PyGRA

PyGRA is an interactive scientific data plotter built with Python, PyQt5, and Matplotlib, inspired by xmgrace.

It provides a graphical interface for loading, transforming, fitting, and visualising multi-column data files — designed for researchers who need fast, flexible plotting without writing code every time.
