“ProEssentials is the undisputed heavyweight of Windows desktop charting. Version 11 brings its three-decade native C++ engine to WinUI 3, native ARM64, and .NET 10 — with AI assisting the modernization of its many interfaces, but never rewriting or compromising its core.
That core represents thirty years of our own engineering. Version 11 took seven months of thirteen-hour days, and every line AI produced was read, questioned, and judged against decades of graphics-programming experience. The only way to use AI is to read every line and reason over it — and every time we caught it cutting a corner, we pushed back and went down the rabbit hole instead.
The result is a uniquely capable piece of modern engineering — not only for commercial products, but for R&D, rapid prototypes, proof-of-concept demonstrations, test and measurement, internal data analysis, and one-off engineering utilities.
Any company serious about engineering will find countless uses for it, and with our AI code assistance many of those ideas become working applications in a few hours.
We are proud to ship ProEssentials as the world’s first charting component to faithfully deliver on Microsoft’s goal for WinUI as the modern, native, performant interface — presenting directly through a composition swap chain instead of a managed XAML layer.”

AI-Assisted Charting Development
ProEssentials v11 includes a purpose-built AI Code Assistant system that transforms how you implement charts. Instead of searching through documentation, describe what you need in plain English and let AI generate validated, working charting code.
The pe_query.py tool gives AI assistants on-demand access to the complete ProEssentials API — over 1,200 properties, 169 enumerations, and 116 working code examples. A built-in validation layer cross-checks every property path against DLL ground truth, eliminating the hallucinated code that plagues generic AI coding.
Works with Claude, ChatGPT, Gemini, GitHub Copilot, Cursor, and any AI tool that supports custom instructions. Included free with every ProEssentials v11 license.

Competitors drain your end-users' laptop battery by relying on generic open-source graphics/gaming logic that continuously outputs frames as if running a video game. Don't turn your app into a power hogging game.
In contrast, ProEssentials generates frames only on demand, sipping power to render graphics in your solutions.
Don't just take our word for it—put us to the test. Simply edit our GigaPrime3D or GigaPrime2D examples using a competitor's solution and compare the performance, power requirements, rendering quality, intelligence, and the amount of code required to replicate the demo's end-user functionality.
ProEssentials guarantees outstanding 2D and 3D rendering quality, exceptional speed, intuitive usability, and professional, responsive support. Trusted by thousands of developers and installed on millions of devices, ProEssentials powers desktop and embedded medical and industrial applications developed by leading engineering companies worldwide.
ProEssentials is lightning-fast. One click download and watch 100 million data points rendered losslessly in ~15 ms — and replaced wholesale, every frame, at ~15 FPS. ProEssentials communicates directly with GPUs via Direct3D API calls and charts using Direct2D where applicable. In v11 that same native engine drives our new WinUI 3 interface, so ProEssentials is the first premium WinUI charting library built on a native C++ engine instead of managed XAML. It employs lossless data-reduction algorithms when needed and continually ports CPU-side logic to GPU-side compute shaders for optimal performance. With ongoing speed improvements, ProEssentials is poised to be the fastest, most intelligent charting solution available.
Explore our demo to experience the rendering quality in 2D, 3D, Polar, Pie, and both continuous and discontinuous Date-Time axes. ProEssentials includes interfaces for WinUI, WinForms, WPF, WebForms, VCL, DLL, and OCX. With an affordable corporate unlimited-developer multi-year license and no additional support costs, ProEssentials is a logical choice. Build your charting prototype with ProEssentials to give your team and stakeholders the firsthand experience they need to make informed decisions about the best charting solution for your project.
ProEssentials is cost-effective, making it an easy choice for your organization's toolkit, empowering all employees to utilize it as needed.
As an engineer, base your decisions on hands-on experience.
As a product manager, choose solutions that prioritize both the end-user and your company's goals.
Exceptional Support That Exceeds Expectations
When customers encounter challenging issues, we recommend adding our PeFunction.SaveObjectToFile function call at the end of their initialization code. By sharing this file with us via email, we can load it using LoadObjectFromFile, analyze the problem, and provide a detailed explanation of the cause. While this process requires time and effort, we offer it repeatedly at no additional charge. Gigasoft's customer support is unparalleled in dedication and quality—resolving issues efficiently without involving your upper management or accounting teams. This level of service alone justifies the value of our license.
