G3P

G3P (GnuPlot Plus Plus) is a tiny but mighty header-only Modern C++ interface library for gnuplot. It is the most natural and intuitive way of adding gnuplot support to any C++ program.

A unique feature of G3P is the ability to embed plots/animations in Jupyter C++ Notebooks with Xeus-Cling kernel for rapid prototyping. If you have Docker, an easy way to learn about this feature is to run the prebuilt container:

docker run -p 8888:8888 -it --rm asobhani/g3p

If you don't have Docker, an easier but much slower way is to click on badge to launch it on Binder.

Key features include:

• 🖥️ Multiplatform (Linux/macOS/Windows)
• 💥 No dependencies (except gnuplot)
• 🖇️ Header-only (only one header file)
• 🪶 Lightweight (~300 lines of code)
• ⚡ Fast (all i/o implemented with C API and C++11 threading)
• 📊 Support embedding plots/animations in Jupyter C++ Notebooks backed by Xeus-Cling kernel
• 🏫 Easy to learn. If you know gnuplot, you're already set.
• 📥 Easily integrates with existing libraries and code (via CMake configs)
• ➡️ Support fluent interface
• 🔀 Support both C (%d,%f, ...) and C++ (<<) conventions for passing arguments to gnuplot
• 🧪 Include Catch2 unit tests
• 📖 Well documented

Quick example

++
#include <g3p/gnuplot>
g3p::gnuplot gp; gp << "set samples" << 200 << "\n"    << "set style data points\n"    << "plot [-10:10] sin(x),atan(x),cos(atan(x))\n"
