    Fastplotlib is a next-generation plotting library built using the pygfx rendering engine. It leverages Vulkan, DX12, or Metal via WGPU, making it extremely fast and suitable for large-scale exploratory scientific visualization.

    Key Features

    • GPU-accelerated visualization: Fastplotlib utilizes the power of modern GPUs to render complex visualizations quickly.

    • Interactive visualization: It provides an intuitive and expressive API for creating interactive visualizations.

    • Rapid prototyping: Ideal for rapid prototyping and algorithm design.

    • Large-scale data handling: Efficiently handles and renders large-scale data.

    • Machine learning model visualization: Useful for designing, developing, evaluating, and shipping machine learning models.

    • Real-time acquisition systems: Suitable for creating visualizations for real-time acquisition systems for scientific instruments like cameras.

    Supported Frameworks

    Fastplotlib can run on any platform that supports pygfx, including:

    • Jupyter Lab (using jupyter_rfb)

    • PyQt and PySide

    • glfw

    • wxPython

    How do I specify an event in fastplotlib?

    In fastplotlib, specifying an event is as simple as defining how we want to handle the event and then adding our handler to the appropriate graphic or plot the event corresponds to. The beauty of this approach is that it doesn’t require users to learn new, complicated, library-specific API features (knowing how to define functions is sufficient).
