I visited the scipy site for PyLab. I could not find its documentation there. The matplotlib site also does not provide any information on it.

Where can I find a tutorial/documentation on PyLab?

Pylab is basically just Numpy and Matplotlib under a unified namespace. Learn about either of those and you will understand Pylab.

If you want to plot things in scripts it is generally preferred that you use import matplotlib.pyplot instead of import pylab, but really the choice is up to you.

If you want to have interactive plotting (for instance, by calling ipython --pylab) then pylab is the way to go. However pyplot can also be put in an interactive mode using pyplot.ion().

Some more information can be found here:

What is the difference between pylab and pyplot?

Exact semantics of Matplotlib's "interactive mode" (ion(), ioff())?

  • I have tried pyplot. I want to update my graph and a question here on SO says for interactive graphs/plots I have to look at pylab, thus I wanted more information about it. – praxmon Apr 01 '14 at 09:47
  • I've added some more info to my answer. If you can already use `matplotlib`, there is nothing particularly new for you to learn to use `pylab`. The vast majority of the commands are the same. – ebarr Apr 01 '14 at 09:58
