PyQtGraph在这里是一个不错的选择，实时绘制125个样本/秒应该没问题.您可以使用多种方法来绘制实时数据，滚动数据，并且PyQtGraph中实际上有一个很好的示例文件，该文件仅显示以下内容:

PyQtGraph is a pretty good choice here and it should be no problem to plots 125 samples/second in real time. There are several approaches you could use for plotting real-time, scrolling data and there actually is a good example file in PyQtGraph showing just that: https://github.com/pyqtgraph/pyqtgraph/blob/develop/examples/scrollingPlots.py

您可以通过在安装PyQtGraph之后在Python解释器中运行此示例来运行示例:

You can run the example by running this in your Python interpreter after installing PyQtGraph:

import pyqtgraph.examples
pyqtgraph.examples.run()

，然后选择滚动图"示例.

and selecting the "Scrolling plots" example.
