PyQtGraph is a pure-Python graphics and GUI library built on PyQt/PySide and NumPy for fast 2D/3D scientific plotting and interactive data visualization. It provides realtime plotting, image display, region-of-interest tools, and 3D volumetric rendering aimed at mathematics, science, and engineering applications.
Use cases
- plot realtime sensor data in a python desktop app
- display and slice multidimensional image data like MRI scans
- build interactive 2D line and scatter plots with pan/zoom
- render 3D volumetric data and isosurfaces
- add region-of-interest selection to image analysis tools
- create scientific GUI applications with fast plotting widgets
- visualize data in jupyter notebooks
When to choose
- you need fast, realtime plotting in Python with Qt
- you want interactive scientific visualization without writing C/C++
- your app already uses PyQt5, PyQt6, or PySide6
- you need image display, ROI tools, or 3D volumetric rendering
When to avoid
- you need publication-quality static figures for papers (matplotlib is better suited)
- your project does not use Qt and you want a standalone plotting library
- you need web-based dashboards rather than desktop GUIs
