Pyqtgraph

PyQtGraph is a scientific plotting and graphics framework built for PyQt and PySide applications, providing fast, interactive 2D and 3D visualizations with GPU-accelerated rendering. It serves as both a real-time signal monitoring system for streaming time-series data and a toolkit for constructing interactive data dashboards with dockable panels, parameter trees, and custom widgets. The library also includes a node-based visual flowchart tool for building data processing pipelines and a scientific graphics export system that saves plots as PNG, SVG, or CSV and converts items to Matplotlib for publication output.

The framework distinguishes itself through its combination of high-performance rendering capabilities and flexible GUI construction tools. It renders 2D scientific plots using Qt's GraphicsView framework for responsive interaction, while 3D visualizations leverage OpenGL for real-time exploration of surfaces, volumes, and meshes. The library supports image and video display with color mapping and normalization, and provides interactive features such as mouse-based pan/zoom, data selection, and annotation with text labels, arrows, and region-of-interest selectors.

Beyond core plotting, PyQtGraph offers capabilities for building complete scientific interfaces, including dockable panel layouts, parameter tree controls, and custom widget embedding. It handles data processing through NumPy array operations, supports multi-dimensional data slicing, and enables export to HDF5 format. The library also integrates with Jupyter notebooks for exploratory analysis and provides SI unit conversion for readable axis labels.
