Qt import QtWidgets import typing __all__ = ['MatplotlibWidget'] The example above would open a window displaying a line plot of the data given. I have benchmarked the code but would like clarification on the results seeing as I can blit the Matplotlib plot to dramatically reduce the plot time. backends. It's based on pyqtgraph and it can easily handle data rates of ~100Hz. 关于 pyqtgraph 与 Matplotlib 的对比，大致要点如下： pyqtgraph 在画图方面不如 Matplotlib 功能完整和成熟，但运行更快; Matplotlib 旨在绘制高质量图像，pyqtgraph 则主要面向数据抓取和数据分析的 . Compare price, features, and reviews of the software side-by-side to make the best choice for your business. You have multiple options available for adding interactive plots to your Python GUIs.
