ProEssentials WPF Quickstart — Simple Scientific Graph

A minimal, fully working WPF .NET 8 example demonstrating the Pesgo (Scientific Graph Object) from Gigasoft ProEssentials. Clone, build, run — no configuration required.

ProEssentials WPF Quick-Start

What This Example Shows

This is a self-contained WPF implementation of Example 100 — Simple Scientific Graph, the foundational Pesgo example in the ProEssentials library. The full example suite, including C#, C++ MFC, and VBA versions, is available at:

➡️ gigasoft.com/examples/100

Example 100 is the base that many subsequent ProEssentials examples build upon — other examples in the suite introduce their feature and show only the difference from this starting point.

What You'll See

  • 4 subsets (Horsepower, Torque, Temperature, Pressure) × 120 points each
  • Continuous XY data — X axis values at 100, 200, 300... intervals
  • Spline plus point plotting with gradient and bevel effects
  • Dark theme via QuickStyle.DarkNoBorder
  • Direct2D GPU rendering with anti-aliasing
  • Hover tooltip showing XY values
  • Left-click drag to zoom, right-click for full context menu
  • Built-in export, print, and customization dialog

Prerequisites

  • Visual Studio 2022
  • .NET 8 SDK
  • Internet connection for NuGet restore

How to Run

1. Clone this repository
2. Open ProEssentialsWpfQuickstart.sln in Visual Studio 2022
3. Build → Rebuild Solution  (restores NuGet package automatically)
4. Press F5

Right-click anywhere on the chart to explore the built-in context menu — export, print, zoom reset, and full property customization are all built in.

Key Concepts in the Code

Pesgo vs Pego — Pesgo is the Scientific Graph Object. Unlike Pego which assumes equally-spaced X values, Pesgo requires explicit PeData.X[s,p] values alongside PeData.Y[s,p]. Use Pesgo for scientific, engineering, and any data where X spacing is irregular or meaningful.

Control Loaded event — ProEssentials initialization must happen in the control's own Loaded event (Pesgo1_Loaded), not the window's Window_Loaded event. The window loaded event fires before the control is fully initialized.

ReinitializeResetImage() — always the last call after setting properties. Triggers the full data-to-image render pipeline.

NuGet Package

This project references ProEssentials.Chart.Net80.x64.Wpf from nuget.org. Package restore happens automatically on build.
