChart, you can get a real-time JavaScript chart running in under two minutes using production-ready templates and tutorials — no WebAssembly setup required, no complex wrappers, just clean code.

More Power & More Performance

You’re building systems where performance isn’t a feature — it’s a requirement. Whether that’s real-time telemetry or high-frequency trading, most JavaScript libraries can’t handle this kind of pressure.

Cross-platform access, unlimited flexibility and proven big data performance all work together to solve some of the biggest setbacks in data visualizations.

By far the best company I have ever worked with! The response time and quality of the support is world class!

Support From Real Data Engineers

Whether you’re debugging a dashboard or pushing performance limits, our support team is trusted by developers worldwide. With 500+ five-star reviews on Reviews.io, Capterra, and G2, our product and support consistently earn high praise.

You’ll also find the largest library of documentation, tutorials, and live examples—everything is practical, well-organized, and easy to search. Developers often mention how quickly they find exactly what they need.

On top of that, our SciChart GPT tool helps you get there even faster—pointing you to the right docs, demos, or code snippets.

Customizations that Open Up New Data Visualization Possibilities

Unlike most libraries, SciChart.js doesn’t force you to choose between speed, adaptability, or simplicity. It’s engineered for serious applications with WebAssembly-accelerated performance, advanced chart types, and deep customization.

SciChart.js gives you full control—extend series, create custom annotations, define interactions, or override rendering logic. The API is designed to let your charts look and behave exactly as your application requires.

Endless Charting Possibilities at Your Fingertips

SciChart.js v4 includes advanced chart types rarely found in JavaScript libraries. Beyond fast line, scatter, and column charts, it adds rectangle, triangle, box plot, and polygon series—on both Cartesian and polar surfaces. With 70+ 2D and 3D types, including radial, gauges, heatmaps, GeoJSON maps, and full 3D charting, SciChart enables visualizations few other libraries can achieve.

Performance that Doesn’t Slow Down

Advanced JavaScript Chart API: Extensible and Customizable

SciChart’s JavaScript Chart API has been shaped over a decade with input from thousands of developers and end-users. It offers a deep feature set designed for extensibility and customization, giving you full control over how charts behave and render.

  • Theme everything down to the pixel, animating datasets, styles, and transitions without performance loss.
  • Add annotations and labels at scale, thousands, draggable and editable.
  • Point-and-click data editing (curves, heatmaps, parameters).
  • Unlimited and mixed axes (linear, log, date, category) with custom layouts.
  • Multi-chart linking to sync zoom, pan, tooltips, and cursors.
  • Built-in hit-testing APIs for precision interactivity.

Licensing Made Simple

Great tech shouldn’t come with mystery pricing. We’ve simplified everything with visual guides and GPT support — so you always know what you’re getting.

Back in 2014 we investigated into more than 10 different WPF charting libraries to replace our existing charts. SciChart already at that time was for us the best solution. Performance, API, feature set and even support are outstanding. Bugs getting fixed very fast without killing the quality assurance (as already seen by other well known WPF library vendors).

High performance, multiple useful features, easy to use, and good documentation with detailed tutorials and examples. We applied SciChart in a DAQ&Testing system to display signals in real-time. This software definitely met our requirements.
