Hands-on engineering from the people who build ProEssentials — from a focused starter project to fully custom GPU-accelerated charting work.

Priority Expert Services

Priority Expert Services

$499

A focused engagement on a single, well-defined objective — your choice of:

  • Starter project — a working implementation built for your specific use case, with runnable code that produces your desired output
  • Performance review — a focused study of your existing application for performance, rendering quality, or correctness, with our findings

Contact us — send example images and details for the starter project you need, or your existing project files for a performance review. Larger implementation work is handled as a Custom Enhancement quote.

Custom Enhancements

Custom Enhancements

from $1,000

Custom charting and rendering work engineered to your needs — typically $1,000-$5,000+ depending on scope. Examples:

  • GPU-accelerated, ComputeShader-based Direct3D plotting built for maximum throughput — quite possibly the fastest rendering path available for your data
  • Custom chart types and custom shader effects
  • GPU compute kernels — FFT, interpolation, decimation, filtering
  • Large-dataset handling for millions of points
  • Custom file formats and data pipelines
  • High-quality image and vector export
  • Migration from an existing or competitor charting solution

Support is included, free. We're glad to answer questions, look over a sample of your code, and help you get on the right track — sometimes even using our own AI resources to put together a working repo when time permits. This typically runs up to about an hour of our time; if your need grows into building a complete solution for your specific case, we'll let you know it's a good fit for our Priority Expert Services, and we'll explain exactly what that involves before any cost.
