What is a Pyplot?

pyplot is a collection of functions that make matplotlib work like MATLAB. Each pyplot function makes some change to a figure: e.g., creates a figure, creates a plotting area in a figure, plots some lines in a plotting area, decorates the plot with labels, etc. In matplotlib.

Why is PyLab used?

PyLab is a procedural interface to the Matplotlib object-oriented plotting library. PyLab is a convenience module that bulk imports matplotlib. pyplot (for plotting) and NumPy (for Mathematics and working with arrays) in a single name space. Although many examples use PyLab, it is no longer recommended.

34. The problem you are having is that bbox_inches=’tight’ just removes all of the extra white space around your figure, it does not actually re-arrange anything in your figure, after it has been rendered.

Adjust the y limits to suit your taste.

How to use pylab in an iPython notebook?

There are a few ways to invoke it: On startup, you can add a command line argument: ipython [notebook] –pylab. or: ipython notebook –pylab inline. The first can be used with the notebook or with the normal IPython interpreter. The second specifies that figures should be shown inline, directly in the notebook.
