SciChart: High-Performance JavaScript Chart & Graph Library

Discover the ultimate solution for your JS applications with SciChart’s JavaScript Chart Library.

Using WebGL to create dynamic, high-speed charts and graphs, perfect for handling complex data visualization in real-time. Elevate your JavaScript projects with our robust and flexible JS charting tools.

JavaScript Charts with a Difference

This is not your standard JavaScript Chart Library! With tens of thousands of properties on over 1,000 exported types, we’ve built SciChart.js to handle the most demanding JS charting & graphing requirements in ScientificMedical, Financial, AerospaceMotorsport & F1, or Oil & Gas.

JavaScript Chart Performance

SciChart’s incredible JavaScript Chart performance is enabled by our proprietary, in-house, C++ cross platform 3D graphics engine, Visual Xccelerator™. The engine is entirely hardware accelerated targeting WebGL & WebAssembly in the browser.

With SciChart’s JavaScript chart library, it is now possible to display millions of data-points in JavaScript line, scatter, or candlestick charts and update in real-time. It’s also possible to plot thousands of series, or hundreds of fast JavaScript Graphs on a single webpage without stalling your user interface.

JavaScript Charts for Complex Requirements

For complex, demanding charts in Aerospace, Motorsport & F1, or Oil & Gas, you need to take the interactions in your JS graphs to a new level.

With SciChart.js you can get callbacks on series hover, series selection, data-point selection and even update chart data via the mouse.

Don’t struggle to create complex requirements, use SciChart.js to achieve more, in less time.

JavaScript Charts Linked for Interactive Dashboards

Create rich dashboards with linked multiple charts. SciChart.js provides the building blocks to create JS Dashboards, complex financial or stock charts or apps with dynamic add/removal of linked chart panes.

Add two charts to your application, link them together in a group to synchronize zooming, sync cursors and optionally sync chart sizes. Multiple JS charts can act as one

Learn the SciChart.js Features

Our JavaScript Charts and Graphs feature list is so huge, we had to create this ridiculously detailed webpage. If you have a question about our Charts in JS, don’t get lost in our docs/demos, just ask!

Unlimited Multiple X, Y Axis

Our JavaScript Chart Library features unlimited, multiple X and Y axis.

Place many X-axis at the Top or Bottom and Y axis on the Left or Right. Several axes on one side are also possible. You can place X, Y axis in the centre. You can have hidden axis to scale data independently.

Create vertical charts by displaying X axis on the Left/Right and Y axis on the Top/Bottom. Stack axis vertically or horizontally to create an ECG chart. Mix Linear, Logarithmic or Category axis on the same chart and have unlimited custom layouts in our JavaScript Charts and graphs.

Annotations & Markers

Our JavaScript Chart Library features a powerful Annotations API that allows you to place annotations and markers over the chart at specific Xy data-points, or relative coordinates (%, pixel)

There are plenty of Annotations ready out of the box, e.g. line, box, text, and more. Custom annotations are possible if you want to display custom markers or points of interest.

SciChart’s JavaScript chart library supports interaction with annotations, where you can allow users to click on annotation, drag and resize.

Cursors, Tooltips & Legends

Add Tooltips to your JS charts and graphs with our range of behaviour modifiers. SciChart supports optional crosshairs, draggable vertical lines, placeable cursors, tooltips and legends out of the box.

Configure what’s displayed in the tooltip, format text and include additional metadata. React to legend interactions to show/hide series or toggle application state.

Advanced Zooming & Panning

Our JavaScript Charts provide you with APIs to zoom, pan, and scroll charts. You can allow your users to pan or zoom chart in X or Y directions or both; set or animate axis.visibleRange programmatically to pan or scale.

Listen to visibleRangeChanged events which callback on zoom. Scale or mousewheel axis independently. Or, develop custom mouse interactivity extensions via our powerful ChartModifier API within our JavaScript charting library.

Styling, Theming, Animating

Our JavaScript Charting Controls ship with 3 stunning themes in a Theme Manager, which you can apply to your charts with a single line of code. Themes affect default cursor, zoom, axis, grid and series colors.

You may customize your JavaScript charts even further and create your own custom theme.

Furthermore, anything can be animated including styles, data and transitions on mouse-hover or click.
