How to use MATPLOTLIB to make GRAPHICS [Course

Python gives us access to a whole diversity of alternatives for producing static and dynamic visualizations, both in 2D and 3D. In particular, the Matplotlib package is the most widely used option for visualization and is integrated in several pillars of the Python scientific platform, such as: Pandas, IPython and Jupyter.

The code that replaces punctuation marks in the above example could be implemented more synthetically by employing the .maketrans() and .translate() methods associated with text strings or even using regular expressions. For example:

Pandas and Matplotlib¶Pandas integrates Matplotlib functionality into its DataFrame and Series objects, so sometimes getting a plot with data from a Pandas object is as easy as invoking the .plot() method.

Tip 2: It is always advisable to read the documentation of a library or tool, as they usually have in-depth explanations of how the functions operate, as well as tutorials and examples. Matplotlib accomplishes this by having an example section and a tutorial section.

The internet is full of tutorials and information of all kinds, so much that at times it can be difficult to choose. That’s why after each example we recommend some tutorials and examples, so you can save yourself the indecision. Apart from all that, we also recommend this tutorial once you have finished reading this article.

The first step for all these examples is to import what you need. As we have already seen the library is huge, it has a lot of modules and approximately 70,000 lines of code. But we are only interested in the pyplot module. That’s why our first line of code will be the following:

We would be importing the whole library including the modules we are not interested in. Adding the “.pyplot” ensures that only the module we want will be imported. Now we have all the functions of the pyplot module. But to use each one of them we would need to write

From what has been said, we can deduce that matplotlib is a low-level library, very powerful and extensive, but it can be a bit confusing at the beginning. It offers tools for the creation of 2D visualizations, although it is completed with the use of other add-ons that allow the generation of 3D graphs (mplot3d) and maps (basemap).

Logically, to make use of any function offered by the matplotlib.pyplot library, it must be imported using the commented instruction. In the examples shown throughout this tutorial this instruction is not shown, but it is always the first one to be executed in the Jupyter notebook:

Built on matplotlib, seaborn is a high-level library, which abstracts visualizations in a way that is easy to configure, disaggregate, compose, and includes statistical functionality. That means that seaborn also produces or manipulates figures, so it can be complemented with matplotlib’s own tools or others that are also built on the same base.

pandas and geopandas are data analysis libraries (tabular and geographic, respectively). They include basic visualization functionality, which can be extended with code from matplotlib and seaborn, since their visualization functions themselves work on top of matplotlib figures. pandas has an extensive visualization module, as does geopandas.

aves is my own repository of tools, which I have decided to start collecting and organizing to make it available for this course (and for anyone who wants to use it in their own projects). It can be downloaded from the aves repository on github.
