Fast data visualization and GUI tools for scientific / engineering applications - pyqtgraph/pyqtgraph PyQtGraph 是一个用于创建科学绘图应用程序的 Python 库。它构建在 PyQt 和 PySide 基础上，并提供了高性能的绘图功能、实时数据绘制和交互性可视化。PyQtGraph 的主要特点包括：高性能绘图：PyQtGraph 使用 OpenGL 进行硬件加速，因此能够处理大量的数据点，而不会导致性能下降。 Modern OpenGL Pipeline: Leverage the full potential of the modern OpenGL pipeline to create visually appealing and efficient 3D graphics. This holds true for Win10 with OpenGL enabled only. mkQApp ("multiple views") win = QtWidgets. But it is not simple to switch the painter between the OpenGL "native mode" and the normal Qt behavior. Regardless, it sounds like pyqtgraph is expecting glDrawElements to do the appropriate conversion on their end, and this is an issue with PyOpenGl, not pyqtgraph.

(Note that subclasses must call setupGLState before painting for this to work) The simplest way to invoke this method is to pass in the name of a predefined set of options (see the GLOptions variable): ===== ===== opaque Enables depth testing and disables blending import numpy as np import pyqtgraph as pg import pyqtgraph. Some of the 3D Graphic examples fail when running the examples under native Wayland (no XWayland). 8k. Nice find @pijyoi I would make this is a "good first issue" but this is sort of tricky to test the fix of.
