Question

Python 的实时绘图库选哪个好

Answer 1

• Matplotlib
  速度慢，适用于绘制高质量的图像，但不适用于快速的实时绘图。PyQtGraph官网
  对此评论为：If you are doing anything requiring rapid plot updates, video, or
  realtime interactivity, matplotlib is not the best choice.

• PyQwt
  不支持PyQt5，还有就是不再维护了，PyQtGraph官网
  对此评论为：Its main drawback is that it is currently unmaintained and can be
  difficult to get working on a variety of platforms. Hopefully in the
  future it may find a new maintainer, but until then it may be best to
  avoid PyQwt.

• PyQtGraph
  使用Python编写，支持PyQt4和PyQt5，最新发布版本为0.10.0停留在2016年。

• PythonQwt
  使用Python编写，支持PyQt4和PyQt5，PythonQwt的GitHub主页
  对此介绍为：The PythonQwt package is a 2D-data plotting library using Qt
  graphical user interfaces for the Python programming language. It is
  compatible with both PyQt4 and PyQt5.

• guiqwt
  和PythonQwt是同一作者，基于PythonQwt做了功能扩展，最新发布版本为3.0.3停留在2016年。
