I've never used matlab (and hope never to have to). But I've been using pyplot
api for mpl for quite a while.
Is there any good reason to move to the "native" mpl api and drop pyplot? I ask
because as I understand, pyplot is intended as a matlab workalike, and since I
never learned matlab I have no need for that crutch. OTOH, I'm quite used to
the pyplot api at this point.
I wrote up my answer to this question on stackoverflow once: https://stackoverflow.com/questions/19895262/when-to-use-the-matplotlib-pyplot-class-and-when-to-use-the-plot-object-matplot/21004357#21004357
Others may have different opinions or variations on the theme, but this is how I look at the issue. It is also the reason why I don’t want to deprecate pylab (but do want to keep it out of examples).
Cheers!

The only pyplot function I let myself use is plt.subplots() to quickly create the Figure and Axes objects. From that point on, I operate on those objects directly. Frankly, it reads almost exactly like pyplot code, but it is a lot more clear what’s going on.

99.9% of the time I am using pyplot, as it usually does what I want without me having to understand an api.
I don't care so much if pyplot agrees with matlab or not, but it should be something easy that new users can pick up quickly.
Best,

Hi Neal,
I always followed what has been written here:
http://matplotlib.org/faq/usage_faq.html#matplotlib-pylab-and-pyplot-how-are-they-related
And they said,
------------------
Matplotlib, pylab, and pyplot: how are they related?
Matplotlib is the whole package; pylab is a module in matplotlib that
gets installed alongside matplotlib; andmatplotlib.pyplot is a module
in matplotlib.
Pyplot provides the state-machine interface to the underlying plotting
library in matplotlib. This means that figures and axes are implicitly
and automatically created to achieve the desired plot. For example,
calling plot from pyplot will automatically create the necessary
figure and axes to achieve the desired plot. Setting a title will then
automatically set that title to the current axes object:
import matplotlib.pyplot as plt
plt.plot(range(10), range(10))
plt.title("Simple Plot")
plt.show()
Pylab combines the pyplot functionality (for plotting) with the numpy
functionality (for mathematics and for working with arrays) in a
single namespace, making that namespace (or environment) even more
MATLAB-like. For example, one can call the sin and cos functions just
like you could in MATLAB, as well as having all the features of
pyplot.
The pyplot interface is generally preferred for non-interactive
plotting (i.e., scripting). The pylab interface is convenient for
interactive calculations and plotting, as it minimizes typing. Note
that this is what you get if you use the ipython shell with the -pylab
option, which imports everything from pylab and makes plotting fully
interactive.

Gotta remember to update this paragraph… the -pylab option has been long deprecated, and is supposedly about to be removed in an upcoming release of ipython.
