Why ProEssentials?

GPU Compute Shader Architecture

ProEssentials uses DirectX compute shaders for scene construction — not a game-engine render loop. The GPU activates only when data changes, keeping CPU and power usage low.

100 million completely new data points, rendered every 15ms (~66 fps). Each update cycle, the full dataset is transferred to the GPU via a staging buffer, then processed through two compute shaders — a reduction shader and a render shader — to produce the final image. No resampling, no data reduction, no lossy downsampling. Your data hits the screen exactly as it exists in memory. Run the GigaPrime2D example in our full evaluation to see it live.

This is the same architecture that enables zero-copy data binding via UseDataAtLocation(), where the chart reads your existing float[] array in place — no internal copy, no float-to-double conversion, no object-per-point allocation.

Five Chart Objects, Every Chart Type

Zero Licensing Friction

• Perpetual license — pay once, use forever, no subscription
• No runtime key — no license key embedded in your code
• No activation server — works offline, air-gapped, xcopy deploy
• No account required — evaluate immediately from this NuGet package
• Evaluation mode shows a watermark only — your app runs fully functional

Free Unlimited Support — From the Developers

Support is free, unlimited, has no ticket cap, and never expires. When you email a question, the engineers who designed and built the rendering engine answer directly. No escalation chain, no tier system, no chatbot. This applies for the lifetime of the version you purchased.

📧 support@gigasoft.com — just ask.

AI Code Assistant

ProEssentials includes pe_query.py, a Python-powered tool that gives AI assistants (Claude, ChatGPT, etc.) on-demand access to the complete API — 1,104 properties, 1,260 methods, 167 enums — with ground-truth validation against the compiled DLL binary. The AI checks every property path before delivering code, eliminating hallucinated API calls.

Advanced Tip: Manual Assembly Reference

For teams that prefer direct control over dependencies (especially in large solutions or CI pipelines), you can also reference the ProEssentials assembly manually by adding a <Reference> with <HintPath> directly in your .csproj file. Download the full evaluation from gigasoft.com to get the DLLs locally, then point your HintPath to the local assembly. If you use the default v10 assembly folder locations, installing the latest v10 setup will automatically update your projects. This is entirely optional — the NuGet package works normally with Visual Studio's package management.
