Introducing a high-performance charting library for the web

SciChart uses WebGL and WebAssembly to render millions of data points and hundreds of charts directly in the browser.

#2about 4 minutes

Tracing the evolution from native WPF to the web

The library began as a high-performance solution for slow WPF applications before being ported to the web using C++ and WebAssembly.

#3about 3 minutes

Balancing raw performance with platform-specific flexibility

The core rendering engine is a cross-platform canvas, but developers still need hooks into the native platform for deep UI customization.

#4about 3 minutes

Using WebAssembly to bypass JavaScript performance issues

WebAssembly provides near-native speed by avoiding JavaScript's boxing and unboxing and enabling direct memory manipulation with features like WASM SIMD.

#5about 5 minutes

Managing extreme user expectations and browser limitations

Users expect applications to run flawlessly for days, requiring meticulous memory leak detection and management within the browser's sandboxed environment.

#6about 5 minutes

Exploring high-stakes use cases for performance charting

Industries like Formula One, medical monitoring, and industrial automation rely on visualizing massive, real-time datasets on complex dashboards.

#7about 5 minutes

The constant push for more performance and features

Client demands for hundreds or even thousands of synchronized charts drive continuous optimization of rendering, text layout, and data handling.

#8about 7 minutes

Advanced WebAssembly memory optimization techniques

Creating volatile array views over native WebAssembly memory allows for direct, unsafe memory access that can yield significant performance gains.

#9about 12 minutes

How documentation, AI, and feedback shape API design

A robust documentation process not only reduces support tickets but also provides structured data for AI assistants, whose feedback can influence API naming and clarity.

#10about 2 minutes

A call to challenge your web performance assumptions

Developers are encouraged to raise their expectations of what's possible in the browser and try the library's free community edition.
